I doubt there will ever be much subbing for Jdrama because Japanese doesn’t seem to want to promote their country internationally. China is currently taking a leaf from Korean wave that positively promotes Korean culture, food, people and it’s nation through the use of music, drama, movies, pop culture and etc. I used to have to wait for Cdrama subbing for years but they are now subbed within weeks. Plus I am starting to see many youtube channels promoting China dramas. Who knows, we may be able to watch free Cdrama soon without having to pay for subscriptions because it helps to promote China interest globally and also encourage foreigners to pick up Mandarin.
