Preparación
1. Choose a game mode: (A) Austere – Samurai module; (B) Basic – Samurai + Tenno's Court; (C) Classic – Samurai + Tenno's Court + Military Leaders; (D) Daimyo – all four modules. 2. Player 1 takes Yellow + Blue Alliance boards; Player 2 takes Purple + Black Alliance boards. 3. Use the Sun side of the game board (3 regions, 27 provinces in light green, violet, and tan). 4. Configure individual boards front-side: 1 full board (Yellow or Purple) plus the right part of the allied color board (Blue or Black) showing 3 additional action columns. 5. Each player has 11 countryside areas (7 on main board, 4 on allied board: armies of 4, 3, 2, 2). 6. Each player receives: 1 Daimyo card, 5 Chest cards, and 3 Battle Tower cards (from Tenno's Court). 7. Initial Chests: 18 in Austere mode (A); 21 in Basic mode (B). 8. Set aside 1 Permanent Event card (neutral provinces always enter battle with 2 green cubes) – place it visibly or place 2 green cubes on empty provinces as a reminder. 9. Set aside 3 Special Event cards: two rice confiscation and one "min. 6" tax collection card – used in the 1st Winter round. 10. Shuffle 8 regular Event cards (0 to -7 Rice loss), excluding special and permanent cards. 11. (Optional Thematic Variant): Player 1 receives Aki card with a Castle, yellow military leader, and 5 yellow armies. Player 2 receives Owari card with a Castle, purple military leader, and 5 purple armies. 12. Shuffle 27 province cards. Draw 1 per region (3 total); place 2 green cubes and 1 Revolt marker on each to mark them as neutral starting provinces. 13. Load the Battle Tower with 7 yellow cubes, 7 purple cubes, and 10 green cubes. 14. Determine First Player: the player with the most armies on the tower tray goes first. On a tie, Player 1 goes first in the thematic variant; otherwise the weakest player goes first. 15. First Player places their Daimyo card on turn order position 1; second player on position 2. 16. Return all cubes from the tower tray to supply. 17. First Player begins claiming starting provinces; each player claims 11 provinces total. 18. The 2 unclaimed provinces may have 2 green cubes placed on them. 19. Daimyo mode only: Shuffle the 3 Region tiles (Chambers module) and place them on turn order positions 3, 4, and 5. 20. Tenno's Court module: Shuffle Favor cards, place deck face down next to the board (used in First Winter). 21. Samurai module: Arrange 7 cards as a column/row bonus path (3-2-1-empty-1-2-3) between players; place 2 red court officials on the "empty" card. 22. To mark board limits, optionally place a red court official on adjacent provinces not part of the game (next to tan provinces).
