Tatsumi Engeki Box will be on stage in Wakayama, this April.  I inform you living in Tokyo that the cheapest air fare is offered by ANA.  It costs only 8,800.-yen for one way between Tokyo and  Kansai Airport.  Kansai Airport called "Kanku" is closed to Wakayama.  If you have a plan to visit Wakayama in April, please consider this transportation.  You might save costs and time.  However "Super Travel Discount" or Super Tabi-Wari in Japanese is sold two months before your departure.  If you make a reservation in March, it will be the expiration of the time limit.
