Having moved to Tsukuba to start uni this year I was struggling to find a place selling healthy vegetarian/vegan food or products. Having lived in Australia and the UK previously and being spoiled for choice in terms of vegetarian food, Tsukuba was a wasteland offering only the typical family food chains or meat/fish containing Japanese type restaurants.
Finding Ritzn was a breath of fresh air and a relief. They offer a menu of non-meat dishes, including an incredibly tasty non-meat burger that I could easily see myself eating almost every day if I was able to get there easily. Other dishes include pasta with a 'meaty' sauce, as well as Japanese style dishes all vegan, and all tasty.
There is also a small variety of groceries available including items that are impossible to find elsewhere within Tsukuba city as well as fresh local organic fruit and vegetables from nearby farmers which are all far superior to the normal selection available in supermarkets. There are also organic and natural cosmetics and other products. All in all the attached store is very quaint and has some really interesting bits and pieces.
If it wasn't so difficult to get to by any means other than car I could see myself eating here 2 or 3 times a week and I can't recommend Ritzn highly enough, not only for vegetarians and vegans but for anyone who appreciates great food made with high quality organic ingredients.

Cons: slightly expensive, hard to reach other than by car
