Silly bit of insight. A Declan shower thought in X form, if you will.
In light of the drastic increase in timeline cross-pollination on X between Japan and the US, I've seen a considerable uptick in people on our side of things interested in learning Japanese. I think that's awesome. But I also want to explain some things as a student of the language that those eager to learn should know before diving in.
This is not Spanish, or French, or Italian. This is not a language that you can reach Native speaker status with 800 hours of hard work and immersion. This is 2200 hours, minimum, for conversational fluency.
It is an agglutinative language. You will be learning words that feel exhaustively long just to convey without risk of confusion the very circumstances in which that thing you're describing was in a state of being. Tenses, positive or negative connotation, individual or group, all very sticky. That's what agglutinative means, "to stick on". Think old school German, on steroids.
It also has, at minimum, eight distinct prominent sociolinguistic factors that determine manner of speech. Things such as age disparity, familiarity, direction of benefit, weight of conversation, and position within social hierarchies both explicitly defined and unspoken, are all relevant.
It is also the single most complex writing system in the world, and it's not even close. Hangul can be learned in an afternoon. Hiragana, katakana, and Kanji, and the circumstances in which each are used, is 500 hours on its own.
Now for the good news. It's a hard language, perhaps the most difficult language to reach real fluency on a level of deep cultural understanding, for a native English speaker. I would say it's a toss up between Japanese and Cantonese. But if you can learn Japanese you can learn any language. It unlocks core linguistic reasoning and understanding skills for almost every other language on Earth.
There are wonderful tools. Anki and Genki are great learning tools. There are entire series on YouTube dedicated to teaching the language and its nuances in a way that is engaging and fun, often centered around topics to which you may be naturally drawn.
Believe it or not, the tool with the single strongest potential is an LLM such as Grok or Gemini, so long as you set up your prompts correctly. These tools can have you upload audio and grade your speaking, comparing it to native speakers. They will give you multiple ways to say the same thing based on likely scenarios. They will test you the right way, with staggered recall to ensure the most efficient transfer from short-term memorization, to real long-term recall.
Duolingo is... a 2 out of 5. That's being generous. Rosetta Stone is worse. The "Pimsleur Approach" is not recommended for any language in my opinion, let alone Japanese.
Final notes: don't give up. You'll have bad days. Not every word, phrase, and concept will come easily. The stroke order of some Kanji will make your hair thin early. My recommendation? Go old school. This is X. The best pen pal system in the world. Buddy up with a Japanese student studying English. Talk to each other about shared hobbies. Make it part of your routine, and ditch the crutch of romaji as soon as you're comfortable.
Good luck guys! Let's all continue to share this re-emboldened allyship with one another. God Bless.
