Okayama’s city core, Korakuen Garden and the black-walled castle facing it across the Asahi River, is honestly about one day of sightseeing. Most rushed itineraries try to bolt Naoshima’s art islands onto a second day anyway, and the ferry timing plus the museums’ mandatory advance reservations make that a real trap, not a shortcut. This plan spends day two 15 to 17 minutes away in Kurashiki instead, whose canal quarter regularly outshines the city it’s a day trip from.

Okayama’s city core, Korakuen Garden and the black-walled castle across the river from it, is honestly about one day.

Need less time? See the 2-day through 6-day versions instead.
