There’s good news and bad news with learning Japanese. The bad news is there’s three alphabets, two with about 50 characters, and a third, Kanji, with 2-3,000. The good news is the first alphabet you learn, Hiragana, has sounds that are repeated for the rest of the alphabets. So once you’ve mastered Hiragana, you should be able to pronounce all Japanese sounds going forward. Not only pronunciation, but Hiragana is also an alphabet that any Japanese word can be written in. So to summarize, once you’ve learned Hiragana, you can speak, write, and read Japanese!
