Koku launches English booking platform for Tokyo’s Izu Islands

Koku Inc. launched Tokyo Islands Explorer on July 9, 2026, an English-language booking platform that bundles lodging, inter-island transport and activities across Tokyo’s Izu Islands. The rollout aims to make the remote volcanic archipelago easier to sell to international travelers and travel agencies.

Why it matters: - Tokyo Islands Explorer turns a previously fragmented, Japanese-only booking process into a single English-language platform for the Izu Islands. - The launch could open a hard-to-book remote destination to more overseas travelers and travel agencies. - The platform also supports Tokyo’s remote-island tourism strategy after selection for the Tokyo Takarajima Challenge Project.

What happened: - Koku Inc. announced the official launch of Tokyo Islands Explorer on July 9, 2026. - The platform packages accommodation, inter-island transport and on-island activities for Tokyo’s Izu Islands. - Koku Inc. says the service is available in English now, with Traditional Chinese and additional language support in development. - The rollout begins with Oshima, Toshima, Niijima, Shikinejima and Kozushima.

The details: - The Izu Islands are a chain of nine volcanic islands near central Tokyo. - Travelers can reach the islands in about 30 minutes by air or about one hour and 45 minutes by high-speed jet ferry. - Oshima and Toshima feature volcanic landscapes, Mt. Mihara trekking paths and camellia forests. - Niijima and Shikinejima offer white-sand beaches, coastal cliffs, surf spots, scuba diving sites and seaside hot springs where swimwear is permitted. - Kozushima and other islands are known for clear waters, fishing-village culture and dark skies for stargazing. - Ferry routes support island hopping across the archipelago. - Helicopter transfers are available between selected islands. - The platform includes combined accommodation and ferry packages. - Travelers can book guided diving, trekking and crafts through the platform. - The service includes booking support, customer service and international credit-card payment for overseas travelers. - Koku Inc. is operating the platform with regional transport operators such as Tokai Kisen Co., Ltd. and local island municipalities. - The company says it functions as a localized ground operator for the region.

Between the lines: - The launch addresses a core market problem: the destination existed, but the logistics kept it out of international itineraries. - Koku Inc. has spent years building the infrastructure behind the launch, including the Tokyo Islands media platform in 2014 and Tokai Kisen’s multilingual ferry-ticketing system in 2016. - Over the past year, Koku Inc. says it helped more than 2,000 international travelers visit the islands. - The company is positioning the platform for both direct booking and B2B sales, which suggests an attempt to build demand through agencies and consumers at the same time. - Eibu Sato said travel agencies are invited to co-create tailored packages and visit the islands through familiarization trips.

What's next: - Koku Inc. plans to add more language support and expand island coverage beyond the initial five islands. - The company is seeking long-term partnerships with international travel agencies for co-branded and tailor-made packages. - Familiarization trips for product managers are part of the partnership push. - The Tokyo Metropolitan Government-backed sustainability program may give the project more visibility as it scales.

The bottom line: - Tokyo Islands Explorer is an attempt to make Tokyo’s remote volcanic islands bookable for the international market by removing the biggest barrier: complicated logistics.
