Namerikawa shore dive with deep-water surprises.
Namerikawa shore dive with deep-water surprises.
A local guide is the practical baseline for timing, entry windows, and seasonal conditions.
Namerikawa is a Toyama Bay shore dive known for cold-water wildlife and after-dark diving. The entry starts on a gravel beach, crosses rounded stones, and opens onto sand with man-made structures offshore. The profile deepens steadily as you move out, so it suits divers who are comfortable managing buoyancy, navigation, and changing bay conditions. Seasonal highlights include firefly squid and other rare deep-water visitors that make repeat visits worthwhile.

Scuba Diving
Shore diving with a shallow start and a longer offshore profile; best for controlled exploration and night sessions.
Freediving
Possible only in the shallow entry zone; the site's main draw is farther out and is better suited to scuba.
Snorkeling
Snorkeling is limited to the shallow edge and is more of a look at the entry than a full site experience.
