The Nayoro Municipal Observatory (affectionately known as 'Kita Subaru') is a public observatory located in Nayoro City, Hokkaido. This facility has a unique history, having originated as a private observatory and currently operating through a collaboration between Hokkaido University and Nayoro City. Its most significant feature is the 'Pirika Telescope,' which boasts a massive 1.6m diameter—one of the largest in Japan. Designed primarily for planetary observation, this telescope is used not only for high-level research but also for public observation sessions and educational tours, offering a rare opportunity to touch the cutting edge of astronomy.
The history of this observatory dates back to a private observatory established by Hideo Kihara, a former high school teacher. In 1992, it was donated to Nayoro City and originally operated as the 'Nayoro Municipal Kihara Observatory.' Since April 2010, under a mutual agreement with Hokkaido University, it has evolved into its current form, the 'Nayoro Municipal Observatory Kita Subaru,' establishing a more advanced system for both research and public engagement. It has long served as a cultural hub for astronomy in the region.
The primary attraction is observation via the Pirika Telescope. This Nishimura Tsusanku-made reflecting telescope is highly specialized for planetary observation, featuring multiple focal points such as Cassegrain and Nasmyth foci, allowing for observations across various wavelengths. Additionally, the facility is equipped with a planetarium and various exhibits related to celestial bodies, allowing visitors to visually learn about the mechanics of the universe. Depending on the timing, the observatory may host special sessions for significant astronomical phenomena, such as the discovery of supernovae or detailed observations of Venus.
Observatory activities are primarily centered around nighttime observations and specific celestial events. For instance, during the summer, special events like the 'Tanabata Stargazing Session' may be organized. Observations are also tailored to specific meteor showers or notable astronomical phenomena. During the day, visitors can deepen their astronomical knowledge through telescope tours and facility exhibitions. Please note that schedules for observation sessions fluctuate based on the season, weather, and celestial conditions, so checking in advance is highly recommended.
The facility hosts a diverse range of programs beyond simple stargazing, including musical live performances and specialized observation sessions. For example, there are events that combine live music with the starry sky, or sessions specifically timed for meteor showers. During non-observation hours, educational programs are available to teach visitors about the structure of the Pirika Telescope and the mechanics of planetary observation. It is a precious opportunity to learn about the universe using professional-grade equipment.
The Nayoro Municipal Observatory is located within the 'Hoshimi no Oka' (Star-viewing Hill) area of the Hokkaido Sun Pillar Park. This environment is ideal for observing the stars amidst rich, untouched nature. Visitors can enjoy the natural beauty of Nayoro while participating in astronomical activities or simply taking a peaceful stroll.
Please check the official website for details regarding facility use and specific events. The availability of cash or credit cards depends on the type of event being held.
While some English signage may be available, the level of detailed English explanation by staff varies depending on the event and the season.
It is highly recommended to check the schedule and make reservations for observation sessions or special events (such as music lives). For tours or observations outside of standard observation hours, please confirm the dates and times on the observatory's official website.
If you are participating in nighttime observations or outdoor events, heavy winter clothing is essential to prepare for the cold Hokkaido nights. Please ensure you bring appropriate seasonal gear to stay warm.
