The general incorporated association "Nataore no Ki," which operates on the remote island of Takaikamijima in the Seto Inland Sea, has been actively working on regional revitalization since its establishment in 2019 (Heisei 31). Currently, it runs one guesthouse and plans to add another this spring. In addition, the organization is engaged in diverse projects such as creating manga murals, operating the restaurant "Manga-tei," and hosting a manga school, all aimed at enhancing the island's appeal as a "Manga Island." This association was founded to address the crisis of Takaikamijima potentially becoming an uninhabited island. Visitors are encouraged not only to enjoy the island's tranquility and beautiful natural environment but also to feel the passion behind its revitalization efforts.

This guesthouse is particularly recommended for solo travelers and those who love exploring islands. Its exclusive location, accessible only by boat, adds to its distinctive appeal.
