Living up to its name, this really is a box - it looks like a shipping container, with rather minimalist decor and furnishings, and standing areas inside and outside. They serve four different craft beers fresh from Brimmer Brewery in Kanagawa Prefecture - golden ale, pale ale, porter and ESB the last time we dropped by - for Y500 a glass. There's no food, but you can find good take-out fried chicken at the shipping container next door. Open from noon on weekends.
