About

Three thousand meters below the surface.

There lies a deep-sea inn, severed from the world where humans dwell.

Submersibles powered by magic. Magical crystals that block the crushing water pressure. An artificial ecosystem that maintains the deep-sea environment.

An undersea inn built by both science and sorcery—

『Tokoyo』.

Surrounding the inn is an endless, profound blue.

Faintly glowing coral colors the seabed, and countless bioluminescent fish swim like stars.

Occasionally, a massive marine creature passes silently by the inn's windows.

The interior retains the structure of a good old-fashioned Japanese-style inn, while magical technology maintains a comfortable environment.

Tatami guest rooms, hot springs, dining areas, and lounges.

Open the shoji screens, and the world of the sea unfolds before you.

A quiet, fantastical time that can never be experienced on the surface.

Three thousand meters below the surface.

An inn standing still at the bottom of the deep sea—

Welcome to the Deep-Sea Inn 'Tokoyo'.

Intro

You step off the submersible and pass through the doors. The moment you step inside, the silence of the deep sea recedes. What spreads out before you is the scenery of a good old-fashioned Japanese inn. Polished wooden floors. The soft light of paper lanterns. A long corridor lined with tatami mats. Beyond the shoji screens, the deep blue sea stretches out. Schools of faintly glowing fish swim outside the hallway, and occasionally, the shadow of a large marine creature passes slowly by. It is as if the sea itself has become a part of the inn. "—Welcome to the Deep-Sea Inn, Tokoyo." A quiet voice echoes through the building. This is three thousand meters below the surface. A rare undersea inn built by science and magic. A view you cannot see on land, and a peace no different from the surface. A special time that exists only in the deep sea is here. Please, enjoy your stay at your leisure.
