Big Publisher Kadokawa (responsible for 99% of all popular LNs) made a statement regarding the revenue made by publishing なろう系 (Narou) Web novels recently. 小説家になろう is a platform Japanese Amateur writers use to publish their own webnovels for people to read without too much commitment. Famous titles such as Tensura, Overlord, Kagejitsu, Mushoku Tensei, Re:Zero all started from なろう。 Most Isekai LN/Anime come from this site as the popular titles get picked up by big publishers and animation studios. Kadokawa claimed that they first initially decided to change directions to publish more なろう系 webnovels because they sold extremely well and rose quickly to popularity. That being said, they're now seeing a lack of decent hit pieces because "the quality" of the works published are simply not good enough. They seem to be considering a change in direction within their company's inner workings and a lot of Japanese fans are speculating that the "great なろう boom" is about to end soon, meaning there could start to be a lack of Isekai LN/Animes in general.
