Ouchi Post Town is like stepping into a time machine back to the Edo period. With its traditional thatched roofs, running water streets, and over 300-year-old buildings, it's a postcard-perfect glimpse of old Japan. Visitors can slurp on some delicious negi-soba noodles, use leeks as chopsticks, and even learn about Prince Mochihito's local myth. Don't miss the Oza Toro Observation Train for a tatami mat ride through this charming historical gem!
