Komyo-ji's Niomon
— a National Treasure gate above Ayabe
A 13th-century two-storey temple gate, designated a National Treasure, standing high on Mt. Kimio above Ayabe in northern Kyoto Prefecture.
The Niomon is the mountain gate of Komyo-ji, a Shingon Buddhist temple on Mt. Kimio (582 m) in Ayabe. It was built in the mid-13th century in a rare two-storey form: a three-bay gate with a single central entrance, under an irimoya roof finished in tochi-buki shingles — hand-split wooden shingles seldom found elsewhere in Japan. Designated a National Treasure in 1954, it is the only National Treasure structure in the northern part of Kyoto Prefecture. A restoration completed in 2018, roughly three years in the making, returned the gate close to its original appearance around its 750th year.
Why it stays quiet
The gate sits up a remote valley with a long final walk and almost no English information, and it is far off the main Kyoto tourist routes, so foreign day-trippers rarely reach it.
Background & history
Komyo-ji's founding is traditionally attributed to Prince Shotoku, and the temple belongs to the Daigo branch of Shingon Buddhism. During restoration, an ink inscription found on an upper pillar dated the gate to 1248, while a ridge-beam record places the wider construction between 1242 and 1253. Surviving two-storey temple gates from the medieval period are extremely uncommon, which is central to why this one holds National Treasure status.
What to look for — in walking order
- Mt. Kimio cedar forest
- old cedar forest surrounding the approach to the gate on the 582 m mountain
- Two-storey Niomon gate
- three bays wide with one central entrance, in the rare two-storey form, under an irimoya (hipped-and-gabled) roof
- Tochi-buki shingle roof
- hand-split wooden shingles, a covering rarely found elsewhere in Japan
- Nio guardian statues
- a pair of Kongo Rikishi (Important Cultural Properties), placed unusually in the rear bay rather than the front
How to enjoy it
By car, a mountain road climbs about 2 km from Ayabe Onsen to a parking area, then the gate is a short walk. Spring through autumn is the recommended window, as heavy snow often closes the road in winter.
How to actually get there
- Kyoto Station → Ayabe Station (JR San'in Main Line limited express, ~70 min).
- Ayabe Station → Omachi Bus Terminal (Ayabus Kanbayashi line).
- Omachi Bus Terminal → Ayabe Onsen-mae bus stop (Ayabus Omi-Ichinose line).
- Ayabe Onsen-mae → Komyo-ji Niomon gate (on foot, ~40 min uphill).
- JR train + Ayabus (with a bus transfer)
- Kyoto Station →(JR San'in Main Line limited express, ~70 min)→ Ayabe Station. From Ayabe Station take the Ayabus Kanbayashi line to Omachi Bus Terminal, then transfer to the Omi-Ichinose line and get off at Ayabe Onsen-mae bus stop. From that stop it is a walk of about 40 minutes uphill on a mountain road to the gate. Total from Kyoto is roughly 2.5 to 3 hours. These valley buses run only a few times a day, so check the day's timetable before you set out; the tourist information center at Ayabe Station's south exit can help you plan the bus.
- Return the same way to Ayabe, then by train to Kyoto
- Walk back down to Ayabe Onsen-mae and take the Ayabus back toward Ayabe Station, then the JR limited express to Kyoto. The valley buses are few and end by early evening, so when you arrive at the stop, first check the return departure times posted there and plan your visit around them. Do not rely on finding a taxi in the valley.
Before you go
- Cash
- Rural buses like the Ayabus are usually cash-only, so carry coins and small bills; there are no shops or vending machines near the gate.
- Closing days
- This is a working mountain temple with an open outdoor gate, not a ticketed site; there are no set opening hours for viewing the gate itself.
- Another way
- By car, drive via National Route 27 (turn north at the Yamaga intersection), continue up the mountain road past Ayabe Onsen to the parking area, and walk a few minutes to the gate. The road is often closed by snow in winter.
- After you get off
- From Ayabe Onsen-mae bus stop, walk about 40 minutes uphill on the paved mountain road to reach the gate.
