Fly fishing stores and unique things to buy in Japan?

[Robert]

I’m travelling to Japan in April and will be in:
Tokyo
Hakone
Gotemba
Fujikawaguchiko
Kyoto
Hiroshima
Osaka
and was looking for any recommended fly fishing stores in any of these locations (the bigger the better) and in particular any japan-only interesting or unique fly fishing curios and equipment that are worth checking out?
