Masayoshi Son, chairman and chief executive officer of Softbank Corp., was chosen best president of 2011 for the second consecutive year in an online survey of corporate executives in Japan, the Sanno Institute of Management said Thursday.

Son collected 140 votes, or about 30 percent of the total, for his generous donation to victims of the March 11 disasters and for other related activities. He was also lauded for his charisma and plebeian image, the college said.

The survey was conducted by an Internet research firm between Nov. 25 and Dec. 5 and received valid replies from 456 of 541 executives at companies with at least 10 employees.
