Delta is offering round-trip flights from Houston (IAH) to Tokyo (NRT) for $653, with a connection. Flights SUN-THU September to November.
Note: We’ve seen this on sale last April for cheaper. There is a good chance that this price will continue to drop. If you book this fare and the price drops, you should be able to cancel within 24-hours after your purchase on most booking sites.
Warning: Pay attention to the departing and returning airports. The cheapest fares may arrive in HND and depart from NRT or vice versa.
