Ikusa is a board game released in 1986 for 2–5 players, 240–360 minutes per game, and ages 12 and up. It was designed by Michael Gray and its main mechanics are Auction / Bidding, Area Movement, and Dice Rolling.
Ikusa focuses on the chaotic feudal society of Japan during the Middle Ages. Players play one of several factions that erupt into a civil war, trying to consolidate their strongholds and then defeat other armies for the right to be called Shogun, the supreme ruler. In the game, players command forces on islands of feudal Japan. Player forces include provincial forces in the provinces and mobile armies commanded by daimyos. In each turn, players will allocate their koku into bids and purchases for the round. The round begins with the allocation of turn order, which is determined by bid, and in the case of tied bids, by player agreement or random draw. Then players other bids and payments are accounted for in purchases of castles and fortresses, drafting of new troops and ronin, and a bid for the lone ninja. Following the bids phase, players in turn order plan and execute attacks against enemy territories, with attacks resolved through die rolls. A player wins the game when he or she has captured a certain number of territories, either via straight conquest or by vanquishing the last of an opponent's diamyos and taking over that player's forces. The game was originally published as Shogun and was later changed to Samurai Swords due to a name conflict with James Clavell's Shogun. Ikusa is the latest iteration of the game.
Ikusa supports 2–5 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Ikusa is 240–360 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Ikusa for ages 12 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Ikusa has a complexity rating of 3.0 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
