I'm leaving Saturday for nearly 3 weeks in Japan (Tokyo, Osaka, & Kyoto). I'd like to pick up a new blade when I'm there, but honestly don't know where to start. Have any of you made the trip before and have suggestions from your experience? I'd love to get a lesser known blade (in the US) that is unavailable here. I'll probably be mailing whatever I buy home since I'm not checking my bags. I use my 240 & 270 gyutos exclusively these days. So I'll probably buy another since I want a knife I'll use.
