There are a lot of Hikawa Shrines in Japan, I lived near 氷川神社 in Nakano, Tokyo. The shrine is about two minutes from Numabukuro Station on the Seibu-Shinjuku line (local). It can be seen from the train if you pass Numabukuro towards Takadanobaba/Shinjuku.
I don't think this shrine is very important. Just that it's near the place where I've been living so long made it important to me though.
