Yokohama

Setup: Remove the specified districts and management boards for 2/3/4 players, arrange the city randomly, and add building tiles, five-power bonuses, and three achievements. Prepare technology and order markets. Keep warehouse pieces separate from available pieces, and take starting assistants, shops, goods, money, and one chosen order. In two-player games, block marked Church/Customs spaces with an unused color.

Turn sequence: Take additional actions, the main action, then additional actions again. Additional phases allow any number of eligible orders and achievements and at most one Foreign Agent across the whole turn. The main action places assistants, moves, performs an area action, takes a five-power bonus, optionally builds, and recovers assistants.

Place assistants: From hand, place up to one assistant in each of three different districts or two in one district. Do not use warehouse or management-board assistants directly. For every assistant placed in a district containing opposing Presidents, pay each relevant opponent one yen. Assistants cannot enter the Canal.

Move the President: From hand, place directly at a legal destination; from the city, move through adjacent districts containing your assistants. A normal destination needs your assistant and no opposing President, and you cannot return to your starting district. Passing opposing Presidents costs one yen each. The Canal has its own paid crossing rule.

Power and construction: Your assistants, President, shop, trading house, and the Station each contribute one power at the destination, capped at five. Resolve the corresponding area effect. A five-power action takes any remaining local bonus. At four or more power, build one shop or trading house from hand; each player may have one shop per district, and only one trading house is available there overall.

Recover or withdraw: After an area action, return all your assistants there to hand, leaving buildings and President. Alternatively, at movement, return your President and any district assistants to hand, excluding management boards. Skip the remaining main-action steps but retain the second additional-action phase.

Trade and technology: Production districts yield copper, silk, tea, and fish. Ports supply orders: keep at most three and never discard them for space; pay the required goods to complete one. Laboratories buy technologies using power plus optional money/imported goods, with no duplicate titles and an extra charge from the fourth onward. Card text can modify general rules.

Achievements and agents: Place an assistant from hand to claim a qualifying achievement; first place pays more, and each is once per player. Each matching country-icon pair across technologies and completed orders can earn an available Foreign Agent. Flip an agent to act in a district with your assistant but not your President, resolving action, bonus, construction, and recovery while ignoring opposing-President fees.

End triggers: A player builds all four trading houses or eight shops, order replenishment cannot fill the market, or either Church/Customs board reaches 5/5/6 assistants for 2/3/4 players. Count blocking unused-color assistants in two-player games. Complete the current round, then play one complete final round.

Final score: Add Church first/second bonuses of 6/3, Customs 8/4, technology total-production ranking 10/5, and country sets. Sets of 2/3/4/5 different countries score 2/4/8/12; each icon belongs to one set. Unused agents and imported goods score one each, every two yen scores one, and every three trade goods scores one. In two-player games, the dummy competes for Church/Customs majorities and has a fixed total production value of 7.5 for technology ranking. Highest total wins; ties favor earlier order starting with the first player.
