Sennen no Sono Lavender Field

Ranzan Valley is one of Saitama Prefecture's famous scenic spots known for the Iwadatami rock terraces, the clear streams of the Tsukikawa River, and the heavily wooded natural environment. The Hosokawa area has a particularly unique peninsula-like topography, where a large river channel turns at a sharp 180 degree angle. The valley and surrounding Japanese red pine forests are a stunning sight! When Dr. Seiroku Honda, the first person in Japan to hold a Ph.D. of forestry, visited the area, he noted its great similarity to the landscape of Arashiyama in Kyoto, and referring to it as the "Arashiyama of Musashi Province," provided the origin of the name "Ranzan," another way to read "Arashiyama." In the summer, one can enjoy the fresh green and sounds of babbling brooks and chirping birds, in just an unbelievable one hour distance from the metropolis. In autumn you can also enjoy the reflection of the leaves on the surface of the water emphasized by the fiery red of the momiji maple trees. *Peak season for autumn leaves is mid-November to early December.

Overlooking the Toki River to the south is the historic castle ruins site "Sugaya Yakata" (designated a national historic site), said to be where samurai warlord Hatakeyama Shigetada built his mansion in the early Kamakura period (1185-1333), and inside of which exists a museum dedicated to the historic remains of Ranzan Town. The area is also known for its native Mountain Lily (yamayuri), in peak bloom in July. There are also plum and cherry trees. Ranzan Town is home to two of Japan's 100 most famous castles, and together with "Sugiyama Castle," "Sugaya Yakata" was selected for this honor on April 6th, 2017.

Our building is located on the historical site of the Kamakura period samurai palace “Sugaya-yakata” which transitioned to the castle “Sugaya-jō" during the Sengoku period. Opened in April of 1976 as the Saitama Prefectural Historical Data Museum, the museum was later relaunched on April 1st, 2006 for reorganization and maintenance of the prefectural museum facility. Focus was given to the collection, storage, and conducting of research on archaeological materials related to the Sugaya-yakata sites and medieval historical sites such as medieval castle buildings, and to utilize these materials for the development of education, learning, and culture. At that time, the name of the museum was changed to its current name. (For more information regarding the facility, please refer to the URL below.)

In 1970, the “Gogaku Kenshujo Foundation” (village school training institution) was established on the site of the “Japan Agricultural Teachers' School,” founded by Dr. Masahiro Yasuoka in the early Showa period. In 2012, the foundation was officially named the “Foundation for Gogaku Training Institute and Masahiro Yasuoka Memorial Museum” to carry on the tradition of the Japan Agricultural Training School and to promote Gogaku (village schools), as well as to pass on to future generations the much needed teachings and anthropology of Dr. Masahiro Yasuoka.

This barbecue area opened along the river in 2013 is the first in Tokyo to be operated by a private company. Reserve your favorite spot by the Toki River and enjoy barbecuing in the great outdoors!
