Healing Night Event 'Sleeping Planetarium' in Yokohama: Journey Through 88 Constellations from Tanabata

Konica Minolta Planetaria YOKOHAMA (operated by Konica Minolta Planetarium Co., Ltd., President & CEO: Yumiko Hon) will hold a special event, 'Sleeping Planetarium: Journey Through 88 Constellations from Tanabata,' for a limited 7-day period from Wednesday, July 1, 2026, to Tuesday, July 7, 2026. This event allows adults to enjoy a healing moment unique to a summer night by gazing at the stars in the planetarium while listening to a live narration.

★A Relaxing Moment Listening to Constellation Stories in the Planetarium

The 'Sleeping Planetarium' is an event held on November 23, 'Labor Thanksgiving Day,' at planetariums nationwide, primarily for those who work or study hard every day, allowing them to rest while stargazing. It was also held at Planetaria YOKOHAMA last October and was well-received. This time, for the seven days leading up to Tanabata, the staff will provide a live-narrated journey through the starry sky, starting from Yokohama.

★A Journey Through 88 Constellations Starting from Tanabata

After listening to the story of Tanabata, you will shift your gaze to the summer night sky and journey through the stars as the seasons change. Furthermore, you can enjoy a special experience where all 88 constellations in the entire sky appear one after another as you move to the southern hemisphere's sky.

Enjoy a peaceful time quietly gazing at the starry sky, interwoven with the narration of myths related to the constellations. We offer a luxurious time away from your daily life.
