Group FTISLAND expressed their happiness while on their Japan arena tour.

Member Lee Hong Ki recently posted on his twitter, "I am happy. Thank you so much," and posted a picture from the 'FTISLAND Arena Tour 2013-FREEDOM' first concert at the Sendai concert.

In the picture, the members are all sweating and yet showing their gratitude to their fans.

Leader Choi Jong Hoon stated, "Because the first concert went so well, we are still reminiscing about it. We know that the rest of arena tour is going to be great because we started off on the right foot."

He added, "We also prepared long and hard for this concert and we are so happy to see that everything is falling right into place."

Other members of the group stated, "While preparing for this concert was not easy, we have no regrets as we were able to show our fans our true rock side. We were really able to feel and remember that having all five members together really creates a positive energy on stage."

FTISLAND will now continue on to other cities until July and meet with 100,000 fans along the way.
