I could only find Korean soba noodles at the Asian supermarket but I ordered wasabi powder off Amazon and I think it turned out similar to how you get it in Japan. I made the tempura bits and dashi for the tsuyu myself which isn’t too hard but I’m proud of how it turned out. I didn’t try it because I’m watching my sodium and sugar but hopefully my mom got a somewhat accurate first impression of cold soba.
