Château d'Arato

Château d'Arato is a mountain fortress near Chikuma with structures positioned along a high ridge below Mount Kamuriki, overlooking steep terrain above the Shinano River. The site features defensive walls, watchtowers, and reconstructed buildings arranged across multiple levels of the terrain.

The fortress was founded in 1524 by the Yamada clan and changed hands several times during disputes between the Takeda and Murakami clans before losing importance around 1584. The strategic location along a mountain ridge made it valuable throughout these periods of regional conflict.

The reconstructed buildings here reflect how soldiers and officials once organized their daily routines within a mountain stronghold. Walking through them, you can observe the layout of traditional military spaces built according to samurai-era construction methods.

The site is most easily reached by taxi from the nearest railway station, which is about a 20-minute drive away. Wear comfortable walking shoes since exploring the ridge-top grounds involves walking across uneven mountain terrain.

The site was transformed in 1995 from a former park into a historical theme park, with most structures rebuilt based on archaeological findings and historical records. This reconstruction effort allows visitors to experience the fortress much as it would have appeared during the samurai era.
