If it doesn’t succeed on Japanese market, it maybe a hard time to carry your project on.
Many Koreans already recognize NEM as something out of Japan or Japanese, they don’t hate it but they don’t like it (I like both Japan and Japanese), but once it shows a sign of success in Japanese market, like being listed on Japanese exchange, they will be mad for taking market share out of Japan I promise.
Recent pumping on Stratis and Syscoin were accelerated by Koreans, they just put their money in simply because everyone else did, like when they did the same on Ethereum Classic. Pumping on Ethereum Classic was started by a bait for new users in a forum in Korea.
