It is the area called Okusaga.  Its peaceful scenery is reminiscent of the old days when people used to come and go, and the emperor Saga cherished the idyllic landscape and tranquility of this area. 

The temple was built by Ashikaga Takauji to console the spirit of Emperor Godaigo. The Sogenchi Garden, a World Heritage site, was created about 700 years ago by Muso Kokushi (a Zen priest of the Rinzai sect), for whom creating a garden was an ascetic practice.   Incorporating Kameyama and Arashiyama as backdrops, the garden attracts visitors with its charms changing every season. There are many highlights in the pricincts, such as the Unryu-zu, a large dragon drawn on the ceiling of the dharma hall.

Exiting the north gate of the temple, you will find a path that goes through the bamboo grove.  The area was allegedly popular as the noble's vacation villas in the Heian period (794-1185).   The sunlight filtering through the bamboo feels pleasant on a sunny day.

he area used to be a hunting ground for the court nobles. Daikakuji Temple was the former imperial detached palace in the 9th century and then changed into Daikakuji Temple.  The graceful architecture of the Shinden-zukuri (nobility’s residence) style and the elegant mural paintings of birds and flowers will bring you the noble air of the Heian period (794-1185).  The peaceful and panoramic view around the Osawa Pond is breathtaking, especially during the cherry blossom season in spring and the colored foliage season in autumn.  If time allows, try your hand at sutra copying or Buddhist image tracing in honor of Emperor Saga, who excelled in calligraphy.

Tucked away off the main road stands Gio-ji Temple, surrounded by brushwood fences.  Together with the tragic episode of the dancer Gio, the seasonal changes in scenery created by the moss garden and maple trees embody the true Japanese sense of beauty.

Located at the north end is Otagi Nenbutsu-ji Temple, which has been quietly booming among tourists in recent years.  In the precincts, 1,200 Rakan statues with unique facial expressions await you.  They were chiseled by people who responded to the call of the former chief priest, who was also a Buddhist sculptor and restorer when he moved the abandoned temple to this site.
