About this site
Biroto (蒲葵島) is a wall dive at Kashiwajima in Otsuki, Kochi, with rugged terrain and a bold drop-off. Schools of chicken grunt and yellowstriped butterfish are joined at times by dogtooth tuna and sharks, and the dive can be shaped to suit the divers. There are three sections: Kita no Hama, No. 1 and No. 2.
