Rainbow held two “stamp and handshake” events over the weekend in Japan.

The first one was on March 17 and at the TFT Hall in Tokyo. The second one was on March 18 and held at the Osaka OBP Hall.

The event had 2,100 fans on the first day and 1,300 fans on the second totaling 3,400 fans. Fans had the opportunity to shake hands with Rainbow, and also receive a stamp that was designed by the Rainbow members.

Rainbow’s third Japanese single “Gonna Gonna Go!” reached and stayed at the Top 10 of the Oricon Daily Chart for 3 weeks.
