funny story: this scene was actually improvised. the script originally called for pikachu to roll over onto his side and deliver a line that went “good battling today ash. can we get ihop in the morning?” but during filming, pikachu started thinking about how his real life trainer never hugged him and also will smith’s dad, so he delivered this amazing performance all off the top of his head. the animator was like whoa wtf. what a brilliant moment.
Just to clarify, they are not planning to shut down these websites but have asked them to remove illegal anime/manga content. So no, youtube won’t be shut down. Most of these probably won’t be affected at all since as far as I know Japan doesn’t have any power to do anything other than ask them to take off content.
