Partner Ranks

The IrukaDark Partner Program offers multiple ranks based on activity — referrals, sales, deployment support, and enterprise expansion. Compensation terms are determined individually based on sales performance, customer support, eligible plans, region, and contract type. Top-tier partners receive recurring rewards, co-marketing support, and joint enterprise proposal opportunities.

* Rank upgrades are determined by IrukaDark's review of partner activity (number of referrals, sales results, support quality, etc.) and may be adjusted at any time. Reward rates and terms for each rank may change upon review.

How the program works

Each partner receives a unique partner code. Once an end user enters this code in their IrukaDark account settings, that user's payments become eligible for partner rewards. End users may be individuals or businesses.

  1. Partner code issued
    After screening, you receive a unique code.
  2. End user enters the code
    The end user enters it in their account settings.
  3. End user pays
    Paid plan subscription or credit top-up.
  4. % of tax-exclusive payment as reward
    Your partner reward is calculated by applying your rank rate to the tax-exclusive amount.

Partner code and eligible revenue

Partner rewards are based on the Stripe invoice line subtotal for the following charges, before consumption tax or similar taxes and before discounts are applied:

  • Subscription fees (monthly or annual Plus / Max / Team plans)
  • Additional credit purchases (one-off credit top-ups outside the subscription are also eligible)

The applicable reward rate (Bronze ~20% / Silver ~30% / Gold & Platinum custom) is applied to the tax-exclusive, pre-discount total of the above.

Base reward example (10% tax, Bronze rank, ~20%)

  • 1 user on the Plus plan (tax-inclusive $9/mo) → about $8.18 tax-exclusive × 20% = about $1.64 base reward
  • 10,000 users on the Plus plan → about $81,818 tax-exclusive from tax-inclusive $90,000 × 20% = about $16,364
  • Team plan (tax-inclusive $12/member/mo) for 1,000 members × 10 teams → about $109,091 tax-exclusive from tax-inclusive $120,000 × 20% = about $21,818
  • Plus tax-inclusive $50 in additional credit purchases → about $45 tax-exclusive × 20% = about $9 added to that month's reward

* Calculations above are approximate examples for a 10% tax rate with no discounts, with displayed amounts rounded to whole dollars. Actual rewards are calculated in US dollars (USD) from the Stripe invoice line subtotal after rounding, before tax and discounts. Actual payouts are made in Japanese yen (JPY). See the Reward Payment Terms below for currency and payout details.

Activity formats

There are no specific restrictions on how the partner code is shared. Any of the following formats — or a combination — are allowed:

  • Direct referrals to acquaintances, business contacts, or social media followers (verbal, text, email, etc.)
  • Posting the partner code on your own website, blog, landing page, or newsletter (auto-application via links is also supported)
  • Sharing the partner code during seminars, study sessions, or webinars
  • Introducing the code to customers as part of AI deployment support, DX consulting, or internal training services

In all cases, please carry out activities within the bounds of applicable law and in accordance with the program's terms and guidelines.

Free plan handling

The partner code can be entered while the end user is on the Free plan. However, because Free is unpaid, no partner reward is earned during the Free period. If the user later upgrades to a paid plan (Plus / Max / Team), they automatically become eligible for partner rewards from that point on.

Enterprise plan handling

When a referred end user contracts an Enterprise plan, the contract amount, structure, and payment terms are negotiated individually. Accordingly, the partner reward terms (rate, payment timing, etc.) are also determined on a case-by-case basis.

Prohibited activity (self-referral)

Self-referrals — entering your own partner code on your own account to receive rewards for yourself — are prohibited. Applying your code to other accounts (including those owned by family members, separate accounts within the same legal entity, or separate legal entities operated by the same representative) is permitted. Violations may result in reward forfeiture, suspension or termination of partner status, and clawback of previously paid rewards.

Reward payment terms

The terms below apply to end users on Plus / Max / Team plans. For end users on Enterprise plans, payment terms are determined individually based on contract conditions.

