JP vs KR who's bigget in term of viewership?

the final between zeta and cr reach almost 70k viewership why do riot focus more on the KR region?

i think they haven't got any infrastructure in japan, so it's cheaper to use eng casters in KR than make new casters and studio and carry them to the JP.

3 Reasons Riot is supporting KR more then JP
1) Valorant is struggling to become popular in KR atm, while in Japan it is already popular and receiving lots of viewers

2) KR has had a history to be more competitive in esports then Japan, shown by league and owl

3) The KR scene is more popular with the English speaking communities because they have shown to be competitive in Iceland, along with the most popular player in the Japanese scene being Korean
