Japanese Commercial Disclosure and B2B Transaction Information
Revised September 25, 2026. The effective date is displayed on the publication screen presenting this version.
1. Service and contracting parties
This disclosure describes the business platform service provided by Rubik KK (Japanese name: ルービック株式会社; “Rubik”) and its transaction conditions. The Seller of goods is the business identified on the offer/order screen. Rubik's platform agreement and the sale between Seller and Buyer are separate contracts.
The service is for business transactions; this does not mean consumer distance-selling provisions apply uniformly to every transaction. Application of Japan's Act on Specified Commercial Transactions and other laws depends on the actual purpose, content, counterparty and destination. A business declaration alone does not remove applicable mandatory rights.
If Rubik itself sells goods, it is identified as Seller on the order screen and bears the Seller's obligations for that sale. An affiliated company selling goods is identified in its own name. This operator disclosure does not replace every disclosure required of an individual Seller.

3. Service fees and displayed prices
There is no registration fee or ordinary monthly subscription. Offra's base commission is 6.4% of the Buyer-facing goods-price basis identified for commission calculation. No Offra commission applies to shipping. This is not simply 6.4% of the Seller's desired receipt. Card-processing costs and tax follow the provider's applicable conditions; a stated 3.6% rate alone does not establish the full cost including tax.
Quotation and acceptance screens show goods, shipping, the Buyer's total JPY charge and expected Seller receipt. For a transaction performed normally, the agreed Seller receipt is maintained; Rubik adjusts ordinary processing-cost/tax estimation differences. A different allocation for future specified transactions requires clear advance terms and the Seller's separate express agreement. Refund, chargeback and related adjustments follow Articles 5, 8 and 10 of the Terms.
The Buyer is charged in Japanese yen (JPY), without an unagreed increase after acceptance. EUR and other conversions are indicative. The card issuer's conversion and processing time may cause actual debits and refunds to differ.
4. Additional costs and taxes
Shipping is quoted before acceptance and included in the charged total. Customs duties, import VAT, clearance charges and card-issuer costs are additional unless expressly included. Import taxes and costs are normally borne by the Buyer and depend on destination, goods and import conditions. Japan's export tax exemption requires the relevant statutory conditions and evidence; it does not make every transaction unconditionally tax-free.
5. Formation, payment method and timing
Acceptance of an offer creates the sale between the identified Seller and Buyer. Within 48 hours, the Buyer must complete the specified card or other payment steps through Stripe. Incomplete orders are subject to cancellation.
Card authorisation reserves credit. Registration of a valid tracking number by the Seller triggers capture. Authorisation, capture, payment balance, payout and bank credit are distinct states; authorisation or tracking registration alone does not guarantee successful payment.
The ordinary payout hold is released after the initial 48-hour claim period following confirmed delivery ends without a claim. Fraud, payment disputes and other reasonable grounds under Article 6 of the Terms may justify a continuing hold. Passage of time alone does not establish delivery. Holds operate within payment-contract and legal limits and are not indefinite. Bank credit depends on Stripe's fund availability, account status, payout schedule, bank business days and other relevant factors.
6. Service availability, dispatch and delivery
Platform functions become available after registration approval and other required steps shown on screen. Unless expressly agreed otherwise, the Seller dispatches from Japan within 5 business days, counted from the day after card authorisation and excluding Saturdays, Sundays and Japanese public holidays. If authorisation expires sooner, reauthorisation or other action follows Article 6 of the Terms. Transit time depends on the delivery method, destination and customs clearance. The Seller checks the agreed tracked method and suitable coverage and communicates tracking information.
7. Cancellation, returns and refunds
Ordinary discrepancies, damage or missing goods should be reported within 48 hours of confirmed delivery, with photographs or other reasonably obtainable evidence. For non-delivery, the post-delivery period does not begin; where photographs cannot be obtained, provide the reason and other evidence. Non-delivery exceeding 21 days after dispatch is investigated; earlier reports are possible where reasonable circumstances indicate loss or a similar problem.
The 48-hour period governs initial review and the ordinary hold; it is not a limitation period extinguishing statutory or card-scheme rights. Fraud, counterfeits, stolen goods and payment disputes may be investigated later. Rubik considers both parties' explanations and evidence and gives reasons for platform measures. Internal reconsideration may be requested within 7 calendar days of notice, without preventing judicial remedies.
Cancellation, returns and full or partial refunds follow Article 8 of the Terms, the seriousness of the problem, the parties' agreement and applicable law. Return costs attributable to the Seller are borne by the Seller. Buyer-convenience withdrawal is not automatic and depends on individual agreement or applicable law. Rubik is not an unconditional guarantor of the goods price, nor does it disclaim its own statutory or individually agreed obligations.
Refunds are normally in JPY to the original card. Offra commission is reconciled according to the JPY refund proportion, previous fee returns and cost adjustments. Article 8 governs costs not returned by the provider; they are not automatically deducted from a Buyer's legitimate full refund.
8. Validity, limits and related documents
Requests run for 7 to 30 days, with the deadline shown on screen. Offer acceptance deadlines, exclusive negotiation, intake limits, expiry and reposting follow the relevant screen conditions and Terms. Cancelled or expired offers cannot be accepted.
This disclosure explains transaction information and is not an independent guarantee expanding the allocation of responsibility in the Terms. See the Seller Terms, Buyer Terms, Seller Privacy Policy and Buyer Privacy Policy. The three language versions establish the same substance; the reference language and reservations for mandatory law and other protected rights follow Article 16 of the Terms.
