TVXQ has officially started their Japan Tour, which is expected to be a huge success. The tour is expected to have at least 450,000 fans in attendance.

Their first stop on the tour was at the Yokohama Arena in Japan, which took place on January 18th. Their 'TVXQ Live Tour 2012 Tone' will have the group traveling to 9 different cities and will have a total of 24 performances.

This has been a long time coming for TVXQ as it has been three years since their last independent Japanese Tour. They were out there performing song off of their full-length album 'Tone,' which was released last year.

They left fans wanting more as they could be found cheering and yelling at the top of their lungs as Yunho and Changmin performed their hearts out.

Also during the performance they decided to surprise their fans with a new unreleased song.

Changmin told fans, " We are going to sing a song that we've never sang before."

The new song "Still" will be included on their new album that drops on March 14th. When the crowd heard the new song, they were filled with excitement and surprise causing the arena to go wild with loud cheers.

The next stop on the tour will at the Tokyo Dome on April 14th and 15th, and they will also be stopping by the Kyocera Dome on April 21st and 22nd.
