The rescue reinforces the Mitsubishi group's reputation as the most tightly knit of Japan's keiretsu: horizontal business groups, anchored by a bank and a trading company, that stick together by holding shares in each other and buying each others' wares. Although the Mitsubishi logo no longer strikes fear into western rivals, the group still boasts a big footprint in lots of industries. Its 29 main companies range from Mitsubishi Chemical and Mitsubishi Electric to Kirin (beer), Nikon (cameras) and Nippon Yusen KK, the shipping company that started it all.
