I'm not sure if this is just amazon japan or what, but amazon japan will not only show you things that you didn't search for, it will actively rewrite your search query into a query for those things to gaslight you into thinking you typed it in wrong. And if you try to change the text back it replace it again!

On top of all the other insane choices they made, like removing your search category restrictions if it thinks your query was too precise. I'm close to snapping.
