It's not online AFAIK, but if you're in Osaka Hero Gangu is worth a look. A tad pricey though - Mandarake and Jungle are better for bargains, but Hero Gangu has an amazing range.
Maybe you can try buying at moon-base.jp (3rd party & official stuffs) nonstop.co.jp (3rd party & official stuffs) Red mercury.co.jp (official stuffs) Mandarake (some 3rd party & official secondhand stuffs) Surugaya (some 3rd party & official secondhand stuffs) jungle-scs.co.jp (some 3rd party & official secondhand stuffs) Hope this helps, I been staying Japan for 3 years but recently went back to my home country due to the pandemic.
Anyone in the US ever return anything to Amazon Japan? Is it like Amazon US where you get free return shipping? I bought a Switch game (Darius Cozmic Revelation) and now want to return it and buy a western version instead as it has an extra game.
