I havent been able to find much for straight razors here in japan, there is a cutlery shop in ginza i received my japanese style razor from. if you would like their details i have hook you up. they have a wonderful section of knifes also. they also have a few brushes, safety razors and misc male grooming products. there are also a few stores that have some shaving supplies(creams, aftershaves and safety razor blades. send me a message if you would like to know some into, cheers!
