As everyone has written, it is Tenmangu Shrine located at the Demon Gate of Horyuji Temple.
During the Autumn Festival, the divine spirit mikoshi is moved to the Otabisho within the grounds of Horyuji Temple.
On the way, the five major drum stands and lanterns of Namimatsu, Nishisato, Higashiri, Gochomachi, and Sanmachi come together at Higashidaimon of Horyuji Temple, and they move in order (the order is determined each year) to Minamidaimon, where the sacred spirit mikoshi stays for two days at the shrine in the precincts.
At the Matsuyoi Shrine held in September, the lantern will be purified at Ikaruga Shrine. At Tori, children from the children's club, officers, parents, and members of the drumming committee are participating.
The guardian dogs are located between the worship hall and the main shrine, and basically you cannot approach them.
From New Year's Eve to New Year's Day, tents are set up and there are fortune tellers and rakes. Sacred sake will also be served.
It's a stamp, but it's getting thinner...😢

This is an interesting shrine. It's a small shrine nestled on the side of a mountain, and although the shrine office was closed that day, you can get the goshuin stamp yourself. However, there are stamps, and you have to stamp them yourself. Still, something made me happy. The firstfruits are at your disposal.
Ikaruga Shrine is located in Nara Prefecture and is one of the shrines deeply rooted in Japanese history and tradition. Ikaruga Shrine is said to have been built during the Asuka period and is one of the most important shrines associated with Japan's ancient history and mythology. Its sacred atmosphere and historical value impress visitors. The natural beauty of the surrounding area is also spectacular, and visitors are captivated by the changing scenery of each season. Ikaruga Shrine is a wonderful place to experience Japanese culture and history.
It was fun to get your own goshuin stamp.
It's about a 10-minute walk north of Horyuji Temple. At the information center of Horyuji Temple, the guide staff advised us, ``The area around Ikaruga Shrine is beautiful.''
Tenmangu Shrine, dedicated to Michizane Sugawara, is located on a hill overlooking a reservoir. He is the god of learning. As the guardian deity of the Demon Gate of Horyuji Temple, it was originally performed rituals at Horyuji Temple, but it seems that due to the Meiji era's ordinance separating Shinto and Buddhism, it was managed separately. The precincts were beautifully maintained, but there were no Shinto priests on duty, so the goshuin stamps were self-purchased. A stamp set was prepared on a stand next to the main shrine, complete with stamps and a brush pen for writing the date.
Although it bears the name of the town of Ikaruga, it is a small shrine and there is no resident priest.
Anyway, Ikaruga Shrine is located at the demon gate of Horyuji Temple.
However, since it is a shrine that enshrines Lord Suga, its history is not that old, and I am curious about how Horyuji's demon gate was protected before Ikaruga Shrine was built.
Also...the goshuin stamps are placed next to the shrine, and each person can stamp them as they wish.
In any case, the way the visitors treat their goshuin stamps is too sloppy!
It's so messy and dirty that I don't think it's a place where you can receive proof of your visit to the gods.
As a Japanese person, I want to have good manners.
