In the Japan half of the expansion, some routes are reserved for the Bullet Train network, and once such a route is claimed, it can be used by all players to complete destination tickets. To claim such a route, discard a number of cards equal to the length of the route with all the card being the same color, then mark the route with a single Bullet Train miniature; instead of scoring points for such a route, advance your marker on the separate Bullet Train track as many spaces as the length of this route. At the end of the game, whoever has contributed the most to this shared project receives the largest bonus, with the player who contributes least being penalized.
This game board also has a small inlay for the Tokyo subway system, so players are effectively working on two networks at once. You might have a ticket that lists a city outside Tokyo and a station with Tokyo, and you need to complete a route from that other city to Tokyo, then from the central Tokyo station to that particular subway station.
The board also introduces a new type of ferry route. On this game board, all gray routes are ferry routes, with these routes having 1-4 spaces marked with a wave symbol. To cover a wave symbol, you must play a locomotive or a ferry card from your hand (in addition to the other cards needed to claim this route); a ferry card is a special type of card that can be drafted on its own on your turn, and it contains two wave symbols, so it can be used on its own to cover two symbols on a route.
The player trains and game cards from Ticket to Ride or Ticket to Ride: Europe are needed to play this expansion.
Rules for both game boards are live on the Days of Wonder website. In a press release announcing this expansion, Moon says, "With this expansion, players will discover two very big maps. However, while Italy does really play big, Japan feels very fast and small because of the Bullet train variation. I hope that means it has something for everyone!"
Ticket to Ride Map Collection: Volume 7 – Japan & Italy will debut at SPIEL '19 in October ahead of a retail release in Europe in November 2019 and in the North America in January 2020. This expansion retails for US$40/€40, and the Italian market will have a special edition of the game in which the countries highlighted on the box are flipped. Smart idea!
