Waypoint introductions and full write-ups
1. Ōyu Stone Circles
Two great rings of river stones lie in a quiet field on a plateau near Kazuno, in the north of Akita prefecture, and at the heart of each stands a small arrangement of upright stones that has been called a sundial. The Ōyu Stone Circles, known as Manza and Nonakadō, were built by the Jōmon people around four thousand years ago, and they are the largest stone circles in Japan. Beneath and around them archaeologists have found graves, suggesting they were places of burial and ceremony. Some researchers believe the circles were aligned with the setting sun at the summer solstice. Since 2021 they have formed part of the UNESCO World Heritage site of the Jōmon Prehistoric Sites in Northern Japan.

2. Isedotai Stone Circles
In a quiet corner of Akita prefecture, near the town of Takanosu in the north of Japan's main island, a set of stone circles lies on a low terrace above the Yoneshiro river. The Isedotai stone circles were built around four thousand years ago by the people of the Jomon culture, hunter-gatherers who lived in the Japanese archipelago for more than ten thousand years and made some of the oldest pottery in the world. The site is part of the Jomon Prehistoric Sites in Northern Japan, listed by UNESCO in 2021, a series of seventeen sites across Hokkaido and the north of Honshu that illustrate the long, settled life of these people.

3. Shirakami-Sanchi
Shirakami-Sanchi is one of the largest remaining virgin beech forests in East Asia, a vast tract of mountains straddling the border between Aomori and Akita prefectures in northern Honshu. It joined the World Heritage list in 1993, one of Japan's first natural sites, and the core area is left almost untouched, with no roads or facilities. Siebold's beech, a species found only in Japan, dominates the forest, and it shelters black bears, Japanese serows, golden eagles and the black woodpecker. The trees are at their most beautiful in autumn, when they turn gold and copper, and in spring when the new leaves are a startling pale green.

4. Omori Katsuyama Stone Circle
Over three thousand years ago, Jomon people in northern Japan arranged stones into circles on a terrace at the foot of Mount Iwaki, the conical volcano that dominates the Tsugaru plain in Aomori prefecture. The Omori Katsuyama stone circle is one of these monuments, with a ring of standing and placed stones that may have been used for rituals, burials or marking the seasons. It is part of the Jomon Prehistoric Sites in Northern Japan, inscribed on the UNESCO list in 2021, which celebrates a culture of hunter-gatherers who settled in permanent villages and made pottery for over ten thousand years.

5. Kamegaoka Burial Site
In 1887, a farmer digging in the fields near Kamegaoka, in the Tsugaru region of northern Honshu, found a strange clay figure: a stocky body covered with patterns and a face dominated by huge eyes like snow goggles. The shakōki-dogū, the goggle-eyed figurine, became one of the most famous objects of the Jōmon culture, the hunter-gatherers who lived in Japan for more than ten thousand years and made some of the oldest pottery in the world. Kamegaoka was a burial and settlement site of the final Jōmon period, about three thousand years ago, and it has yielded lacquerware, pottery and figurines of remarkable sophistication. It is part of the Jōmon Prehistoric Sites in Northern Japan, listed by UNESCO in 2021.
