A government panel approved a plan Wednesday to build a magnetically levitated train line over the shortest proposed Tokyo-Osaka route.

The panel at the Land, Infrastructure, Transport and Tourism Ministry gave the green light to a midterm report that states Central Japan Railway Co. (JR Tokai) is responsible for constructing and operating the route on a virtual straight line through the Southern Alps.

Because it has a more favorable cost-benefit ratio, the panel favors that route over other proposals that would divert the line north of the mountain range.
