In Oyama, historical traditions and archaeological traces meet a large wetland on the city’s southwestern outskirts. You can choose different focuses for your trip: Tokugawa history, Jōmon culture, a Yūki-tsumugi experience, or nature observation and cycling in Watarase. The topics below will give you a concrete sense of what makes Oyama distinctive.
Tokugawa History and Former Fortifications
The Oyama Hyōjō was an important military council. According to tradition, it took place in Oyama in 1600 and paved the way for three centuries of stability under Tokugawa rule. The Oyama Goten has been mentioned since 1622 as a place for rest and overnight stays during the Tokugawa family’s visits to Nikkō; the Oyama Hyōjō served as its model. Both historical connections link Oyama with the political history of the Tokugawa period.
A local founding legend also reaches far back: In Oyama, Fujiwara no Hidesato is said to have founded Suga Shrine in 940 after bringing a deity there from Kyoto’s Yasaka Shrine. Deep moats and high earthen ramparts remain at the former castle site of the Oyama clan. These fortification traces offer a different perspective from the events preserved in tradition: here, the former castle grounds are defined by their earthworks.
Hands-on Jōmon History
The Terano East Site archaeological site combines a remarkable discovery with hands-on activities. Water-use facilities were discovered in a Jōmon-period stream in a concentration unique in Japan. The site’s information center has activity areas for a Jōmon pottery puzzle and trying on earrings. Alongside its archaeological significance, the site offers concrete activities—a different way to approach history than through Tokugawa traditions.
The Watarase Floodplain
The Watarase Floodplain, a Ramsar wetland, lies on the southwestern outskirts of Oyama. About 260 hectares of the second retention basin are within Oyama City, equivalent to around 7.9 percent of the area’s total. These figures refer to the city limits and give an idea of Oyama’s share of this extensive landscape.
Birdwatching, plant observation and cycling are possible in the floodplain year-round. This focus on nature differs from the city’s historical and archaeological themes: you can orient your trip more toward observing the landscape or visiting cultural sites. The activities listed are not limited to a particular season.
Explore Oyama by Rental Bicycle
O-cycle was set up for leisurely rides around the city based on the “sansō” concept. It uses NoiS Model-T bicycles with small 20-inch tires and an easy pedaling feel. Rentals are available at two locations: the Oyama Tourist Information Center and Machi-no-Eki Shikisai-kan. The bicycles complement the year-round activities in the Watarase area, without implying a particular route.
The Oyama Tourist Information Center is listed as open for rentals Tuesday through Sunday, 9:00 a.m. to 5:00 p.m. The center is closed from December 29 to January 3; if a public holiday falls on a Monday, it is closed the following day. Check these details before your trip, as opening hours may change.
Yūki-tsumugi: A Hands-on Craft Experience
During a Yūki-tsumugi experience, you can wear a kimono made from this UNESCO-recognized intangible cultural heritage. The yarn is spun by hand, and the fabric is handwoven by experienced craftspeople. With an advance reservation, you can also wear the kimono outside the venue after getting dressed. If you take it for a walk around the city, you must return it to the Craft Center by 3:30 p.m. Confirm your reservation and any seasonal conditions in advance.
Oyama’s options range from historical stories and hands-on archaeological activities to crafts and nature observation. As you plan your trip, consider which of these focuses appeals to you most.
