Four centuries ago exactly, the second Edo Period Shogun, Tokugawa Hidetada, ordered the planting of sugi (Japanese Ceder, Cryptomeria japonica) along both sides of Tokaido to shade travellers as they made their way around the shoreline of Lake Ashinoko towards Hakone Checkpoint. 420 of these magnificant specimens remain, towering straight, fat, and proud into the Hakone sky along Ceder Avenue.
Tokaido had checkpoints at various intervals to ensure that travellers were bonefide and to protect the Shogun in the capital, Edo. Hakone was the closest checkpoint to Edo, so was one of the most severely policed. Perched between the waters of Lake Ashinoko and the steep mountainous terrain of Hakone, Tokaido travellers had no alternative but to submit to inspection.
