For fluency, you basically need all 2042 jouyji kanji to make life easy. But you would be surprised how well you can get by with only 600-800 kanji. Most kanji you will encounter in everyday use will any
I recommend you either go very far in your kanji Learning, you should aim to learn atleast 700+(JLPT N3) or not bother at all. Learning the most common 100 kanji won’t really do you any good, you will be able to pass JLPT N5 but you will basically have no use for it in real life. You’re better off just focusing on speaking and listening if your only goal is to learn basic japanese to ask for directions while you vacation in Japan.
