Nothing can beat USA in that too.Things I bought or considered when I went there.
.
2. Climbing gear was good price. I bought some Mammut gear but its not made in Japan. Then again its cheaper in US if you can shop there.
But It is also possible to find some great gears in Japan ebay . Even if is used.
Usually I find Japanese selling their used stuff is almost like new even if old.
Very well kept and all.
