Gokoku-ji Gekkoden: A Momoyama Hall That Traveled from Lake Biwa
The hall that Gokoku-ji calls the Gekkoden, the Moonlight Hall, was not built in Tokyo. It went up around the year 1600 on the grounds of Onjo-ji, the great monastery on the western shore of Lake Biwa, where it served as the guest hall of a sub-temple named Nikko-in. Today it sits behind Gokoku-ji's main hall in the Otsuka district of Bunkyo Ward, roughly 400 kilometers from the spot where its timbers were first raised.
It is a single-story building of seven bays by six. (A bay, or ken, is the space between two posts, so the figure describes proportion rather than exact metres.) The roof is irimoya, a form that combines a hipped lower slope with a gabled upper one, and the entrance is set under the gable end rather than along the eaves, an arrangement called tsumairi. A small cusped gable, the karahafu, curves above the front eaves, and a separate gate of one bay square completes the group. The whole is counted in the official record as a single structure.
What it represents is a shoin hall: a formal reception building of the type that shaped upper-class Japanese residential architecture from the late sixteenth century onward.
From Lake Biwa to Tokyo
The hall reached its present site in two moves rather than one.
When the Meiji government's order separating Shinto and Buddhism in the early 1870s left countless temple buildings unwanted, the guest hall of Nikko-in was marked for disposal. The financier Hara Rokuro intervened. He had set out to buy only the painted sliding panels, the fusuma, but was talked into taking the entire building. He reassembled it inside his estate in Shinagawa and gave it a new name, Keicho-kan.
Some years afterward, Gokoku-ji needed a large hall for a tea gathering and had nothing suitable. The temple's parish representatives asked Hara to part with Keicho-kan. In 1928 the building was dismantled and raised a second time on the temple grounds, where it took the name it carries now.
Why the Hall Matters
Three reception halls of the same date and the same origin survive. The other two, Kojo-in Kyakuden (1601) and Kangaku-in Kyakuden (1600), remain at Onjo-ji, and both are National Treasures. The Gekkoden is their close relative, built in the same years and in the same transitional form that architectural historians call shudenzukuri, a stage between the older aristocratic shinden plan and the fully developed shoin style.
All three resemble the "main hall" diagrams set down in the Shomei, the carpenters' manual compiled in 1608 by Heinouchi Masanobu, master builder to the shogunate. The three halls are sometimes distinguished by who used them: the Kojo-in hall is associated with warriors, the Kangaku-in with monastic study, and the Nikko-in hall, the present Gekkoden, is said to have received visiting court nobles.
The hall was designated a National Treasure under the 1929 law on January 19, 1931. When the current Law for the Protection of Cultural Properties replaced that system in 1950, it became an Important Cultural Property, the status it holds today.
What to Look For
Because the interior is not normally open, the building is read from the outside, and there is plenty to read. The gable-end entry under its curved karahafu gives the front a quietly ceremonial face, very different from the long horizontal eaves of an ordinary temple hall.
The roof rewards attention. For most of its years in Tokyo it was covered in tile. A restoration completed in 2013, after five years of work, returned it to hiwadabuki, the layered cypress-bark covering it had worn at Onjo-ji. Roofers from Shiga, one of the few places where the craft is still practised, carried out the work, so the roof you see is closer to the building's original appearance than it had been for almost a century.
From the temple grounds you can take in the sweep of that bark roof and the overall massing of the hall even without going in. Special interior viewings are arranged from time to time, usually with a guide, and are worth checking for before a visit.
Around Gokoku-ji
The temple that hosts the Gekkoden is worth time in its own right. Gokoku-ji was founded in 1681 by Tokugawa Tsunayoshi, the fifth shogun, at the wish of his mother Keishoin, and it is the head temple of the Buzan branch of Shingon Buddhism. Its main hall of 1697, also an Important Cultural Property, is among the largest wooden buildings in Tokyo and enshrines a Nyoirin Kannon.
Near the Gekkoden rises a tahoto, a two-tiered pagoda modeled on the National Treasure pagoda at Ishiyama-dera; unlike the hall, it can be approached freely. The temple's cemetery holds the graves of several figures from modern Japanese history, among them Okuma Shigenobu, founder of Waseda University, the statesmen Yamagata Aritomo and Sanjo Sanetomi, and the financier Yasuda Zenjiro.
Getting there is simple: Gokokuji Station on the Tokyo Metro Yurakucho Line opens almost at the temple gate. The grounds are free to enter.

Q&A
- Can I go inside the Gekkoden?
- The interior is normally closed to the public. You can see the hall's exterior and its cypress-bark roof from the temple grounds, and special guided viewings are held occasionally, so it is worth checking the temple's announcements before you go.
- Why is a hall built at Lake Biwa now in Tokyo?
- It was originally the guest hall of Nikko-in at Onjo-ji in Shiga. After it fell out of use in the Meiji period, the businessman Hara Rokuro moved it to his Tokyo estate, and in 1928 it was relocated again to Gokoku-ji.
- How does it relate to the National Treasure halls at Onjo-ji?
- It is a sibling of the Kojo-in and Kangaku-in guest halls, both National Treasures, built around the same year and in the same shudenzukuri form. The Gekkoden is thought to have served visiting court nobles.
- Is there an admission fee, and how do I get there?
- Entry to the grounds is free. The temple is reached in about a minute from Gokokuji Station on the Tokyo Metro Yurakucho Line.
- What else is worth seeing at the temple?
- The 1697 main hall, an Important Cultural Property and one of Tokyo's largest wooden buildings, the tahoto pagoda, and a cemetery with the graves of figures such as Okuma Shigenobu and Yamagata Aritomo.
