I know this might seem like an odd question, but hear me out. :-)
I'm visiting Japan for 3 weeks later in the year and I'm keen to quickly jump over to South Korea for a few days before returning to Tokyo (for my flight back to Sydney).
My (very) rough plan is to be in southern Japan towards the end of my trip so I'm curious to know, which southern city will be the best (cheapest) to fly to South Korea from? Hiroshima? I'd prefer a direct flight rather than flying via Tokyo.
Also, any recommendations on airlines? Asiana are currently the cheapest I've found for that route.
