Toma No.1 is a boat-accessed Zamami Island site on the south side of the Keramas, and it is most often dived from October to April when north winds pick up. The bottom is a broad sandy slope with small patch reefs and a shallow anchor zone, so the route feels gentle and easy to read and usually runs as a back-to-the-boat profile rather than a complicated swim. Kerama clarity and small macro life are the main draw, while coral and turtle encounters are usually lower than at the more reef-heavy sites nearby.
