The story
At the spring and autumn equinoxes, the sun rises over Mt Miwa, passes over Mt Nijo and sets in Osaka Bay, which is why the straight east-west road beneath it is called the road of the sun. Laid out in 613 under Empress Suiko, the great road linked the diplomatic port of Naniwa to the capital at Asuka, about 40 km in all. Envoys from China and Korea brought Buddhism and new technology along it, and Prince Shotoku and others built temples by its side.
In the Middle Ages the road tied together two trading cities at its ends: Sakai, a self-governing port the missionary Luis Frois called the Venice of Japan, and Imai-cho. Later it carried pilgrims to Ise.

Good to know
- Sakai is famous for its kitchen knives; a forge or knife shop makes a good stop.
- Sakai's tea culture, spread by Sen no Rikyu, lives on in its old sweet shops.
- Walk one section rather than the whole road; the mountain stretch near Mt Nijo feels the most ancient.
