Tosa Kaidō
The Tosa Kaidō (土佐街道) was an ancient trade route in Japan that is now mirrored by the modern National Route 33.
History
[edit]The Tosa Kaidō was established during the Yamato period.
The Tosa Domain used a route that connected Kōchi with the modern-day Shikokuchūō sankin kōtai. This route was called the "Old Tosa Kaidō" (旧土佐街道 Kyū-Tosa Kaidō).
It developed into an official highway during the Meiji period, before being renamed the Prefectural Matsuyama-Kōchi Highway (県道松山高知線 Kendō Matsuyama-Kōchi-sen).
On January 18, 1945, it was renamed as National Route 23, before becoming National Route 33 on December 4 of the same year.
