This place was just great! I loved that the majority of products they carry are locally made in Japan, which most probably can't be found anywhere outside of the country. I went around lunch time and the staff was putting out boxes of meat/vegan bento, which I assumed were freshly made in the big kitchen attached to the store where they also hold cooking classes. They had a community table in case you want to dine in. There was a small fresh produce corner too but I was mainly interested in travel food.
The variety of vegan cookies was amazing. I couldn't resist and bought a couple of different flavors, including one made with Maya nuts, something I had never heard of before. I also got a loaf of vegan gluten-free bread made with just brown rice flour and no starches, which is extremely uncommon for commercial GF breads. Then there was this whole chest freezer full of vegan ice creams by the entrance. I was really intrigued by a yam-based one that claimed to be completely fat free so I got the adzuki bean flavor of that. Was actually more like a sorbet but was yummy nonetheless. I also saw some non-dairy milks that I didn't see at the other health food store I visited earlier.
The location was quite convenient, just a short walk from Shinjuku or Yoyogi station. For me it was even easier as it was literally right behind the hotel my partner and I stayed at. I just can't believe I didn't know it until the very last hours of our trip; otherwise it would have been so handy to stock up on breakfast food and travel snacks.
