With the War Phase over, there is some cleanup that must be performed before moving on to the next Season:
Discard Coins and Ronin – All Coins and Ronin tokens in players’ reserves are returned to the common pile. They will need to rebuild their resources again next Season.
Return Shinto – All figures on the Shrine tiles are returned to their owners’ reserves. They will need to send them worshipping again next Season. Note that all figures on the Map remain there from Season to Season.
Return Political Mandates – Take the Political Mandates that are on the board and shuffle them back with the deck of Political Mandates which should be close to the player to the left of the one who performed the last Mandate Turn this Season.
The next Season then begins with its Seasonal Setup step.
