I will finally arrive on the Chinese east tomorrow, over three month behind my original schedule. My plan was to take a ferry to South Korea spend a month there and then take a ferry to Japan to travel there for a month. There are ferries from Shanghai to Japan which makes me wonder whether I should go to Japan first and then to South Korea afterwards.
I plan to travel the whole length of South Korea but not much further north than Tokyo.
Is there a significant difference in the climate between the two countries? I would like to avoid traveling in really cold weather.
I plan to leave China around the 25th of September to avoid Golden Week.
So the question is where to go first if I want to avoid cold weather.
