I had the pleasure of live in Japan for 11 years, that said, I need to say I never went to Ikehara Dam because of the distance and lack of money Ikehara Dam have monster bass and another great and beautiful place close by is Nanairo Dam, one of the most beautiful fishing places I ever seen in Japan (in videos ). If you want to see some monsters from Ikehara Dam, check out videos with Murata Hajime or Toshifumi Kikumoto, also Deps use do film there too.
