    About .otsuka domain

    .otsuka is a brand TLD (dotBrand gTLD) that was applied for during ICANN's 2012 New gTLD Program round. The registry operator is Otsuka Holdings Co., Ltd., which signed a Registry Agreement with ICANN on October 10, 2013, after passing the Initial Evaluation. The extension was delegated to the Root Zone of the DNS on August 27, 2014. Its primary purpose is to serve as the official, unified domain extension for Otsuka Holdings and its affiliated corporate entities, consolidating web presence that was previously spread across multiple gTLDs and ccTLDs.

    Who can register .otsuka domain

    Registration of .otsuka domains is strictly restricted and is not open to the general public. Only the following organizations are eligible to register:

    • Otsuka Holdings Co., Ltd. itself
    • Companies listed on the asset securities reports of Otsuka Holdings Co., Ltd.
    • Unconsolidated subsidiaries of Otsuka Holdings Co., Ltd.
    • Affiliate companies of Otsuka Holdings Co., Ltd.

    Individual registrations are explicitly prohibited — board members, employees, and contract staff of eligible companies may not register .otsuka domains in their own name.

    How to register .otsuka domain

    .otsuka is a closed brand TLD operated exclusively by Otsuka Holdings Co., Ltd. and its designated corporate affiliates. Domain names under this extension are not available through commercial registrars and cannot be purchased by the public. Allocation of .otsuka domains is managed internally by the registry operator according to its own policies and eligibility criteria. Any entity seeking to use a .otsuka domain would need to be a qualifying subsidiary or affiliate of Otsuka Holdings and coordinate directly with the registry.

    Typical uses of .otsuka domain

    .otsuka domains are used exclusively within the Otsuka Holdings corporate family to create a unified, authoritative web presence. The extension allows Otsuka Holdings and its subsidiaries to migrate away from a fragmented collection of registrations under generic and country-code TLDs into a single, clearly branded namespace. This makes it straightforward for internet users to identify official company websites and distinguish them from unauthorized or infringing sites. The TLD also simplifies internal domain management by bringing all corporate web properties under one consistent set of registration rules and systems.

    Tips for registering .otsuka domain

    • Because .otsuka is a closed brand TLD, it is not available for purchase through any commercial registrar — do not expect to find it listed on standard domain registration platforms.
    • Registration is limited strictly to corporate entities within the Otsuka Holdings group structure; no individual-basis registrations are permitted under any circumstances.
    • The extension was designed in part as a trademark protection tool, so domain names under .otsuka carry an implicit signal of authenticity and official affiliation with the Otsuka Holdings corporate group.
    • Domain management policies, renewal terms, and operational rules are governed entirely by the registry operator rather than by standard registrar agreements, meaning external registrant protections (such as typical grace or redemption periods) may differ from those of public TLDs.

    Frequently asked questions about .otsuka domain

    Who operates .otsuka domain?The registry for .otsuka domains is Otsuka Holdings, administered by Otsuka Holdings Co., Ltd..
    Who can register a .otsuka domain?

    Eligibility is limited to Otsuka Holdings Co., Ltd. and entities directly affiliated with it, including companies appearing on its asset securities reports, unconsolidated subsidiaries, and affiliate companies. Individuals — even those employed by or serving on the board of an eligible company — are explicitly barred from registering .otsuka domains in their own name. There is no public application process, and eligibility is determined by the registry operator based on the corporate relationship to Otsuka Holdings.

    Can I transfer a .otsuka domain between registrars?

    Because .otsuka is a closed brand TLD operated by a single corporate registry, inter-registrar transfers in the conventional sense do not apply. Domain names under this extension are not registered through competing commercial registrars, so there is no standard transfer process between registrars as exists for public TLDs. Any changes to domain management or assignment within the .otsuka namespace would be handled internally by Otsuka Holdings Co., Ltd. according to its own registry policies.

    Can members of the public register a .otsuka domain?

    No. .otsuka is a closed brand TLD and is entirely unavailable to the general public, independent businesses, or individuals. It exists solely to serve the internal branding and web management needs of the Otsuka Holdings corporate group. Searching for .otsuka domains on commercial registrar platforms will not yield any registrable results.

    What dispute resolution policies apply to .otsuka?

    As a brand TLD operating under ICANN's New gTLD Program, .otsuka is subject to ICANN's standard dispute resolution framework, including the Uniform Domain-Name Dispute-Resolution Policy (UDRP) and the Uniform Rapid Suspension (URS) system. However, because registrations are restricted to affiliated corporate entities and no public registrations are permitted, the practical likelihood of third-party trademark disputes arising under this extension is very low. The closed nature of the registry itself functions as a structural trademark protection mechanism.

    Why did Otsuka Holdings apply for its own TLD instead of using existing extensions?

    Otsuka Holdings applied for .otsuka primarily to address confusion caused by the proliferation of domain names across many different gTLDs and ccTLDs, some of which were held by infringing third parties. By establishing .otsuka as the single authoritative extension for the company, internet users can more easily identify genuine corporate websites. Additionally, consolidating domain management under one registry simplifies administrative overhead and reduces the complexity of operating under many different registration systems simultaneously.
