Tea Rooms — The Three National-Treasure Tea Rooms (Taian, Jo-an, Mittan) and the Sukiya Lineage

The Tea Room — A Total-Art Space

The tea room (chashitsu) is a dedicated building for the tea event. It developed uniquely within Japanese architecture, moving from shoin-zukuri to sukiya-zukuri, from four-and-a-half mats to two mats, and from the broad karamono-display room to the wabi grass-hut.

The tea room is not merely a place to eat and drink, but is designed as a place of spiritual exchange between host and guest, a total space in which architecture, garden, utensils, and gesture are unified. Within Japanese architectural history, the style called “sukiya” has had a deep influence on modern residential and Japanese-style architecture.

The Dōjinsai — The Prototype of the Tea Room (1486)

Ashikaga Yoshimasa’s “Tōgudō Dōjinsai” within the Higashiyama-dono (Ginkaku-ji) (established 1486) is a four-and-a-half-mat shoin-zukuri room and the prototype of the tea room.

Features of the Dōjinsai

• Nearly square four-and-a-half-mat space
• Tsuke-shoin (a bay-like desk) and chigaidana (staggered shelves)
• Oshi-ita — the prototype of the tokonoma
• Sliding doors of shōji and fusuma

This became the starting point from which Jukō’s grass-hut four-and-a-half mats and Rikyū’s Taian would be shrunk and made wabi. From here the “genes” of the tea room branch for 500 years.

Compression History of the Tea Room

The tea room was shrunk in stages from a four-and-a-half-mat room:

• Jukō’s four-and-a-half-mat grass-hut — Mud walls, straw-chaff rough walls (from shoin’s paper-covered walls)
• Jōō’s four-and-a-half-mat — Shitaji-mado, menkawa-bashira, thatched ceiling
• Rikyū’s three-mat plus daime, two-mat plus daime — Further shrinkage, invention of the nijiri-guchi
• Rikyū’s two-mat (Taian) — The extreme
• Rikyū’s one-and-a-half-mat — The ultimate (only as prototype)
• One mat — Only as a hypothetical, not viable in practice

The practical limit is one-and-a-half to two mats, and the Taian is recognized as essentially the final form. A counterintuitive architectural philosophy: smallness itself produces density.

The Nijiri-Guchi — A Device to Erase Rank

The nijiri-guchi is Rikyū’s invention: a small entrance about 66 cm square. Guests enter bent over and lowering the head:

• Even a samurai removes his sword to enter (one cannot enter with a sword at one’s side)
• High and low enter in the same posture
• The distinctions of rank are physically erased

Rikyū’s thought that “the tea room is a space of equality” is embodied in the architectural design — a jewel of an invention. A single physical constraint — “a small entrance” — philosophically transforms the meaning of the space.

The Three National-Treasure Tea Rooms — Taian, Jo-an, Mittan

Only three tea rooms have been designated National Treasures:

1. Taian — Sen no Rikyū, Myōki-an in Yamazaki, Kyoto, two mats
2. Jo-an — Oda Uraku, Uraku-en in Inuyama, Aichi, two and a half mats plus daime
3. Mittan — Kobori Enshū, Ryōkō-in of Daitoku-ji, Kyoto, four and a half mats plus daime

Taian — Rikyū’s Only Extant Tea Room

Taian is the only extant tea room said to have been built by Sen no Rikyū. It lies inside Myōki-an in Ōyamazaki, Otokuni District, Kyoto. It is the head of the three tea rooms designated National Treasures in 1951.

The Taian

• Location — 56 Ōyamazaki Ryūkō, Ōyamazaki-chō, Otokuni District, Kyoto (within Myōki-an)
• Built — In Tenshō 10 (1582), estimated to be right after the Battle of Yamazaki
• Design — Sen no Rikyū
• Scale — Two mats (one guest mat + one point-serving mat)
• Layout — The two-mat tea room + a one-mat antechamber + preparation
• Designation — National Treasure (1951)

Architectural Features of the Taian

• Area — Two mats (about 3.3 square meters)
• Tokonoma — Muro-doko, integrated with the wall, mud with rounded corners
• Entrance — Nijiri-guchi, about 66 cm square
• Walls — Mud walls, rough walls with straw chaff
• Ceiling — Combined bamboo/reed keshō-yaneura (exposed roof structure) and flat ceiling
• Windows — Two shitaji-mado, one renji-mado
• Pillars — Cedar square (partly log)
• Toko-gamachi — Paulownia lintel (no ordinary lintel; natural step)

The Muro-Doko — The Height of Rikyū’s Creation

The tokonoma of the Taian is a distinctive form called the “muro-doko”:

• The ceiling of the tokonoma is lowered and joined to the wall by curved forms
• All corners rounded in the mud so as to give an impression like the inside of a cave
• Simplification of the toko-gamachi
• Decoration reduced to the minimum

This ambiguous, softened tokonoma brings deep depth into the small two-mat space. The height of Rikyū’s inventiveness. Erasing the boundary between wall and tokonoma, the space appears to continue endlessly.

The Battle of Yamazaki and the Taian

In the sixth month of Tenshō 10 (1582), after Akechi Mitsuhide’s Honnō-ji Incident, Hashiba Hideyoshi (Toyotomi Hideyoshi) hurried from Bicchū Takamatsu and defeated Mitsuhide at Yamazaki. This is the Battle of Yamazaki.

Just after this, Hideyoshi built Yamazaki Castle and ordered Rikyū to make a tea room. This is said to be the Taian. Yamazaki Castle was abolished shortly after, and only the Taian was moved to Myōki-an and has survived to the present — so the tradition holds.

