Three years ago, Seiho Hayakawa could often be found playing shows at basement venues around Osaka. Today, he's all over the map.

In the past year, Hayakawa has toured the United States, opened for Disclosure in Tokyo and now divides his time between Kanto and Kansai. This Satuday, he'll play the Summer Sonic music festival, to some of the biggest crowds he's seen yet.

"The audiences in America were really quick at reacting to my music — it was easy for them to get into the songs," he says. "It was also easy for them to quickly become indifferent to what I was doing. I gained a lot of confidence from that tour."
