One sunny Saturday last month, Hitachi Ltd., Japan's largest electronics maker, made headlines when it hosted a rare tour of its spanking new elevator-testing tower — the world's tallest — at its sprawling facility in Hitachinaka, Ibaraki Prefecture.

How exactly does Hitachi intend to take that top spot?
