Where to find Japanese groceries

This post is a work in progress. Am I missing something? Let me know at keiko dot in dot boston [at] gmail dot com!

We have just one remaining exclusively Japanese grocery store in all of New England, but there are many other places to buy Japanese groceries in the Greater Boston area which may be more conveniently located for you and may have better prices. Selection at some of these stores is quite limited, but many of them have staples & snacks.

In addition to Sakanaya (See Other Japanese Food Businesses), I'm told that these fish markets are popular with Japanese folks.

American Grocery Stores

Many Shaw's and Stop & Shop locations have a small section of their international aisle dedicated to Japanese food. It tends to be limited to packaged food and snacks.

Whole Foods Market carries American brand "Japanese" food such as Eden Foods, Great Eastern Sun, and South River Miso Company.
