Bisei Astronomical Observatory-One of Japan’s foremost public obsetvatory-①


Bisei Town, Ibara City, as the name suggests, is the town where you can see beautiful stars and it’s famous for a sacred place of astronomical observations. People in the area have made efforts to protect beautiful stars over the years. In 2021, the town was designated as the third International Dark Sky Place in Japan by International Dark-Sky Association (IDA).


Bisei Astronomical Observatory is in Bisei Town, Ibara City and one of Japan’s foremost public observatories. There is a 101 cm-diameter telescope in Bisei Astronomical Oservatory. You can observe the moon, planets and seasonal celestial objects with the telescope which is one of the most outstanding telescopes in Japan. There are a binocular telescope and small telescope at the observatory and you can observe there, listening to explanations by the staff member. You can also see a shooting star if you are lucky.




I immediately took a commemorative photo at the entrance of the observatory.
