Traditional Japanese festivities and sixteen new travelers are now part of the wonderful Tokaido journey, with these matsuri (the Japanese word for "festival") being triggered by the arrival of the travelers at the intermediate inns, punctuating the path with new and unique events.
Matsuri is a Tokaido expansion that brings new cards and tokens to the game. With this expansion, the players live the Japanese feasts and festivals. These cards modify the way each section of the road is played. This doesn't transform the game, but adds even more depth and strategy in the same way that Crossroads did.
