Perched in a northeastern corner of Akita Prefecture at some 180 meters high sits a Jomon era archaeological site, dating back as far as 4,000 years. Designated as a UNESCO World Cultural Heritage site in July 2021, this spot remains one of 17 “Jomon Prehistoric Sites in Northern Japan”, found scattered across Hokkaido, Aomori, Akita, and Iwate Prefectures.

Travel here to find two large stone circles: the "Manza Stone Circle”, a 52-meter diameter ring made of some 6,500 stones, and the "Nonakado Stone Circle”, a ring of 2,000 stones measuring 42-meters in diameter at its widest point. One trivia point to note is that each stone circle includes a "sundial stone arrangement" positioned to the northwest of the circle's center. Remarkably, when you connect the center of each stone circle to its corresponding sundial stone arrangement, the line aligns with the direction of the sunset on the summer solstice, the longest day of the year in the Northern Hemisphere.

This intriguing destination gets even better with a stop at the You Stone Circle Museum next door, home to a number of beguiling artifacts and their fascinating explanations on display for a deeper look into the history of this place.
