Fuji Heavy Industries Ltd. President Yasuyuki Yoshinaga has become a market darling for something he failed to do: build a factory in China.

The maker of Subaru cars, the only major Japanese auto brand without a plant in the world's largest vehicle market, has jumped 83 percent in Tokyo trading this year for the biggest gain on the Nikkei 225 stock average.

Fuji Heavy's smaller presence in China helped shield it from a consumer backlash triggered by the Senkaku territorial dispute as its sales in the U.S. and Japan have surged.
