If you're interested in visiting the shrine, here is a map:
Nearby is another famous temple- Shoden-ji. Shoden-ji is located about twenty minutes east of Ota Shrine by bicycle. Shoden-ji has a peculiar history. It's original attraction was its Karesansui garden, which is considered a masterpiece, but these days, at least from foreigners' perspective, its Chitenjo, or bloody ceiling is the true reason to go. The Town Mouse and I heard of the temple from local magazine Kansai Scene in their "Haunted Places" editorial. Going there, I was expecting to find the temple in poor repair, or at the very least, to feel a bit of a spookiness or dread. I actually felt neither.
The ceiling of the temple is made from some recovered floorboards of Fushimi Palace, where a troop of soldiers committed harakiri suicide in 1600. The floorboards were re-purposed into the veranda's ceiling as a way to offer the restless souls repose. The temple is actually quite stunning and serene. While not overtly grand or unique, the sense of quiet you can get up on the mountain while staring out over the garden is fantastic. While we were there, they also had a large "Death of Buddha" scroll on display. At first glance, the scroll simply looked unfinished, but upon closer inspection, I realized that it was quite finished: the entirety of the scroll had been drawn in kanji.... lines and lines of sutras. It was gorgeous. I would have to say that if you're in the area, it's definitely worth a visit. Here is a map to Shoden-ji:
