Two new events for the Japanese Pokkén Tournament arcade machines will be running from December 18th 2015 to December 27th 2015 and then from December 28th to January 11th:
This is a joint Christmas and New Year event which features a variety of bonuses. First, if players manage to get Sceptile up to Level 15 before January 11th, they will be given some clothing for their avatar.
In addition to that, if players use a BANA Passport by December 27th they will receive Farfetch’d and Electrode as Support Pokémon and unlock a special Christmas avatar bonus.
This ranges from a Christmas hat to Party hats as well as various Christmas player titles. Finally, a special Santa Claus set of costumes will be available when players log in over Christmas week.
