A vast majority of Japanese Gura fans don't actually enjoy Gura's content, they just like her character design because it's cute and marketable as fuck which is a very, very big thing in Japan and is the reason why Hello Kitty is the second highest revenue generating franchise in human history just behind Pokemon.
She doesn't need to learn Japanese to have her posters plastered all over Japan or for them to buy her figures. She most likely realized this after seeing the breakdown of her revenue and no longer cares enough to put in the time required to learn a second language. JP Holo will continue to obsess over her regardless just because she's small and cute and has a good design and Japanese fans will continue to throw money at her for the same reason.
