Gutei Observatory is located in Samukawa, Shikokuchuo City, Ehime Prefecture, at an altitude of approximately 350 meters. The greatest charm of this location is the overwhelming 180-degree wide-angle panorama. The dynamic night view, created by the calm waters of the Seto Inland Sea, the cityscape of Shikokuchuo, and the distant, glowing industrial clusters of the Iyo-Mishima area, is truly breathtaking. Beyond the night scenery, the daytime offers a grand natural landscape featuring the islands of the Seto Inland Sea and the mountains of Sanuki. Furthermore, during the winter, the area comes alive with seasonal light displays, such as the approximately 100,000 LED lights illuminating the streets near the Mishima-Kawanoe IC.
The observatory was completed in 1961 and has long been cherished as a local landmark for its scenic beauty. Its significance was officially recognized when it was selected as one of the '100 Best Night Views in Japan' in 2004 and as part of the 'Japan Night View Heritage' in 2010. Additionally, in 2012, it was designated as a 'Lover's Sanctuary,' establishing its history as a romantic destination for couples. It stands as a symbol of the coexistence between the region's natural beauty and its industrial heritage.

The primary highlight is the spectacular light panorama that unfolds at night. The combination of city lights, the powerful glow from the industrial plants, and the light reflecting off the sea creates a truly mystical atmosphere. On clear nights, the starry sky can be just as stunning as the night view itself. During the day, you can enjoy the beautiful contrast between the islands of the Seto Inland Sea and the Shikoku Mountains. In winter, the seasonal illumination of the street trees adds a magical touch, making it a highly attractive destination for a scenic drive.
Since the main attraction is the night view, visiting after sunset is highly recommended. The atmosphere is particularly enchanting at night when the city lights are most vivid. The winter season is also a popular time to visit to see the seasonal illuminations. On clear nights, you can experience the breathtaking combination of a starry sky and the urban light display. During the daytime, the best time to visit is when the sunlight highlights the deep blue of the Seto Inland Sea and the seasonal colors of the landscape.

Visitors can enjoy a relaxing stroll while taking in the panoramic views or use the area as a scenic stop during a drive. A popular tradition among couples is to hang
