Bisei became the first town in Japan to implement a Light Pollution Prevention Ordinance in 1989, making it the perfect place to have these star-gazing facilities. The Bisei Astronomical Observatory was built in 1993, and then in 2000 the Bisei Space Guard Centre was completed, an important asset to the Japan Aerospace Exploration Agency (JAXA).
This means that Bisei is the perfect place to watch the stars, even with the naked eye. It's from this strong association with the night sky, that Bisei became known as the 'Town of Stars', and the name Bisei as well in fact, means 'Beautiful Stars'.
