Keikyu Corp. on Monday began operating a special "Love Train" to promote Valentine's Day.

The Keikyu Love Train, featuring four nonreserved box seats decorated with heart designs, will run through March 14, according to the Tokyo-based railway.

In Japan, Valentine's Day falls on Feb. 14 but is marketed as the day on which women are to give chocolates to men, while White Day, a local invention designated for March 14, is marketed as the occasion for men to return the favor.
