Nearest OK Store

I heard that OK stores sell things at reasonable prices. If I stay in Shinjuku, where is the nearest OK store. Thank you

Do you mean Circle K convenience stores?

There aren't any of that specific brand of convenience store around Shinjuku, but their are several of their affiliate Sunkus convenience stores in the area:

Plus there are tons of other brand convenience stores around Shinjuku (7-11, Lawson's, Family Mart, etc.) that all have similar products and prices. Note that while not expensive, general goods tend to be slightly higher priced at convenience stores that at supermarkets for example. See this page for more info:

She probably means the OK supermarket.

I see, in that case the nearest one is about a 15 minute walk and train ride from Shinjuku Station. Not sure if its worth the effort though.
