Prosecutors on Wednesday indicted five former executives of the failed Tokyo Sowa Bank on charges of conspiring to falsely show the bank had adequate capital reserves.

Shoichi Osada, 77, chairman of the Tokyo-based second-tier regional bank when the suspected book manipulation took place, was indicted, along with Mizuho Kojima, 60, former president, and Masatoshi Fukui, 56, former vice president.

Prosecutors also indicted Hiroyasu Ebisui, 57, former senior managing director, and Tachiki Takahashi, 47, former managing director. They were arrested earlier this month.
