Description

You will read almost everywhere that thirty-three fishermen saved Tokugawa Ieyasu during his flight after the Honno-ji Incident and were handed an island. Nearly every clause of that is wrong. The debt was real, but the shrine's own tradition puts it in 1586, on an ordinary day: Ieyasu was travelling in Settsu to pay respects at a mausoleum, the Kanzaki river had no bridge, and a village headman called in his fishermen and their boats and ferried the party across. That favour is the origin of everything on this walk. In 1590 the fishermen followed him to Edo. The exclusive rights to fish the bay came later, in 1613, and no shogun handed anyone an island: they were given permission to make one out of tidal flats, and then spent more than a decade making it, naming it after the village they had left. The walk starts on a small red bridge where the whole thing is visible at once — wooden houses and moored boats in front, 1980s towers behind — and takes in the shrine they founded in 1646, a shop simmering surplus catch in soy on the same ground since 1837, and the waterfront where Perry's arrival turned a fishing island into a shipyard. Then one bridge over to Tsukishima, a nineteenth-century island where the same instinct turned a children's snack into a street of eighty restaurants. It ends on a 1940 bascule bridge built as the gateway to a World Exposition that was postponed into oblivion as the country went to war.

Highlights

The founding story told straight, against the compressed version on every plaque Sumiyoshi Shrine, founded 1646 by transplanted Settsu fishermen, and its ceramic name plaque glazed so the salt could not eat it Why an island of fishermen is named with the word for a cultivated field Ten'yasu, simmering tsukudani on this ground since 1837 — and how one island's name became a food sold across Japan The shipyard the shogunate ordered in 1853 with Perry's fleet in the bay, and the 1876 refounding the monument actually commemorates Monja Street: a cheap flour-batter snack sold to children, now eighty-odd restaurants Kachidoki-bashi, whose leaves last lifted for a ship in the late 1960s and have not moved since a test run in 1970

Tour Stops

Tsukuda Kobashi
1

Tsukuda Kobashi

5 min

Tsukuda Kobashi is a small vermilion bridge over Tsukudabori, the boat basin at the heart of Tsukuda; the present span dates from 1984, though a crossing has stood on roughly this line since the island was completed in the 1640s. From the middle of it you see moored boats and low tiled roofs in front and the towers of Okawabata River City 21 directly behind.

Sumiyoshi Shrine, Tsukuda
2

Sumiyoshi Shrine, Tsukuda

5 min

Sumiyoshi Shrine was founded in 1646 as a branch of the home shrine of the fishermen from Tsukuda village in Settsu, who had followed Tokugawa Ieyasu to Edo in 1590 and then spent more than a decade building this island out of tidal flats. Its ceramic name plaque, its stone lanterns and its 986 surviving documents are the community's own proof that Tsukuda was a relocated village rather than simply reclaimed mud.

Ten'yasu tsukudani shop

Ten'yasu tsukudani shop

5 min

Ten'yasu, trading at 1-3-14 Tsukuda since 1837, is the oldest of the island's three surviving tsukudani makers, still simmering baby fish, clams and kelp in soy sauce, mirin and sugar and selling them by weight from a wooden shopfront. Tsukudani began here as a way to stop a fishing village's unsellable surplus catch from spoiling, and the word is now used across Japan for the method rather than the place.

Ishikawajima Shipyard Monument, Tsukuda Park

Ishikawajima Shipyard Monument, Tsukuda Park

5 min

A riverside monument in Ishikawajima Park marks the spot where, in 1853, the shogunate ordered the Mito domain to build Japan's first Western-style shipyard as Perry's fleet sat in the bay. Refounded as a private yard in 1876, it grew into today's IHI Corporation, and its 103-year-old works closed in 1979 to make way for the towers behind you.

Tsukuda riverside terrace

Tsukuda riverside terrace

5 min

A short viewpoint stop on the Sumida embankment walkway in Tsukuda, where the wooden village, the cable-stayed Chuo-Ohashi bridge of 1993 and the Okawabata River City 21 towers line up in a single sightline. The terrace itself is the top of a flood defence, built to replace the concrete sea walls that once cut the island off from its river.

