The Industrial Revitalization Corp. of Japan announced Monday that it has decided to bail out Mitsui Mining Co. under its resuscitation program.

The decision means the state-backed corporate revival body now has four cases in hand.

The IRCJ had announced Thursday that it would try to bail out three other ailing firms: Tokyo condominium builder Dia Kensetsu Co., Kumamoto bus operator Kyushu Industrial Transportation Co. and the Usui department store in Koriyama, Fukushima Prefecture.
