Why go past Yamadera?
Yamadera (山寺), the mountain temple of Risshaku-ji, is one of Yamagata’s best-known sights. Behind it lies an area people call Ura-Yamadera, “the back of Yamadera”. Its formal name is Mine-no-ura (峯の浦), and according to Yamagata’s official tourism site it is said to be where the monk Jikaku Daishi Ennin worked out his plans for founding Yamadera.
Mine-no-ura has several stops, including Senju-in temple, a rock known as Eboshi-iwa and former training grounds for mountain ascetics. The official guide singles out Tarumizu Ruins (垂水遺跡) as the highlight of the area.
What you will find at Tarumizu
The ruins sit about 15 minutes’ walk from the start of the mountain path. Walk through the forest and you reach a large rock face pitted with small holes like a honeycomb, with a torii gate in front of it.
According to the same source, mountain ascetics (yamabushi) trained here until the Taisho era (1912–1926). A figure of Fudō Myōō, a guardian deity in esoteric Buddhism, is enshrined in a crack in the rock, and remains of ascetic practice and caves with gorintō stone stupas survive nearby.
Getting there
The official directions are short: about five minutes by car from JR Senzan Line Yamadera Station to the entrance of the approach path, then about 15 minutes on foot to the ruins. Plan how you will reach the trail entrance before you set off, and allow time to walk back.
When to go
Entry is prohibited in winter, usually from around December until the end of March. Outside that period, check the current notice for visitors from the Yamadera Tourism Association, which the official listing links under its websites, and follow any signs on site. We do not report live trail conditions, weather or autumn colors.
Pair it with
Yamadera itself (Hōjusan Risshaku-ji) and the Yamadera Bashō Memorial Museum are listed by the same official site as nearby spots, which makes Tarumizu a natural add-on to a Yamadera day rather than a separate trip.

Before you go
- The walking time is measured from the trail entrance, not from Yamadera Station. We have not verified a walking route or taxi availability from the station.
- The Yamadera Tourist Information Center is open 9:30–16:00 from April to November and 10:00–15:30 from December to March, closed on Wednesdays. These are the office's hours, not opening hours for the ruins.
- The official listing links a guided hiking tour of the ruins run by DMC Tendo Onsen, an option if you would rather not plan the walk yourself.
