Display MoreIt's a super huge market, just below USA
They dont need to expand their wings to other countries. Japan has strong buying culture when it comes to music. They are slowly transitioning to streaming but buying physical album culture is still very strong. Japanese groups such as Arashi, Johnny's, EXILE, AKBgroup, Sakamichi46, =Love, Momusu, etc are king and queens in their own country. They have solid and strong sales withough international supports. 1M sales is relatively easy for household names in Japan
NiziU is the example, their Japanese fanbase is very strong and basically GP knows them because of their survival show was aired on prime time show "Sukkiri". Their debut album exceed 350k+ sales. Predebut single reached a lot of amazing milestones.
Japanese artists can held a large-scale nationwide tour with more than 200k attendance. Either Dome tour or Stadium tour. No international promotion. That's why Kpop artists are expanding their wings to Japan.
Japanese music industry is huge and wide. It is a huge market with wide variety range of genre. Jpop is way more diverse than Kpop. There are rock, heavy metal, pop (idol music and disco dance pop), hip hop, enka, theme music, game music, etc. Each genre has its own fanbase and its huge.
Japanese market is very valuable to every artist that promoting Japan. Strong buying culture.
True, also just want to add something. Idol music is considered just small niche in the jpop music scene. But bcoz most of huge sales come from idol group ppl mistake that jpop only have idol music which is not true at all. 46,48 group and johny idol sell huge amount of physical copy easily 1m every single but jpop not only have idol music. They are very diverse even tho other act not sell much they still have live house. Most other country dont have that anymore. They have live concert, festival, live house every week. The music scene is very lively and small act still can profit from live house even without depending on physical album. Thats why most of their artist have longer lifespan. Coz they can make money doing music their entire live :)
