Most of the Japanese brands are hard to get outside Japan, and flying to Tokyo is often the best way to get one, otherwise you're stuck with buying online but you have to know well what you're doing because Japanese denim is almost always unwashed, meaning it will shrink after use so you really have to know how much higher a size to order so that it will fit you well after 6 months.
