Endless Japan Version 5.0
Everything is the same as 4.0 except castle retainers are reduced to make defending several provinces more difficult.
Fort = 1 Yari Ashigaru
Stronghold = 1 Bow Ashigaru & 1 Yari Ashigaru
Fortress = 2 Bow Ashigaru and 1 Yari Ashigaru
Castle = 1 Yar Ashigaru, 1 Bow Ashigaru, 1 Bow Samurai, 1 Yari Samurai
Citadel = 2 Bow Samurai, 2 Yari Samurai, 1 Katana Samurai
This change may make the start of the game easier to capture some provinces but will make it harder to defend the territory that you capture which will make the game harder later on.
