This shrine's unique structure has been designated as an important National Cultural Asset.

There are about 180 Japanese Cedar trees standing over 45m high, with an average age of about 200-300 years, lining over 800m of pathway to the shirine.

The great writer, Toson Shimazaki, has nick-named this castle town "Little Kyoto" due to the great number of temples.

"Scattered around the remains of Iiyama Castle are 22 ancient temples and shrines, easily accessible and a pleasant adventure for those seeking refuge from the hustle and bustle of modern life. To remember your temple walk, collect the stamps available at each location. In between visiting the temples and shrines you'll find Buddhist Altar shops, some of where many of the altars are actually made."

Iiyama Castle, located in the heart of the city, was constructed under the order of Kenshin Uesugi, who used this castle as a retreat base during the Battle of Kawanakajima.

The castle was built in a staircase fashion, which made it possible to withhold attacks from Singen Takeda in the 12 years of battle.

In spring, the castle site is famous for the 400 Cherry Blossom Trees (Someiyoshino variety) which bloom all at once.