Payment schedule
Rewards are finalized at the end of the month following the end user's payment, and the payout is processed on the 25th of the following month. The actual bank arrival depends on the external payment processor, but is expected to complete by the end of the payout month. Example: end user pays in January → reward finalized end of February → payout processed on March 25 → expected to arrive by end of March.
Currency & FX
Reward amounts are calculated in US dollars (USD), but payouts are made in Japanese yen (JPY). The USD-to-JPY conversion rate is determined by the external payment processor; we cannot control when the conversion occurs.
Minimum payout
$10. Rewards become payable once the accrued balance reaches $10. If the balance remains below $10 for 180 days after finalization, the unpaid amount is forfeited (a constraint under Japan's Payment Services Act).
Transfer fee
The bank transfer fee is generally JPY 300 per payout. It is deducted from the partner reward before the payout. The amount after deduction is the amount actually transferred.
Consumption tax
Consumption tax included in the IrukaDark fee paid by the end user and consumption tax on rewards paid by us to the partner are treated as separate transactions. The base reward is calculated exclusive of tax from the Stripe invoice line subtotal, before consumption tax or similar taxes and before discounts are applied. If the partner submits the registration number (T + 13 digits) and other required information, and we can confirm an active qualified invoice issuer registration through Japan's National Tax Agency publication site or an equivalent source, we add the applicable consumption tax amount to the base reward paid in Japanese yen. If the partner is not a qualified invoice issuer, does not submit the required registration information, or we cannot confirm an active registration, no consumption tax amount is added.
Withholding tax
IrukaDark does not withhold income tax. Recipients are responsible for their own tax filings as required.
Payout destination
Payouts use Stripe Connect. After screening is approved, we guide partners through payout destination registration and check payout eligibility based on onboarding status and account restrictions.

FAQ

Rewards are finalized at the end of the month following the end user's payment, and the payout is processed on the 25th of the following month. Bank arrival depends on the payment processor but is expected by the end of the payout month. For example, an end user's January payment is finalized end of February, processed on March 25, and expected to arrive by end of March.

Yes — $10. Rewards become payable once the accrued balance reaches $10. If the balance remains below $10 for 180 days after finalization, the unpaid amount is forfeited (a constraint under Japan's Payment Services Act).

The bank transfer fee is generally JPY 300 per payout. It is deducted from the partner reward at payout. The amount actually transferred is the reward net of the fee.

Reward amounts are calculated in US dollars (USD), but payouts are made in Japanese yen (JPY). The USD-to-JPY conversion rate is determined by the external payment processor; we cannot control when the conversion occurs.

Consumption tax included in the IrukaDark fee paid by the end user and consumption tax on rewards paid by us to the partner are separate transactions. For reward calculations, we first remove the consumption tax portion from the end user's tax-inclusive payment and calculate the tax-exclusive base reward. For example, with a tax-inclusive $9 Plus plan, 10% tax, and a 20% Bronze rate, the tax-exclusive amount is about $8.18 and the base reward is about $1.64. If the exchange rate is 1 USD = JPY 150, the base reward is about JPY 246. If the partner submits the registration number (T + 13 digits) and we can confirm the partner has an active qualified invoice issuer registration through Japan's National Tax Agency publication site or an equivalent source, we treat the reward as consideration for referral/sales support provided by the partner, add about JPY 25 in consumption tax, and record about JPY 271 as the reward. If the partner is not a qualified invoice issuer, does not submit the required registration information, or we cannot confirm an active registration, no consumption tax amount is added. Actual payout occurs after the accrued balance reaches US$10, with a JPY 300 transfer fee deducted.

Under Japan's Payment Services Act, if the accrued balance remains below $10 for 180 days after finalization, the unpaid amount is forfeited. If the balance reaches $10 within the 180-day window, it is paid out as usual.

No. IrukaDark does not withhold tax. Recipients are responsible for their own tax filings as required.

No. Self-referrals — entering your own partner code on your own account to receive rewards for yourself — are prohibited. Applying your code to other accounts (including those owned by family members, separate accounts within the same legal entity, or separate legal entities operated by the same representative) is permitted. Violations may result in reward forfeiture, suspension of partner status, and clawback of previously paid rewards.

The code can be entered, but no reward accrues during the Free period since Free is unpaid. If that user later upgrades to a paid plan (Plus / Max / Team), they become eligible for partner rewards automatically from that point.

Enterprise contracts (amount, structure, payment terms) are negotiated individually. Partner reward terms (rate, payment timing, etc.) are therefore also determined on a case-by-case basis.

Partner Program Terms

These IrukaDark Partner Program Terms (the “Partner Terms”) set out the participation requirements, referral activities, partner rewards, and related conditions for the IrukaDark Partner Program operated by Core Inc. (“we,” “us,” or “our”).

  1. Article 1 (Scope and Priority)

    • These Partner Terms apply to individuals and legal entities participating in the IrukaDark Partner Program (the “Program”).
    • A partner’s use of IrukaDark as a user remains subject to the IrukaDark Terms of Service, Privacy Policy, applicable plan terms, and other conditions specified by us. These Partner Terms govern only Program-specific matters such as partner rewards, partner codes, and referral activities.
    • If the Program description, FAQ, or other explanatory text on this page conflicts with these Partner Terms, these Partner Terms prevail. If we separately provide written individual terms or a separate agreement, those individual terms prevail.

