Takashi Fukuda, former chairman of Fukuda Electronics Co., who died last August at 81, left some 10.6 billion yen taxable inheritance, Tokyo tax officials revealed Thursday.

Most of the property left by the late founder of Fukuda Electronics, the nation's top maker of electrocardiographs, are in shares of the company and other securities, according to Tokyo's Hongo Tax Office.

Fukuda's widow and four offspring have inherited the property and already paid inheritance taxes totaling a little over 3 billion yen, the sources said.

Fukuda, who was from Chiba Prefecture, founded Fukuda Electronics in 1969.
