Hotel K5

The man whose bank built this place is on the ¥10,000 note. Shibusawa Eiichi founded the First National Bank of Japan, and in 1923 it put up an annex behind the Tokyo Stock Exchange, in a district once called Japan's Wall Street. Kabutocho went quiet after 1990, when trading no longer needed a floor, and the annex was due for demolition until Heiwa Real Estate, which owns the exchange, made it a hotel of 20 rooms in 2020. Claesson Koivisto Rune, from Stockholm, kept the vault doors and the oak parquet and worked to aimai, the Japanese taste for spaces that run into one another. Upstairs, curtains do much of the walls' work: indigo, dip-dyed so the blue drains to white near the floor, and drawn round beds under paper lanterns. Even the cracks were kept, filled with gold lacquer in the kintsugi manner, so there is gold in the bank again, if not in the vault.

Recommended for grown-ups who want the neighbourhood downstairs. The ground floor and basement are let to restaurants and bars that draw Tokyo as well as guests: Chihiro Maruyama cooks Japanese-Nordic dinners at Maruyama, and the basement belongs to B by The Brooklyn Brewery, its first flagship outside the United States. Nihonbashi Bridge is six minutes' walk, Ginza fifteen, and there are bikes for further. Every room has a record player and only the suites a bath, so book the High Ceiling Junior Suite, which has the bath and the extra height. Nihonbashi also has Fukutoku Shrine, licensed to hold lotteries in the Edo period, where people still pray for a winning ticket: the neighbourhood's other way of getting rich, and the quicker one, when it works.
