Peak summer in Tokyo’s relentless, punishing heat island. When energy levels flag and appetites shrivel, it pays to know where to refresh, rehydrate and find sustenance in the city.

In the heart of Nihonbashi, the newly opened Heiwa Doburoku Kabutocho Brewery makes for a welcome oasis.

Set up by Heiwa Shuzo, an enterprising sake producer based in Wakayama Prefecture, it is both a brewpub and a bottle shop, one of the very few in the city that specialize in the thick, creamy white, mildly alcoholic beverage known as doburoku.
