Singapore may have just added a new tech billionaire, but it had to lure him from Japan first.

Taizo Son, who built his fortune on hit smartphone game ¡°Puzzle & Dragons,¡± has relocated to the city-state from Tokyo and plans to invest $100 million (about ?11 billion) in Southeast Asia within five years. The younger brother of SoftBank Group Corp.¡¯s founder said in Singapore he¡¯d become frustrated by regulations in Japan as well as the country¡¯s education system.

¡°I tried very hard by lobbying the Japanese government: ¡®Why don¡¯t we have a regulatory sandbox to bring some innovative ideas?,¡± ¡® Son told the event arranged by the private bank of DBS Group Holdings Ltd. ¡°But the country¡¯s too big and very slow to move. But here, even the government, regulators are innovation-minded.¡±
