Sengoku - Japan's Clan Map

From the Ōnin War of 1467 to the fall of Osaka in 1615, step through Sengoku-period Japan one year at a time.

Move the slider and the provinces change colour as power shifts. Autoplay spends five seconds on each year, so you can follow every change.

WORKS OFFLINE
The map, texts and images are all built in, so it works in airplane mode or with no signal.

Clan colours are shown by modern prefecture and are an approximation, not exact historical borders.
