Minase Shrine Tea House

The Tea Room Named After Lamp Wicks

Minase Jingū Chashitsu (水無瀬神宮茶室, also known as Tōshintei 燈心亭 or Tōshinseki 燈心席), the tea house standing in the precinct of Minase Jingū at Hirose, Shimamoto Town, Mishima District, Osaka Prefecture, is an early Edo-period building dated between 1615 and 1660 and designated an Important Cultural Property on 19 April 1926.

The ledger of the Agency for Cultural Affairs gives the frame as 7.6 metres by 5.2 metres, one storey, a yosemune hipped roof under thatch, with a shingled eave along the east face. One building. Designation number 00819.

The name comes from what is overhead. The coffered ceiling is filled not with painted panels but with plant stems, each compartment packed with a different species: yamabuki (Japanese kerria), reed, bush clover, horsetail, tsukumogusa and others. The register kept by Osaka Prefecture counts ten kinds in all, one to a coffer. Every one of them was material for tōshin, the pith wicks that burned in oil lamps. Before the early Shōwa years the room went by a different name, Nanakusa no Seki, the room of seven grasses.

A tea room built out of lamp wicks is a joke with a straight face. The materials are the cheapest things in a household, and they are arranged in the most formal ceiling type Japanese architecture has.

How the building reached Shimamoto is transmitted rather than documented. The shrine and the town both record that it was moved here from the imperial palace in Kyoto. Several accounts add that Retired Emperor Go-Mizunoo (1596-1680), who is said to have felt a strong attachment to the memory of Go-Toba, granted a tea room he favoured to the Minase family; some place the construction in the Kanei era of 1624 to 1644. Sources differ, and the Agency for Cultural Affairs commits to nothing more precise than the early Edo period.

A Court Tea Room, Preserved as Designated

The plan inside is a san-jō daime: three full tatami mats plus a daime, the shortened mat that marks the host's place. Beside it lies a mizuya preparation space of the same footprint, with a three-mat service room and, to the northeast, a larger two-mat preparation room.

Two grammars run at once in this room.

Facing the guests are a tokonoma alcove and staggered shelves set side by side, which is the standard decorative arrangement for the principal room of a formal shoin drawing room. The alcove is a kekomi-doko, shallow enough to read almost as a display board. Yet the roof outside is thatch over a hipped frame, the profile of a farmhouse, and the ceiling is stuffed with weeds.

That deliberate collision is what specialists mean by sukiya-fū shoin, a shoin in the manner of the tea hut. The rustic vocabulary of the grass-hut tea room is used without surrendering the rank that a shoin carries. The Osaka register describes the ceiling as a fukiyose-gōtenjō, a coffered ceiling with the grasses drawn together in bunches, and notes that the host's place has a separate kama-tenjō with black bamboo used for the battens. Pine, bamboo and plum turn up among the timbers elsewhere in the room.

Tea rooms made for court taste in the first half of the seventeenth century are not numerous. Most tea architecture that survives from the period was built by or for tea masters and warriors; this one carries the lighter, more decorative preferences of the Kyoto aristocracy, and it survives with its interior intact.

The 1926 designation covered this building together with the guest hall across the garden, on a single day, under the pre-war protection system. Both were reclassified as Important Cultural Properties when the Law for the Protection of Cultural Properties took effect in 1950. Their ledger numbers, 00818 and 00819, still run consecutively.

Seeing the Tea House, and Drinking There

Unlike the guest hall, this building can be visited.

The shrine's own page for the tōshinseki gives the current terms: 1,000 yen per person, bookings accepted from a single visitor, advance reservation requested, and the commentary delivered as a video that visitors watch on their own phone inside the room. An older summary page on the same site still lists 500 yen for parties of five or more and excludes children of junior high school age and under, so a telephone call to 075-961-0078 before travelling will save disappointment.

Tea is still made here, which is the point of the building.

The Tōshinkai holds a tsukigama, a monthly kettle, on the second Sunday of the month, with August left open. Hosting rotates among teachers of Omotesenke, Urasenke, the Sōhen line and others, and the annual programme is published on the shrine's site. Three tea offering rites fall in the calendar: Urasenke on 5 April, Omotesenke on 14 October alongside the rite for Emperor Juntoku, and Mushakōjisenke on 13 November alongside the rite for Emperor Tsuchimikado.

The water is part of why tea settled here. Rikyū no Mizu, the spring in the precinct, is the only water in Osaka Prefecture named to the national list of one hundred famous waters, and is drawn from groundwater of the Minase River. It is available from 6:00 to 17:00, twenty litres per person per turn. Sen no Rikyū is said to have favoured it, though that attribution is traditional rather than documented.

From the tea house, the thirty-mat guest hall is visible across the garden, and the reverse view works too. Seeing both in one visit gives a fuller picture than either alone.

Access is straightforward: about ten minutes on foot from Minase Station on the Hankyu Kyoto Line or Shimamoto Station on the JR Kyoto Line, about fifteen from Yamazaki Station. Parking is free, coaches need to reserve, and pets have not been admitted since August 2021. The precinct itself has no closing hour; the office runs from 9:00 to 17:00.

Photography rules inside the tea room are not published, so confirm when booking.
