Hi,
I'm going to China (Beijing) for 3 weeks in august and, as I have a two entries visa to China, I'm considering jumping to either Seoul or Tokyo for a week, doing mainly city tourism.
I'm mostly interested in tech stuff and futurist cities, I thought Tokyo was more interesting at first, but I have read some reports that, apparently, Seoul is more on the rise in anything related to internet, phones, new technologies, videogames, pop culture and robotics. I am looking for opinions of people who has been recently in both places. I do not speak neither korean nor japanese so availability of English instructions if I buy some stuff is an issue.
Akihabara or Yongsan Electronics market?
Tokyo Museum of Nature and Science or Seoul T.Um museum?
Thanks!
