We're planning to go to Japan and we're torn between flying to and from Osaka, or to and from Tokyo. Reason being is that Osaka has cheaper flights from our country compared to Tokyo Narita. We definitely want to include either Tokyo Disneyland or Tokyo DisneySea (1 whole day), and do some food and culture trips. Is Osaka-Tokyo-Osaka worth the airfare savings or better to just focus on Tokyo and nearby areas? Thanks!