  2. Article 2 (Eligibility and Review)

    • The Program is available only to individuals who are at least 18 years old and reside in Japan, or legal entities located in Japan.
    • Partners must provide and maintain accurate, current information required by us and by Stripe in connection with Stripe Connect, including identity verification, payout destination, and tax-related information.
    • Participation is subject to our review, Stripe’s review through Stripe Connect, and activation of the capabilities required for payouts. Partner activities may begin once screening is completed and we issue a partner code.
    • We may approve, hold, restrict, or reject any application based on screening results, submitted information, legal or payment-processor constraints, and operational needs.

  3. Article 3 (Partner Codes)

    • We issue a unique partner code to each partner. All rights in partner codes belong to us, and partners may use them only for Program purposes.
    • Partners may share their partner code through direct referrals, social media, websites, newsletters, seminars, deployment support, and similar lawful activities that comply with these Partner Terms.
    • A partner code applies when an end user or the owner of the relevant organization enters it in IrukaDark account settings or another supported flow. As a rule, only one active partner code may apply to an account or organization, and changes or removal require our approval.
    • Unless we expressly state otherwise, a partner code does not provide the end user with any discount, refund, benefit, or change to service terms.

  4. Article 4 (Eligible Rewards)

    • Partner rewards apply to Plus, Max, and Team subscription fees and additional credit purchases generated by an eligible end user or organization after a valid partner code has been applied.
    • No rewards accrue while an end user is on the Free plan. If a partner code is entered during the Free period and the user later upgrades to a paid plan, eligible paid charges after the upgrade become rewardable.
    • Enterprise plans, custom quotes, agency agreements, and other non-standard contracts are handled case by case. Reward rates, payment terms, and eligible scope are determined separately between us and the partner.
    • Unpaid charges, failed payments, refunds, cancellations, chargebacks, fraudulent use, unsupported currencies, unsupported prices or invoice items, charges that occurred before partner-code application, and other charges we determine to be ineligible do not generate rewards.
    • If plan changes, prorations, refunds, or other billing adjustments occur, the adjustment may offset the same invoice or future rewards and may reduce or cancel the reward.

  5. Article 5 (Reward Calculation)

    • Rewards are calculated from the applicable Stripe invoice line subtotal before consumption tax or similar taxes and before discounts are applied. Examples are estimates only; actual calculations are based on Stripe invoice data, rounding, exchange-rate information, and our records.
    • Rewards are calculated in US dollars (USD) and paid in Japanese yen (JPY) based on the exchange rate available through Stripe payment and payout information. Exchange rates, conversion timing, and bank arrival timing are controlled by the external payment system.
    • The reward rate is the rate assigned to the partner rank or individual agreement at the time the reward is recorded. Standard estimates are Bronze at approximately 20%, Silver at approximately 30%, and custom terms for Gold and Platinum.

  6. Article 6 (Partner Ranks)

    • We review and determine partner ranks and reward rates based on referral volume, sales results, deployment support, customer support, eligible plans, region, contract type, and other activity.
    • Rank upgrades, rank downgrades, reward-rate changes, co-marketing support, and joint enterprise proposal opportunities are provided at our discretion.
    • The Program does not guarantee any number of referrals, conversions, reward amount, recurring reward, rank upgrade, or other result.

  7. Article 7 (Reward Finalization, Payout, and Fees)

    • Partner rewards are finalized at the end of the month following the month in which the eligible end-user payment occurred. We aim to process payout on the 25th of the following month. Bank arrival may vary depending on financial institutions and payment processors.
    • Rewards become payable once the accrued amount reaches US$10. If the accrued amount remains below US$10 for 180 days after finalization, the relevant reward expires due to legal and payment-processor constraints.
    • Payouts are made through Stripe Connect. If payout information is incomplete, identity verification is incomplete, the Stripe account is restricted, legal restrictions apply, or we or the payment processor determine that payout should not proceed, we may hold, suspend, or cancel payment.
    • Fees and costs arising from Stripe Connect use, currency conversion, remittance, bank transfer, and other payment processes are generally JPY 300 per payout unless we expressly state otherwise, and are deducted from partner rewards. The amount after deduction is the amount actually transferred.

  8. Article 8 (Taxes and Invoices)

    • Consumption tax included in the IrukaDark fee paid by the end user and consumption tax on rewards paid by us to the partner are treated as separate transactions. Partner rewards are displayed and calculated as a tax-exclusive base reward. If the partner submits the registration number (T + 13 digits) and other required information, and we can confirm an active qualified invoice issuer registration through Japan's National Tax Agency publication site or an equivalent source, we add the applicable consumption tax amount to the base reward paid in Japanese yen. If the partner is not a qualified invoice issuer, does not submit the required registration information, or we cannot confirm an active registration, no consumption tax amount is added.
    • We do not withhold income tax from partner rewards. Partners are responsible for their own income tax, corporate tax, consumption tax, accounting, reporting, and payment obligations.
    • Partners must reasonably cooperate if we request documents or information needed for reward payment, tax processing, audits, identity verification, or legal compliance.

