Shingen Mochi Factory Theme Park

The Shingen Mochi Factory Theme Park in Fuefuki City, Yamanashi Prefecture, offers visitors an immersive experience centered around one of Japan's most beloved regional confections. The facility is operated by Kikyouya, a confectionery company that has been producing the signature treat since 1968. The park takes its name from Takeda Shingen, a powerful feudal lord who ruled Kai Province (modern-day Yamanashi) during the 16th-century Warring States period, and whose legacy remains deeply embedded in the region's cultural identity.

Kikyou Shingen Mochi consists of rice cake topped with kinako (soybean powder) and kuromitsu (brown sugar syrup), representing traditional Japanese flavors that have made it Yamanashi's signature souvenir. The confection embodies regional pride and connects contemporary culinary culture to historical heritage. Visitors can observe the production process through windows overlooking the factory floor, where the most distinctive feature is the hand-wrapping technique—each staff member carefully wraps individual servings in approximately 5 seconds, demonstrating remarkable speed and precision that has been maintained as part of the production tradition.

The park's most popular attraction is the all-you-can-stuff experience, where visitors pay just 220 yen to fill a designated bag with as many Shingen mochi packages as they can fit. This activity typically draws long queues from early morning, and quantities are limited, making it advisable to visit early. The facility also features an outlet corner selling near-expiration or slightly imperfect products at reduced prices, offering exceptional value for budget-conscious shoppers. The on-site café serves exclusive menu items including Kikyou Shingen Soft+ (soft-serve ice cream topped with Shingen mochi) and seasonal specialties such as lattes with brown syrup and soybean powder.

From JR Isawa Onsen Station on the Chuo Line, the site is approximately 20 minutes by taxi or accessed via tour services. For those driving, it is a 5-minute drive from the Ichinomiya-Misaka Interchange on the Chuo Expressway. The souvenir shop offers various Kikyouya products, including the ultra-rare Kikyo Shingen Mochi Kiwami, which comes in an edible wafer box and sells out quickly, particularly on weekends.
