They advertise 2 hours, in practical terms you should allow at least 3 hours for the results to come back.
Thank you for the feedback. I attempted to contact the testing clinic but didn't get an answer. I guess I'll just have to quarantine upon arrival to Hawaii from Bangkok, unless someone has any other information. I would assume that the clinic at Haneda is land side as well? Looks like it from what I can tell.
