Waypoint introductions and full write-ups

  1. 1. Fuel stop near Yokosuka

    Yokosuka occupies much of the Miura Peninsula, south of Yokohama, and it has been a naval town since the 1860s, when the Tokugawa shogunate built a shipyard here with French help. Today it is home to the US Navy's Seventh Fleet and a major Japan Maritime Self-Defense Force base, and the mix of cultures gives the town a distinctive feel. Dobuita Street, near the base, is full of bars and shops, and Yokosuka navy curry is a local speciality.

  2. 2. Atami

    Atami is a hot-spring resort on the eastern coast of the Izu Peninsula, a town that climbs the hillside above Sagami Bay in a tumble of hotels, apartment blocks and narrow streets. It has been a place of rest for centuries, and the shogun Tokugawa Ieyasu is said to have visited for the waters. Today the town is quite easy to reach from Tokyo, with a bullet train stopping here, which makes it a favourite weekend escape, and it still has a faintly retro seaside air, with old inns, souvenir shops and steaming vents.

  3. 3. Scenic stretch near Ōtsuki

    Ōtsuki sits in a deep, narrow valley in the mountains of eastern Yamanashi, where the old Kōshū Kaidō highway from Edo to Kōfu meets the road south towards Mount Fuji and the Fuji Five Lakes. The Katsura river runs through the valley, and steep, forested mountains rise on every side, giving the town a closed-in, mountain feel despite being only about an hour from western Tokyo.

  4. 4. Photo stop near Yoshii

    One of the oldest written stones in Japan stands near Yoshii. The Tago stele, carved in the early eighth century to commemorate the creation of a new district, is part of a group of three ancient monuments in the area that were added to UNESCO's Memory of the World register in 2017. It is a modest stone under a protective roof, but its age and significance give pause in a landscape of fields and low hills.

  5. 5. Kashima-shi

    Kashima's great shrine claims to be one of the oldest in Japan, and its deity, Takemikazuchi, is a god of thunder and swords. A stone in the shrine forest, the kaname-ishi, is said to pin down the head of a giant catfish beneath the earth whose thrashing causes earthquakes. Only a small rounded top shows above ground; legend says that no amount of digging has ever reached its bottom. The forest around the shrine, with tall cedars, deer and a spring-fed pond, is a cool, dark refuge on a summer day.
