Shops in Europe selling Japanese food

There are some shops selling Japanese items to eat and cook online. Note that they deliver only to restricted areas, like within the country.

smartdeli in Germany

Hokkai suisan in Netherlands

Nishi in Zurich, Switzerland

(This picture has nothing to do with the shops above. Just to inspire you!)

There should be more shops, but I just listed some I know and sometimes rely on. They should be already famous among Japanese people in those areas, but not so well-known among local European people as I thought.
