Former Kajii Palace Gate

A 1703 Imperial Gate Standing Across from Nijō Castle

Walk down Aburanokōji Street, just south of Nijō Avenue, and the modern hum of central Kyoto suddenly meets something else: a broad-roofed wooden gate of weathered timber and dark tile, its eaves curving outward in a low, deliberate sweep. This is the Kyū Kajii-no-miya Gomon, the former gate of the Kajii-no-miya imperial monzeki residence. It was raised in 1703, the sixteenth year of the Genroku era, and it has watched over three different Kyoto addresses across its long working life.

Today the gate serves as the main entrance of Hotel The Mitsui Kyoto, which faces the World Heritage Site of Nijō Castle just across the road. Anyone may pass beneath it. Hotel guests step through; visitors stopping by for the restaurant or the tea lounge step through; passers-by drawn in by the silhouette walk up to it. In a city where so many gates belong to walled temple precincts and ticketed gardens, this one stays open to the street.

From Monzeki Court to Merchant Residence

To understand the gate, it helps to know what stood behind it three centuries ago. Kajii-no-miya, also written Kajii Monzeki, was one of the highest-ranking Tendai Buddhist temples in Japan, an institution whose abbots were drawn from the imperial family. It is the same lineage that today is known as Sanzen-in, the celebrated mountain temple in Ohara, north of Kyoto. Before the Meiji Restoration, however, its main hall sat not in Ohara but at the edge of the Kyoto Imperial Palace grounds.

In 1698, the fifth Tokugawa shogun, Tsunayoshi, granted Kajii-no-miya a parcel of land near the imperial palace, in what is now Kajii-chō in Kamigyō Ward. The temple complex relocated there, and the gate now standing on Aburanokōji was built five years later, in 1703, as the formal entrance to the monzeki residence on that imperial-palace site. For roughly a century and a half it received princely abbots, court nobles, and the carriages and palanquins that came with them.

The Meiji Restoration ended that life. Anti-Buddhist policies dismantled many monzeki institutions, and Kajii-no-miya's Kyoto headquarters were broken up. The temple's relics and name eventually migrated to Ohara, where in 1871 the consolidated establishment was renamed Sanzen-in. The gate itself, separated from the temple it once announced, would wait several more decades for a new home.

That home came in 1935, when the gate was carefully dismantled and moved south to Aburanokōji, where it became the entrance to the residence of the Mitsui Sōryōke, the head household (known as the Northern House) of the Mitsui merchant dynasty. The Mitsui had held this block since 1691, when Mitsui Takahira, eldest son of the founder of the Echigoya draper's shop, established his Kyoto residence here. The gate's third life, then, was as the threshold of a merchant prince's compound.

Why the Designation Came in 2021

In October 2021 the gate was added to Japan's Registered Tangible Cultural Properties under the name Kyū Kajii-no-miya Gomon. The Agency for Cultural Affairs registers structures that are at least fifty years old and meet at least one of three tests: contributing to the historical landscape of the country, serving as a model of craftsmanship, or being difficult to reproduce. The gate met all three.

Architecturally, it is a single-bay, single-door yakui-mon, a gate type built on four pillars with a ridge set slightly forward of center, throwing the front pair into greater prominence. The roof is finished in hongawara, the heavy pan-and-cover tile traditionally reserved for temples and the homes of the highest-ranking samurai and aristocracy. The pillars are notably thick square posts; four beams sit on the crossing kabuki lintel; a rain-shedding strut called a minozuka, fitted with carved floral brackets known as hana-hijiki and a triple-stepped bracket complex called mitsudo, holds up the ridge. The eaves are doubled, with closely-spaced rafters, and the tail ends of the beams and rafters are finished in gofun, a white pigment made from ground oyster shell, applied along their carved curving profiles. It is, in the careful phrase of the Agency for Cultural Affairs, a "flamboyant design appropriate to a monzeki residence."

What also matters is what was kept. The 2020 restoration disassembled the gate and its side walls into roughly one thousand individual parts. Each piece was examined; damaged elements were repaired or replaced where unavoidable; sound timber was put back. More than half of the original roof tiles were reused. Past repairs every thirty to fifty years had kept the structure standing, but this was the most thorough work done on it since the 1935 move. The miyadaiku — temple-and-shrine carpenters trained in traditional joinery — who carried it out came from Fukui Prefecture, working under a major contractor that specializes in religious architecture.

What to Notice When You Stand Beneath It

The gate is roughly 4.5 meters wide between its main pillars and rises about 7.4 meters at the ridge. From across Aburanokōji, the proportions seem almost squat, but step closer and the upward sweep of the eaves and the depth of the bracket work become apparent. Look up at the underside of the eaves: the rafters run in two staggered tiers, and at every tail end you can see the soft, slightly chalky finish of the shell-white paint over carved contours. This was not utilitarian carpentry. It was meant to announce, in 1703, that someone of imperial standing lived behind it.

The patina is its own pleasure. Three hundred years of Kyoto weather — humid summers, snowy winters, the long slow oxidation of paint and wood — have given the timbers a soft, almost greyed warmth that fresh restorations cannot fake. The Japanese term furutsuya covers it: an old gloss, an aged sheen. Run your eye along the kabuki lintel and the way the dark grain shows through the lighter weathered surface tells you more about the gate's age than any plaque.

The side walls flanking the doors — the sodebei — were restored along with the main structure and now anchor the gate visually to the modern hotel facade behind it. They also screen the inner courtyard, so that crossing the threshold genuinely feels like a transition from street to inner garden, just as it would have for an Edo-period visitor.

Around the Gate

Nijō Castle is directly opposite. Built in 1603 as the Kyoto residence of Tokugawa Ieyasu and the site, in 1867, of the formal handover of power that ended the shogunate, the castle is the obvious pairing for a half-day visit. The Karamon front gate and the Ninomaru Goten palace, both National Treasures, are within easy walking distance of the Kajii-no-miya gate.

For the gate's spiritual descendant, the trip is longer: Sanzen-in lies in Ohara, an hour north of central Kyoto by Kyoto Bus from Demachiyanagi or Kokusaikaikan. The temple's stone-walled approach, its moss garden in the Yūsei-en, and the National Treasure Amida triad in the Ōjō-gokuraku-in hall give a sense of where the imperial monzeki tradition continues today.

Closer at hand, the streets around Aburanokōji and Oike preserve the grid of central Kyoto's old merchant quarters. A short walk east brings you to Shinmachi and Muromachi streets, lined with surviving machiya townhouses and the kind of small kissaten and craft shops worth slowing down for. The hotel's own garden, designed to flow from the gate inward, is visible from several public spaces on the ground floor.
