Nishikawana
★★★★☆
(101)
This spot is located at the tip of Tateyama on the Boso Peninsula. Boat diving only, with a maximum depth of 25m and an average of 15-16m, the bottom of the water is a mix of rocky reefs, gorota stones, and sandy terrain. Caution is needed as the flow can sometimes be fast.
Around the V-shaped valley, you can see big fish such as Kue, schools of sunfish, and damselfish. Stingrays can be seen in schools in the summer. Also, a huge black sea eel has taken up residence here and can be observed up close. In the summer, we often encounter schools of large migratory fish that have been chasing schools of small fish.
