In late March, while engaging in volunteer work and making efforts to restore telecommunications networks in the quake-stricken Tohoku region, Softbank Corp. founder and Chairman Masayoshi Son met with evacuees from the area surrounding the troubled Fukushima No. 1 nuclear power plant.

Days later, he returned to Tokyo and declared pursuit of a new energy policy, one emphasizing renewable sources, such as solar, wind and thermal energy, was needed.

In April, Son announced he would personally donate ¥1 billion to establish a foundation for that purpose.
