The nation's largest discount travel agency, HIS, which also runs foreigner-friendly No.1 Travel, has based the price of some air tickets from Japan on the nationality of the traveler, possibly in breach of Japanese law, The Japan Times has learned.

Foreigners trying to buy discount tickets through the company were quoted higher prices than Japanese customers purchasing discount seats on the same flight.

The policy came to light when the company offered a discount ticket to Los Angeles over the telephone to a Japanese caller, but said it was no longer available at the quoted price after finding out a Canadian was the intended traveler.
