In line with the trial increase in train services from November 2000, the "TSUNAMI Squad" was formed, consisting mainly of young people living in Hiroshima City and local residents.

The goal was to have Keisuke Kuwata visit Tsunami Station, attract many Southern fans, and keep the Kabe Line running.

They also sang "TSUNAMI" at events, and were featured in many local media outlets as a central activity in the Kabe Line survival movement.

In fact, Keisuke Kuwata, the band's frontman, covered this issue on his radio show , but he never sang at Tsunami Station.

Even after the partial closure of the Kabe Line, the TSUNAMI Team continues to engage in exchange activities with local residents as of February 2011.