  9. Article 9 (Prohibited Activities)

    • Partners must not enter their own partner code on their own account, or on an account they substantially use, in order to receive rewards (self-referral). Referrals to family members, separate accounts within the same legal entity, or separate entities operated by the same representative are allowed, but we may treat them as violations if we determine that they are a disguised self-use or improper reward scheme.
    • Partners must not make false or misleading statements, advertise discounts, refunds, or outcome guarantees not provided by us, present themselves as our official agent, or misuse the IrukaDark brand, trademarks, or logos.
    • Partners must not engage in spam, unlawful advertising, infringement of third-party rights, improper collection of personal data, collection of end-user login or payment information, tampering with partner codes or billing information, improper creation of multiple accounts, or other abuse of the Program.
    • Partners must not, without our prior approval, make any promise, pricing condition, deployment guarantee, support guarantee, representation, or agreement that would bind us.

  10. Article 10 (Disputes with Referral Targets)

    • Partners are responsible for carrying out any checks, approvals, disclosures, or other procedures necessary for referral activity and receipt of rewards.
    • We do not warrant that a partner's referral activity or receipt of rewards is lawful or appropriate in relation to referral targets or other third parties, and we have no obligation to verify this.
    • If any dispute, claim, measure, damage, or similar matter arises between the partner and a referral target or other third party in connection with referral activity, receipt of rewards, or the Program, we are not liable except in cases of our willful misconduct or gross negligence.
    • If we incur damage, costs, claims, or other disadvantage in connection with the preceding item, the partner must compensate us for it.
    • If we reasonably determine that there has been a false statement or other clear misconduct in connection with a partner's referral activity or reward claim, we may suspend payment of the relevant reward or require repayment of rewards already paid.

  11. Article 11 (Breach, Suspension, and Termination)

    • If a partner violates these Partner Terms, the IrukaDark Terms of Service, applicable law, payment-processor terms, or our instructions, we may suspend or terminate partner status, invalidate partner codes, end referral assignments, hold or cancel rewards, require repayment of paid rewards, restrict accounts, claim damages, or take other necessary measures.
    • No new rewards accrue while partner status is suspended, restricted, or terminated. Rewards validly finalized before termination remain payable under these Partner Terms unless payment is inappropriate or impossible due to breach, fraud, refund, payment restrictions, incomplete identity verification, or similar circumstances.
    • Partners may leave the Program through the method specified by us. After withdrawal, the partner code may no longer be used and no new referrals or rewards accrue.

  12. Article 12 (Customer Information and Confidential Information)

    • Partners must handle information obtained from end users, customers, business contacts, and other third parties in accordance with law, contracts, privacy policies, and the relevant person’s consent.
    • Partners must not use or disclose non-public information received from us, end users, or third parties for purposes outside the Program.
    • Unless we expressly request otherwise, partners must not collect, store, or send us end-user authentication information, payment information, secrets, sensitive information, or other information unnecessary for referral or support.

  13. Article 13 (Independent Business)

    • Partners act as independent businesses or individuals. These Partner Terms do not create an employment, agency, joint venture, franchise, mandate, partnership, or similar relationship.
    • Partners have no authority to enter into contracts on our behalf or legally bind us.
    • Unless we separately agree in writing, partners are responsible for their own costs related to referrals, advertising, sales, deployment support, customer support, and other Program activities.

  14. Article 14 (Changes and Termination of the Program)

    • We may change the Program, eligible plans, reward rates, rank requirements, payment terms, screening criteria, features, operations, or these Partner Terms as needed.
    • Updated conditions apply from the time we announce them on this page, in the service, by email, or through another reasonable method, or from the effective time stated in the announcement. If a partner continues referral activities after the change, the partner is deemed to have accepted the updated conditions.
    • If required by law, payment-processor request, security, fraud prevention, business needs, or other urgent or reasonable circumstances, we may change, suspend, or terminate the Program without prior notice.

  15. Article 15 (Supplemental Application and Consultation)

    • Matters not covered by these Partner Terms are governed by the IrukaDark Terms of Service to the extent consistent with their nature.
    • If any question arises regarding the interpretation of these Partner Terms or the Program, we and the partner will discuss the matter in accordance with applicable law and the principle of good faith.