Tsukishima Nishinaka-dori (Monja Street)
6

Tsukishima Nishinaka-dori (Monja Street)

5 min

Tsukishima Nishinaka-dori, a shopping street of roughly eighty monjayaki restaurants under pavement canopies, is the home of a dish that began as a flour-and-water snack cooked for children on the hotplates of penny-candy shops. Tsukishima itself is a nineteenth-century island, reclaimed from Tokyo Bay and completed in 1892.

Kawashimaya, Nishinaka-dori
7

Kawashimaya, Nishinaka-dori

5 min

Kawashimaya, a grocery and sake shop at Tsukishima 3-7-10, has traded on Nishinaka-dori since the Meiji era by its own account and still supplies both residents and local kitchens. It stands among the restaurants rather than behind them: the everyday shops of this shotengai, including a Meiji-era footwear shop and a Meiji-era bookshop, are interspersed along the same corridor.

Kachidoki-bashi
8

Kachidoki-bashi

5 min

Kachidoki-bashi, completed on 14 June 1940, is a double-leaf bascule bridge built as the ceremonial approach to a Tokyo world exposition that was cancelled as Japan went to war. Its four-thousand-tonne leaves rose to seventy degrees in about seventy seconds until the final lift on 29 November 1970; it was designated an Important Cultural Property in 2007.

A Taste of the Tour

This is the real story from one stop on this walk — every stop has one.

Tsukuda Kobashi

Start on the bridge itself. From Tsukishima station, on the Yurakucho and Oedo lines, it is a few minutes north through the alleys, and from here the whole walk runs about seventy-five minutes: eight stops, roughly two and a half kilometres, flat ground, no entry fees, and lanes narrow enough that cars mostly give up. One thing to hold onto for the next hour: almost everything you are about to look at is somebody's home. Walk the alleys quietly, and do not photograph anyone's doorway. Stand in the middle of the span and look down the water. What you are looking at is Tsukudabori, the boat basin. It is really the dead-end stub of a channel called the Tsukudagawa Shikawa, left behind when the rest of the waterway was filled in. Small boats are tied along both stone walls, hulls sitting low. Behind them are tiled roofs and two-storey houses at a height nobody builds at any more in central Tokyo, laundry out, air conditioners bolted to the walls. And rising straight up behind those roofs are the towers of Okawabata River City 21. Old kitchen, new skyline, in one frame. You do not need me to explain that view; you can simply look at it. The bridge under your feet is younger than it pretends to be. This version was completed in 1984, and the red-lacquered railings, the onion-shaped giboshi finials on the posts and the stone arching along the sides are all deliberate period dress. But a crossing has run on roughly this line since the island was finished in the 1640s. A 1679 survey map of Edo already shows the moat splitting Tsukuda into an eastern and a western half, with a bridge about where you are standing. Now look over the rail at the mud, and find the sign the Tsukuda Sumiyoshi-ko put up. Something is buried down there, and it comes out of the riverbed once every three years. The shrine two minutes from here will tell you what it is and why the mud is the right place to keep it — it is a very Tsukuda answer to a problem, and it deserves to be heard standing in front of the people who still do it. That is the thread of the whole walk. Nothing about this ground is natural. The island beneath you was made, out of tidal flats, by people who had themselves been moved here from somewhere else, and having been handed a low, awkward patch at the mouth of the Sumida on the far side of the city, they turned what they had into what Edo needed. Watch that habit repeat for the next hour. Being on the far side mattered longer than you would guess. Until 1964 there was no road bridge here at all; you reached Tsukuda by boat, and we will get to how that ended. A few stops from now, out on the embankment, this same contrast gets sharper still, and we finish the walk on a bridge a great deal bigger than this one. And if there are people with short rods along the wall, leave them to it — they are after goby, which tells you the water here is still alive.
