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.

A brewery which holds a prefectural record for winning the gold medal at the Annual Japan Sake Awards for 8 consecutive years. Matsuoka Brewery originated when first generation brewer Matsuoka Emon, in search of higher quality water, moved his brewery from Niigata to Ogawamachi. The brewing water sourced from the Chichibu mountains has a higher concentration of minerals, pumped from a source 130 meters underground. At our brewery tour (reservation required), visitors can view the brewing warehouse, learn about the sake brewing process and enjoy a sake tasting. The Daiginjo (super premium sake) ice cream available at the brewery direct sales shop is a hit with children and adults alike. There is also a brewery restaurant, “Shofuan,” adjacent to the facility.

The Sennen no Sono Lavender Field spans approximately 6.5 hectares and boasts around 22,000 lavender plants including over 10 different lavender varieties, such as Grosso (French), Hidcote (English), and Avonview (Spanish). In late May, visitors can enjoy the enchanting sight of red, pink, and white poppies blooming alongside early-blooming lavender. By mid-June, a portion of the field transforms into a golden sea of wheat known as "Nourin 61," and towards the end of June, visitors can witness the spectacle of wheat harvesting. The annual Ranzan Lavender Festival takes place from early to late June, offering a wonderful opportunity to experience the beauty of the lavender field. *Please note that access to the fields is restricted after the festival as they undergo harvesting.

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.)

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.