Details remain debated: “was the Taian truly by Rikyū?” and “was it inside Yamazaki Castle, or was it always at Myōki-an?” But it is certain that the Taian is the most important tea room, embodying Rikyū’s wabi-cha.

Experiencing the Taian

The Taian is opened to the public a few times a year at Myōki-an, by advance application. A visit takes about 15 minutes.

Guests pass through the roji and reach the nijiri-guchi. Bowing to enter a doorway about 66 cm square, one meets a two-mat space, dark and narrow. The weight of the mud walls, the low ceiling, the muro-doko — for a modern person there is a sense of oppression.

But as one lowers to sitting and watches the host prepare the tea, the meaning of the space begins to change. Host and guest are about a meter apart; the physical closeness draws the spirits close as well.

Rikyū’s intention: it is the extreme small space of two mats that makes possible the deepest encounter between people.

Jo-an — Oda Uraku’s Tea Room

The second of the three National-Treasure tea rooms, “Jo-an,” was built by Oda Uraku (Nobunaga’s younger brother, Nagamasu, 1547-1622).

• Location — Uraku-en, Inuyama, Aichi; moved from Meiji Jingū Gaien
• Built — Around Genna 4 (1618), at Shōden-in of Kennin-ji, Kyoto
• Scale — Two and a half mats plus daime (two-and-a-half guest mats + daime mat point-serving seat)
• Features — The “Uraku window” (a lattice window), calendar-papered walls, triangular ji-ita

Jo-an has been repeatedly moved. Shōden-in of Kennin-ji, Kyoto → Mitsui residence in Tokyo → Mitsui residence at Ōiso → Uraku-en, Inuyama (moved 1972). It is visible today at Uraku-en in Inuyama.

Mittan — Kobori Enshū’s Height

The third of the three National-Treasure tea rooms, “Mittan,” was built by Kobori Enshū.

• Location — Ryōkō-in of Daitoku-ji, Murasakino Daitokuji-chō, Kita-ku, Kyoto
• Built — In the Kan’ei era (1624-1644)
• Scale — Four and a half mats plus daime
• Features — Named for the “Mittan Kanketsu” bokuseki of Engo hung in the tokonoma

Mittan is at the back of the hōjō of Ryōkō-in of Daitoku-ji and is closed to the public. It cannot be seen by ordinary visitors. It is considered the acme of the Rikyū → Oribe → Enshū line as the summit of shoin-sukiya.

“A National Treasure that cannot be seen” — a symbol of the beauty of secrecy in Japanese culture. A rare case in which the highest evaluation is given to a building that cannot be seen.

Elements of the Tea Room

Typical elements:

• Tokonoma — Where a scroll and flowers are displayed; the first thing a guest views
• Temae-za — Where the host prepares tea; often a daime mat
• Kyaku-datami — Where the guests sit
• Nijiri-guchi — The guest entrance, about 66 cm square
• Kinin-guchi — A larger entrance for a high-ranking guest
• Sadō-guchi — The host’s entrance
• Kyūji-guchi — An entrance for serving
• Shitaji-mado — A window left with the plaster removed
• Renji-mado — A latticed window
• Tsukiage-mado — A ceiling window
• Naka-bashira — A pillar separating the temae-za and kyaku-datami
• Taiko-busuma — A fusuma adjoining the naka-bashira

“Shin, Gyō, Sō” — Three Formal Grades

Tea rooms fall into three formal grades — “shin, gyō, sō”:

• Shin — Most formal, shoin-zukuri, four and a half mats or larger, shoin-doko
• Gyō — Intermediate, a mix of shoin and grass-hut, four and a half mats plus daime, etc.
• Sō — Most wabi, grass-hut, three or two mats, mud floor

This is a grading concept shared with calligraphy, flower arrangement, and temae, and serves as a criterion for choosing a tea room in accordance with the guest’s rank. The thought of “even in the same tea event, choose the space to suit the guest” — a host-guest oneness.

Edo-Era Sukiya — Shoin-Sukiya

In the early Edo, Kobori Enshū’s “kirei-sabi” spread, and the tea room turned again toward fusion with the shoin. A middle-way style between the broad room and the wabi tea room called “shoin-sukiya” was established:

• The tea rooms of Katsura Rikyū — Shōkin-tei, Shōka-tei, Shōi-ken, Geppa-rō
• The Bōsen seat of Kōhō-an of Daitoku-ji — Enshū’s own
• The Hasso-seki of Konchi-in — sub-temple of Nanzen-ji, Kyoto

Katsura Rikyū is a masterpiece of sukiya, valued internationally. In the mid-Edo and after, each school made iemoto-taste tea rooms, and diverse formats — four and a half mats, three mats plus daime, two mats plus daime — took hold.

Bruno Taut and the International Discovery of the Taian

Bruno Taut (1880-1938) was a German architect. When he stayed in Japan from 1933 to 1936 to escape from the Nazis, he praised Katsura Rikyū and the Taian to the world ([The Rediscovery of Japanese Beauty], 1939):

• “So beautiful I could weep” (on Katsura Rikyū)
• He placed the Taian and Katsura Rikyū among the summits of world architecture

Through this, the tea room, until then regarded as “a peculiar architecture only Japanese could understand,” was reevaluated as a treasure of world architecture. One source of the world “minimalism” and “minimal space.”

Modern Architects and the Taian

Modern Japanese architects have also studied the Taian deeply:

• Taniguchi Yoshirō, Horiguchi Sutemi — deepened tea-room studies from the Taian
• Isozaki Arata, Andō Tadao — modern architects who also learn from the Taian

The Taian is positioned as the root of the global spread of “Japanese minimalist architecture.” A two-mat space of 400 years ago still influences contemporary international architecture.
