March 13th marks the third anniversary of the opening of the Tokyo One Piece Tower. The park will be celebrating in style with a variety of activities and exclusive merchandise. Leading up to the anniversary, two special events will be held on March 9th and 10th. Both days will have a “talk show” highlighting the tower’s three years as well as various photo opportunities. Sanji’s Buffet Restaurant will also host a dining event with a third anniversary menu. March 9th is also the start of a thank you gift campaign. Visitors will receive an exclusive comic called Volume 333 with the purchase of a “Live & Park Pass”. The comic which gets its name from the third anniversary as well as the height of the Tokyo Tower (333 m) will be about the One Piece Tower and promises some “behind-the-scenes stories.” Volume 333 will have a limited run of 50,000 copies and will be available while supplies last. read more http://www.onepiecepodcast.com/2018/02/07/tokyo-one-piece-tower-third-anniversary/
