I’m going to Japan in a month, been learning 日本語 for years but I’m terrible at recalling vocabulary, need some study tips!

Finally getting the chance to go back to Japan after waiting for three years, I’ll be staying for two months so I’m excited to have some conversations.

I’ve been learning Japanese on and off for around five years but I really struggle to recall vocabulary. I can read both kanas and some kanji, understand the basics of grammar, but whenever I study genki or vocabulary books / lessons, it seems to just dissipate from my memory as soon as it enters.

I would love to hear from anyone who has had the same problem.

Thank you for your time!
