Both Japanese and Koreans use Facebook and line in China. You need the next software to get in, otherwise you can't get in. To use Facebook, you need to download a disguised geolocation software. Change your location to Korea and search for people nearby. Add friends online. It can be added in official website. The following are comments written by Japanese and Koreans. Just add it. There is also the need to enter a website called recruitment board to add friends. This is the most common way. There are accounts, photos and addresses in it. Just copying the accounts. I don't know. The website can be searched online. Or download the APP version of the fundraising board.
