2AM's Japanese career is off to a positive start, as their nationwide tour sold out every seat within 10 minutes of tickets going on sale. Tickets for the '2AM 1st Japan Tour - Never Let You Go' became available through major ticketing sites on December 17th. Within 10 minutes, tickets for their stops in Tokyo, Nagoya, and Osaka had all been sold out. Considering that 2AM has yet to debut or even promote officially in Japan, the feat is an incredible one that has many looking forward to their potential for success in the market. On January 11th, 2AM will be releasing their debut single, "Never Let You Go", which will contain the Japanese versions of their hit tracks, "Can't Send You Away Even If I Die" and "Sorry I Can't Smile For You". Fans commented, "Wow, all sold out! Amazing since they haven't debuted yet!", and "Finding success in Japan is only a matter of time for them!" 2AM will also be holding their Christmas concert on December 24th and 25th.
