SNSD will have their first arena tour concert in Japan on May 18th. The tour will start at Tokyo's Yoyogi stadium, and then move onto Nagoya, Osaka, and then onto Fukuoka. Considering their first showcase before their official debut in Japan attracted over 22,000 viewers, this tour is expected to be a battle for tickets.
