This supermarket is nice, but really expensive and does not have so many vegan foods. In fact, there are way too much meat and dairy.
However, their deli dishes are really affordable. They have several kinds of bento, soups and a curry that are labelled 'for vegetarian'. They also have several kinds of fresh vegetables. I had a bento with a chunk of tempura and rice, only 500yen. This bento is vegan, but I am not sure whether other 'for vegetarian' bentos are vegan..
If you come later in the afternoon, most of the deli food might be gone. I came at 6pm and there wasn't much left.
You can eat in or take out. There is a microwave to heat your food.
All in all, it's nothing too special, but I am always happy to find vegan food in Japan and the prices of the deli are really OK.Pros: The deli is good value for money, Eat in or take out, Vegan dishes in the deli!
Cons: The supermarket is expensive, Not many vegan foods in the supermarket, No ingredients in English
