Koto

Koto is a city in the Tokyo region of Japan. It has limited diving relevance locally, with no coastal access or major dive sites in the city itself. Nearby freshwater options exist at Lake Hinuma in the broader region, which can offer training or day trips for divers seeking freshwater diving experiences outside the city. As a gateway, Koto benefits from proximity to Tokyo’s larger dive hubs and international flight access, making it a practical base for divers visiting the area who plan trips to nearby coastal sites or freshwater quarries further afield.
