2027 Onariyama Park Starry Sky: A Full-Day Course

Onariyama Park in Tateyama, Yonezawa City, Yamagata Prefecture is a viewing spot introduced on Yonezawa City's official website as a place where “you can enjoy Yonezawa's night view and starry sky, and even the sunrise.” The observation deck's parking lot has space for 6 vehicles (large vehicles cannot park), about 20 minutes by car from the Tohoku Chuo Expressway Yonezawa-Chuo IC, or about 15 minutes from JR Yonezawa Station. Admission is free and the park is open 24 hours, but the roads are narrow with many curves, so visitors driving large vehicles should be careful. Note: during winter, access by car becomes impossible due to snow accumulation (per Yamagata Keikan Monogatari and Yonezawa City official information). Detailed information about nighttime lighting and opening hours could not be confirmed, so please check with the Yonezawa City Urban Planning Division (0238-22-5111) for the latest information.
