The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method.

Airport limousine buses (e.g., Kintetsu Bus) serve Osaka Uehommachi, Doton Plaza, and Universal Studios Japan, offering a comfortable alternative with luggage assistance. Taxis and rental cars are available but are generally slower and much more expensive for the ~50 km trip; ride-sharing is extremely limited in Japan.
