I have been ordering my Japanese green teas from O-cha.com for years now, they're my trusted source for Japanese green tea. Their senchas and matchas are excellent value and there are a lot to choose from so you'll find your favorite. Shipping is fast, it took around a week to arrive so you don't have to wait long to get your washi cans full again. Long story short: if you order, you won't be disappointed on tea or the service.
