The Sutra Hall of Kawaraya-ji and Its Turning Library
South of the main hall at Kawaraya-ji, facing north, stands a compact square building that houses one of the temple's most engaging pieces of carpentry. This is the Kyōdō (経堂), the sutra hall, also called the Kaiinzō (海印蔵). Built in 1725 (Kyōhō 10), it is three bays square (hō-san-ken, 方三間) under a pyramidal tiled roof, and it was made to hold and turn a collection of Buddhist scriptures.
Kawaraya-ji sits on the slopes of Mitsukuri-yama in Higashiōmi, Shiga, a Rinzai Zen temple of the Myōshin-ji branch. Local tradition ties its origin to Prince Shōtoku, who is said to have fired well over one hundred thousand roof tiles on this mountain for Shitennō-ji in Ōsaka, leaving the temple its tile-kiln name. The complex burned in 1568 during Oda Nobunaga's campaign in the region and was revived from the mid-1640s by the Zen monk Kōzan Sokei. This sutra hall belongs to the wave of building that followed that revival.
A Design Held Up as a Model
The Kyōdō was registered as a National Registered Tangible Cultural Property on 27 March 2018, registration number 25-413. Among the seven Kawaraya-ji buildings listed that day, it is the only one entered under the criterion of works that serve as a model of design, rather than the more common landscape criterion, a distinction that points to the quality of its construction.
At its centre stands an octagonal rinzō (八角輪蔵), a revolving sutra case that pivots on a central axis so that a full turn is counted as the merit of reading every scripture it holds. The framing around it is what draws the eye upward: fire-brace beams (hiuchi-bari, 火打梁) span the four corners, tall struts (taiheizuka, 太瓶束) rise from them, purlins run around all four sides, and curved ebi-kōryō (海老虹梁), "shrimp beams," tie the inner structure back to the outer columns. The square columns carry hira-mitsudo (平三斗) bracket sets; sankarado (桟唐戸) board doors fill the central bay of each face, while cusped katōmado windows open only in the two front end bays.
What to Look For on a Visit
Where the founder's hall nearby reads as a study in restraint, the sutra hall is about the drama of a roof seen from below. If you can view the interior, look up first: the shrimp beams and struts turn a small room into a piece of three-dimensional joinery worth lingering over. The revolving case itself is a rare survival, and the idea behind it, that turning the library equals reading it, is one of the more approachable expressions of Buddhist practice for a first-time visitor.
The hall stands within easy reach of the main hall and the other registered buildings, so it is best seen as one stop on a slow walk through the grounds. Come in mid-November and the maples frame the whole compound in red; come in early summer and the same slopes run bright green. Seated meditation and sutra copying are available by reservation for those who want to slow down further.
Q&A
- What is a rinzō, and why does it turn?
- A rinzō is a revolving case for storing sutras. By tradition, rotating it once is credited with the same merit as reading the entire scripture collection it contains.
- Why is this building considered special among the seven?
- It is the only one of Kawaraya-ji's registered buildings listed under the criterion of serving as a model of design, reflecting the quality of its interior framing and its revolving library.
- What is the "Kaiinzō" name about?
- Kaiinzō is an alternate name for the sutra hall. The term evokes the Buddhist image of a mind that reflects all things clearly, like a calm sea.
- When was it built?
- In 1725 (Kyōhō 10), during the building activity that followed the temple's seventeenth-century Zen revival.
- Can I see the revolving case in motion?
- Interior access and operation depend on the day and on temple arrangements, so ask at the temple office before your visit.
