Legal identity
Kabushiki Kaisha FermionTrading as: InshiHub
Company-published business address: 8F MIEUX Shibuya Building, 5-3 Maruyamacho, Shibuya-ku, Tokyo 150-0044, Japan
Country of incorporation: Japan
Japanese Corporate Number: 1011001179318
Website: https://in.inshihub.com
"Kabushiki Kaisha Fermion" is the Roman-script presentation of the company's Japanese legal name; no translated English legal name is asserted. A company record with the corporate number and Tokyo address shown above is published by Japan's National Tax Agency. This 13-digit Japanese Corporate Number identifies Fermion in Japan. This publication does not establish that Fermion has an Indian GSTIN, PAN, foreign-company registration, Dodo transaction-seller registration, or any particular tax status. The Corporate Number is not presented here as a GST registration or tax-invoice registration number; any applicable invoice or tax registration must be disclosed separately.
Representative and customer care
Representative: Takumi Kokawa, Representative DirectorCustomer-care email: contact@fermion.company
Customer-care telephone: not yet available
Fax: not available
Fermion has not yet published a customer-care telephone number. Checkout will remain disabled until the applicable Dodo transaction seller and every required India-facing customer-care channel are confirmed and displayed.
Interim grievance contact; formal designation pending
Takumi Kokawa, Representative Director; proposed interim escalation contactEmail: contact@fermion.company
Postal address: 8F MIEUX Shibuya Building, 5-3 Maruyamacho, Shibuya-ku, Tokyo 150-0044, Japan
Telephone: not yet available
A formal India-facing Grievance Officer designation is not asserted. The named representative is shown only as the proposed interim escalation contact while the required corporate designation, telephone channel, and India-specific arrangements are completed.
Current website and product-support complaints will be acknowledged within 48 hours and addressed within one month under the grievance redressal process. Transaction grievances will also require the Dodo contact identified in checkout and receipt materials. The exact allocation remains a precondition to opening checkout.
India-resident nodal contact and company registration
India-resident nodal officer: Fermion has not appointed an India-resident nodal officer. The proposed Dodo reseller structure is not treated as eliminating any requirement; the entity responsible for each India-facing role is under written review.
Indian foreign-company and local service-agent status: Fermion has no India branch or local service-agent address. The application of foreign-company, registration, local-presence, and service-agent requirements to Fermion and the proposed Dodo reseller structure remains under written review.
The applicable Companies Act definition and foreign-company rules can include business carried on through electronic mode, including business-to-consumer digital supply, web marketing, transactional services, online education, and information services. Because this site specifically serves India, Fermion is obtaining a written Indian corporate-law classification rather than assuming that the absence of an employee, office, or server in India settles the question.
Fermion proposes to supply the product from Japan to Dodo for resale. We are obtaining written confirmation of the Dodo entity that would sell to Indian buyers and which entity owns each India-facing customer-care, grievance, nodal, tax, invoicing, and registration obligation. The proposed reseller structure is not treated as eliminating any requirement. Checkout remains disabled until that allocation is confirmed and every required contact is displayed.
Website operator, product supplier, and transaction seller
Kabushiki Kaisha Fermion, trading as InshiHub, operates this website and creates, supplies, licenses, and supports InshiHub products. If checkout opens and Dodo Payments approves and processes an order, the exact Dodo Payments group entity disclosed at checkout and on the invoice, and confirmed in the applicable transaction documents, will act as the authorised reseller, merchant of record, and transaction seller. Dodo's current generic public Buyer Terms do not identify that exact entity. The buyer will purchase from the identified Dodo entity only after that identity and allocation are confirmed.
Fermion will remain responsible for product rights, description, quality, corrections, licence content, and product-level support. Subject to the executed reseller arrangement and mandatory law, the identified Dodo entity is expected to handle the resale transaction, payment collection, transaction receipt or invoice, transaction-level payment support, fraud and dispute handling, transaction-refund execution, and applicable indirect-tax functions. Its current Buyer Terms describe those functions in general but do not resolve the exact India entity or every responsibility conflict. Checkout remains disabled until they are resolved.

The linked route for each edition is the authoritative source for its exact scope, samples, exclusions, price, correction status, and availability. Figures from one edition do not apply to another.
No listed checkout offer is active or available for purchase. If sales open for an edition, the Dodo checkout can be configured to show that edition's final total, applicable tax treatment, and any mandatory currency or payment charge before the customer takes an affirmative payment action, subject to merchant approval and live verification.
Cross-border supply, tax, and importer status
Fermion would supply or license the product from Japan to Dodo for resale. The Dodo entity identified at checkout would resell it to the Indian buyer. Dodo is expected to handle buyer-facing transaction invoicing and applicable indirect tax in its reseller capacity; Fermion retains its own supplier-side Japanese and cross-border obligations.
We will not claim that Dodo removes every Indian registration, local-presence, grievance, or tax requirement until the allocation is confirmed in writing.
