Namerikawa is said to be the "Mecca" for finding rare deep creatures in Japan. During the month of April and May, Namerikawa is visited by the Liparis tessellatus aka. Snail fish (Japanese "Bikunin") from the depth of 249-346 m. This creature is very popular among the Japanese divers not just because of its rarity but its lovable appearance. Growing only up to 16cm, its gray soft skin and its big comical moving eyes is a sight to see. This is the only place in Japan and maybe even in the world, that you can see this rare creature during recreational scuba diving.
Also Watasenia scintillans aka. Firefly squid, sparkling enope squid (Japanese "Hotaruika") can be seen during April, when they come up from the deep to lay their eggs in the shallow waters. Sometimes, due to the tides, the firefly squids are washed onshore, making the beach light up in florescent blue, which the locals call it "Mysterious Lights of Firefly Squid". This phenomenon occurs randomly and you are considered lucky, if you can see it during your visit.
Lebbeus balssi aka. Broken-back Shrimp (Japanese "Barusui aramo shrimp"), often referred to as a "Queen of the Shrimp world” in Japan, for its beautiful appearance is another idol you want to challenge. This shrimp is normally found in waters deeper than 55m but are found in depths around 22m around these waters. A big bonus for visiting divers. There are also the super macro angels between the seaweeds.
Aptocyclus ventricosus aka. Smooth lump sucker (Japanese "Hoteiuo"), Lethotremus awae aka. Japanese "Dangouo", Liparis punctatus aka. Japanese "Sunabikunin". These babies are all 1-2mm in size, but if you’re an underwater photographer with the right lens, you can catch the beautiful patterns of colors on these tiny angels. It will be an experience you will never forget.
A beach point with only 5m maximum depth, this spot is popular among the nudibranch fans in this area. The best seasons are from November to June when the water temperature drops. You can also enjoy the summer season as there are seahorses in this area as well.
