Japanese bookstores in Boston?

Long story short - I need to find Japanese bookstores in Boston. I know Kinokuniya is not in Boston (closest would probably be NYC). I know there is a huge Chinatown there but I don't know if their Chinatown is like the Seattle Chinatown which has many Japanese stores (including Kinokuniya).

The only one I know of close to Boston is Sasuga, in Waltham: http://www.sasugabooks.com/

They're only open on Saturdays, but you can get magazine subscriptions from them. I used to get Terebi Magazine and Uchusen before coming here.

Anyone familiar with the Palisades in West Nyack, NY? It's closer to Boston then the New York City store.
