150 pounds less and closer to you? Sounds like a bargain to me, though I haven't flown either airline. I did fly some other "bargain airlines" though (Korean Air, for instance), and it wasn't bad at all. Sure, the food may be a little cheaper than JAL or something, but for that kind of savings, it's more than worth it IMO.

Also, you may want to consider just what you want to see and do in Japan. Many people (including myself) who have been to Japan actually prefer the Osaka/Nara/Kyoto region, as it has more things to see and do than Tokyo. You can always buy a rail pass to take the bullet train, or take a night bus, to the Kansai region from Tokyo, but if you fly into and out of the Kansai International Airport near Osaka, you don't have to bother with any of that. If I were to go back to Japan, that's definitely what I would do. I mention it because you haven't bought your tickets yet, so you have a chance to consider and look into it.
