Japan trip with Korea stop-over
 

Hi all,

I'm currently trying to plot out my Japan vacation, and I'm trying to see if I can't work out a few days in Seoul while I'm already in the vicinity, so to speak.

My current plans have me in Osaka around the second week of *July. I'm from Canada, so I know I do not need any special visa for my two weeks (flights in and out of Tokyo); however, does anyone know of any limitations that would prevent me from booking a flight from Osaka to Seoul?

Just for clarification, this would have me with tickets of:
Canada -> Japan
Japan -> Korea
Korea -> Japan
Japan -> Canada

Why go to Japan first and then back to Japan again after Korea? Last time I checked it was cheaper to fly directly from the US (I'm guessing the same from Canada) to Korea than it was to Japan. Just go to Korea first and have your flight from Korea to Japan booked for a couple days later.

Due to the slight deal I found, it was actually cheaper to fly in and out of Japan than to Korea, and the Japan flights are already booked. Seoul was an afterthought to be honest.
