A Gate That Outlived Everything Behind It
The Former Taitoku-in Mausoleum Main Gate (旧台徳院霊廟惣門, Kyu Taitoku-in Reibyo Somon, also written Kyū Taitokuin Reibyō Sōmon) stands in Shibakoen, Minato City, Tokyo. It was built in 1632 and designated on 23 May 1930, and today holds the rank of Important Cultural Property. Taitoku-in was the posthumous Buddhist name of Tokugawa Hidetada (1579 to 1632), second shogun of the Edo period. His mausoleum was raised on the southern side of Zojoji temple by his son Iemitsu, the third shogun, in the year Hidetada died.
The structure is a hakkyaku-mon, an "eight-legged gate" in which four subsidiary columns front and back brace the two main posts. It runs three bays across with a single opening at the centre. Above sits an irimoya roof, hipped below and gabled above, laid in copper tiles that long ago turned a dull sea green. At the skirt of the eaves, on the outer face and again on the inner one, a karahafu rises in the undulating bargeboard profile Japanese carpenters reserved for entrances of consequence.
Approach from Hibiya-dori and the proportions register before any of the detail does. This was the outermost gate of the complex, the one a visitor met first, and its scale was calculated to announce what stood beyond it.
What stood beyond it is gone.
Designation, Fire, and the Four Gates
Fifteen structures of the Taitoku-in mausoleum were placed under national protection in 1930. Architectural historians rank the complex among the most ornate of the Tokugawa mausolea, and it is frequently described as the design from which Nikko Toshogu took its cues. The main hall, the connecting chamber and the worship hall formed a single gongen-zukuri building enclosed by openwork fences, with a five-storey pagoda standing nearby.
On the night of 25 May 1945 the bombing of Tokyo reached Shiba. Nearly all of it burned. Five elements survived: this Main Gate, the Chokugaku-mon, the Choji-mon, the Onari-mon, and the stone railing of the inner precinct. When the Cultural Properties Protection Law took effect in 1950, the survivors were reclassified as Important Cultural Properties, the rank they carry now. In 1960 three of the four gates were dismantled and re-erected at Sayama Fudoson in Tokorozawa, Saitama, where they can still be seen. The Main Gate alone remained in Shiba.
It did not remain entirely still. Local records hold that in 1959, when the surrounding land was redeveloped, the gate was shifted roughly forty-five metres east of its original footing. The distance is small enough that the gate still reads as belonging to this ground, and large enough that the processional axis it once terminated no longer exists.
Anyone curious about what the gate introduced should walk five minutes north to Zojoji. The Treasure Gallery in the basement of the main hall displays a one-tenth scale model of the mausoleum, built for the 1910 Japan-British Exhibition in London under the supervision of the sculptor Takamura Koun and the architectural scholar Kouda Minoru. Presented to the British royal family when the exhibition closed, it entered the Royal Collection, came back to Japan in April 2014 on long-term loan, and has been on permanent display since April 2015. The model measures roughly four by six metres. Photographs of the vanished buildings survive only in black and white, so the model is the one place the colour can be judged.
What to Look For on Site
Two Nio guardian figures occupy the gate, one on either side of the passage, standing on rock-form pedestals set over square bases. Minato City has designated the pair a Tangible Cultural Property. They are yosegi-zukuri, assembled from joined blocks of wood and coloured over a tonoko ground. Repairs in 2004 and 2005 turned up an inscription inside one of the bodies. It recorded that the figures had originally stood in the Nio gate of Saifukuji, a Shingon temple in present-day Nishitateno, Kawaguchi City, Saitama; that they were repaired in 1789 and again in 1847; that a storm in 1855 left them damaged in a corner of the temple's Kannon hall; and that a third repair in 1948 was followed by a transfer to Sensoji in Asakusa. Their later arrival at this gate is not documented in comparable detail.
The gate sits in open public space along Hibiya-dori, at the east approach to The Prince Park Tower Tokyo, with the right-hand side road carrying cars and the left-hand side kept for people on foot. There is no gatekeeper, no ticket, no closing hour, and no restriction on photographing it from the street. Tokyo Tower rises directly behind, which produces the picture most visitors leave with: 1632 in the foreground, 1958 above it.
Two details repay a slower look. The copper tiles are pressed into the profile of ceramic roof tiles, a deliberate imitation in a more durable metal, and the seams between them catch light quite differently in rain than in dry weather. The other is the karahafu: the national register specifies one on the front and one on the back, so turn around after passing through rather than reading the gate from one side only.
Shibakoen Station on the Toei Mita Line is about five minutes away on foot, Onarimon Station about seven, and Akabanebashi Station on the Toei Oedo Line roughly the same. Zojoji, the Tokugawa family cemetery behind it, and Tokyo Tower all fall within a fifteen-minute walk of one another, which makes the gate an efficient first stop rather than a destination in itself.

Q&A
- Can anyone visit the Former Taitoku-in Mausoleum Main Gate? Is there an admission fee or opening time?
- Yes. The gate stands on a public thoroughfare beside Hibiya-dori and can be seen at any hour without charge. It is not an enclosed site, so there are no opening hours and no ticket. The land around it belongs to the hotel grounds of The Prince Park Tower Tokyo, so ordinary courtesy applies, but passing through the gate is normal and expected.
- Where is the Former Taitoku-in Mausoleum Main Gate and how do I get there?
- The address is 4-8-2 Shibakoen, Minato City, Tokyo. Shibakoen Station on the Toei Mita Line is about a five-minute walk, Onarimon Station about seven minutes, and Akabanebashi Station on the Toei Oedo Line about seven minutes. Zojoji temple lies roughly five minutes north on foot.
- Can I photograph the Former Taitoku-in Mausoleum Main Gate?
- Photography from the street and the pedestrian path is unrestricted, and the gate with Tokyo Tower behind it is the standard shot. Tripods and any filming that would obstruct hotel traffic are a different matter and should be cleared with the hotel first.
- What are the two statues standing inside the Former Taitoku-in Mausoleum Main Gate?
- They are a pair of Nio, the muscular guardian figures placed at temple gates to repel harm. Minato City has designated them a Tangible Cultural Property. A repair inscription discovered in 2004 to 2005 shows they came from Saifukuji temple in Kawaguchi, Saitama, by way of Sensoji in Asakusa, so they were not made for this gate.
- What happened to the rest of the Taitoku-in mausoleum, and where are the other gates now?
- Most of the complex burned in the air raid of 25 May 1945. Of the four gates that survived, three were moved in 1960 to Sayama Fudoson in Tokorozawa, Saitama, and only the Main Gate stayed in Shiba. To see the whole layout as it once was, visit the Treasure Gallery beneath the main hall of Zojoji, where a one-tenth scale model built in 1910 is on permanent display.
