Less than five minutes into art group Maywa Denki¡¯s 25th anniversary show on April 14 at Square Ebara Hiratsuka Hall in Shinagawa, Novmichi Tosa, the lead member of the group, has the full house giggling ¡ª and they haven¡¯t even seen him yet.

It¡¯s pitch black and Tosa¡¯s grand entrance has proved to be less of the anticipated glorious bang than a few comically erratic ¡°pops,¡± accompanied by diminutive sparks of light.

A soft apologetic voice finds its way out of the darkness: ¡°I think my battery has run out ...¡± And the giggles finally erupt into laughter.
