The “Vegetarian” Fresh Juice Bar located in the New Shimbashi building 1st floor, has been in business for 40 years. It is worth a visit if you are in the area (Shimbashi station is just south of Tokyo station on the Yamanote line.)
Vegetarian juice bar has various types of juice, but everything is in Japanese, so you would be well served with some ability in it, or to bring a friend to help. Prices are reasonable at 300 to 700 JPY, with egg or veg-fruit sandwiches available cheaply for juice customers.
Example juices -
“Hard” Veg ハード野菜
… and various others. Most of the juices have a bit of fruit in them, and they seem to be putting red grapefruit in with the parsley and kale juice. The “hard” yasai is 7 types of veg mixed together, and is veg only, and “harder to drink” according to the hardworking ladies of Vegetarian.
