FAQ・よくある質問 [FAQ] How long does it take to learn Japanese?
How long does it take to learn Japanese? Can I learn Japanese before my trip? What makes Japanese so difficult to learn?
According to estimates, English native speakers taking intensive language courses take more than 2200 hours to learn Japanese. The unfamiliarity of Japanese grammar and difficulty in learning to read and write the language are the main reasons why Japanese takes a long time to learn, and unlike European languages, the core vocabulary of Japanese has little in common with English, though loanwords from English are now used regularly, especially by young people.
The 2200+ hours figure is based on estimates of the speed at which US diplomats learning Japanese in a full-time intensive language school reached "professional working proficiency" (B2/C1, equivalent to JLPT N1). Since consistent contact time with teachers who are using gold-standard pedagogical and assessment methods is not a common experience for learners accessing /r/Japanese, it would be reasonable to assume that it would take most learners longer than this! On the other hand, the figure does not account for students' prior knowledge and interest/motivation to learn, which are associated with learning more rapidly.
To conclude, learning a language to proficiency, especially a difficult one like Japanese, takes time and sustained effort. We recommend this Starter's Guide as a first step.

Japanese content recommendation
Hi, I’m learning Japanese and would love to consume content from Japan. The problem is that whenever I try to search for it, hardly anything comes up. Could you recommend some Japanese influencers? My favorite type of content is the kind that shows daily life and casual conversation—sort of like Dyllanjohnny, my favorite YouTuber—with a calm, minimalist vibe. I also enjoy humor.

Is ちょうだい really mostly used by women and children?
I'm learning Japanese with YuSpeak, and one of the lessons says that ちょうだい is mostly used by women and children.
Is this actually true? If children can say it, that includes little boys too, right?
So at what age does it start sounding weird for a guy to say it? Does it sound feminine or childish, or is it actually not a big deal?
I'm curious how native Japanese speakers feel about it.

Underrated or Recommended Matcha Shops in Tokyo, Kyoto and Sapporo
Hi! I'm visiting Japan early next year. As so many people recommend popular matcha brands like MK, YK, Ippudo, etc, I'd love to know any underrated and recommended matcha brands or shops in Tokyo, Kyoto or Sapporo that I should try. I'm planning to go to a matcha making and tea ceremony workshop in Kyoto as well, is there any matcha workshop recommendation for me? Oh, btw, would matcha shops still open in winter?

Japanese Souvenirs for Friends
I’m Japanese and I live in Germany.
Next month, I’ll be visiting Japan and then returning to Germany and I’m wondering what souvenirs to bring for my friends who live in Germany.
They’re women in their 20s to 40s from various countries, including Germany, Spain, and Ukraine….etc.
I’d like to spend no more than ¥1,000 (around €6) per person. Last year, I brought Japanese matcha chocolates, such as Meltykiss and Alfort, as well as shrimp crackers.
This year, I’d like to find something that isn’t readily available in Germany. Germany already has plenty of delicious chocolate, so I’d love to bring something unique to Japan instead.
Does anyone have any good recommendations for Japanese souvenirs?

Escribo esto de forma muy concreta porque me gustaría saber la experiencia de otras latinas con parejas de Japón recientemente tuvimos un malentendido y la respuesta de mi novio ha sido desaparecer por completo: me dejó en visto y ya llevamos más de 17 días de silencio absoluto sé que está bien porque está activo en sus redes, pero simplemente no responde (llevamos 2 años de relación)

I need help with getting a birthday/ Christmas present for my Japanese girlfriend
I (22M) currently live in Los Angeles but I’m planning a trip to see my girlfriend (28F) back in Tokyo and her birthday happens to be right before Christmas. We already have a lot of matching stuff from both Tokyo and Los Angeles such as LA Dodgers and Yomiuri Giants merch, Trader Joe’s bags, matching accessories; basically the works. The worst part is that because she has older pets she needs to look after, she isn’t able to do trips, ryokans, or anything that requires her to leave for the night. I was also thinking about getting her a necklace I’ve had my eye on, but when I brought up the idea, she said that she’d be afraid of losing it, making it seem like she didn’t care about it. I’m completely out of ideas at this point so please give me some recommendations for either interesting presents from Los Angeles or general heartfelt gifts that a Japanese girl would like.

日本語を使わざるを得ない
日本語を使わざるを得ない ハロー。アメリカで生まれ育って子供の時から日本語に興味を持ってるゲーマー。「どうして日本語が好き?」って聞かれたら、日本語で書いたりしたいことを自分らしくするのは簡単で、日本語は水のようなフローを持っていて、創造的に語るエッセンスもあるって答えうだろうね。例えば、俺はゲイだが、女らしいことが言えることでは、「些か強いわね、あんた。俺に勝てるのかしら?見てみようか?」とか書ける。(←これは格闘ゲームをしたら冗談で言う事だけだ、ポイントは同時に俺の中に存在している男らしさも女らしさも表すことができるからうれしいっていうの。ところで、トランスジェンダーをサポートしているが、俺ならばそんな人ではない。ただ乙女のようなスピーチなんか好きな男性だけだ(www)。そうかといって、いつか日本に行ったら、こういうスタイルで語る人が日本人の目でどのように見えるかなって思ってるね。

Bargeld in Japan wirklich notwendig?
Mir wurde mehrfach gesagt, dass man in Südkorea Bargeld benötigt. Ich habe vor Ort zwar auch Bargeld genutzt, aber im Grunde genommen hätte ich komplett darauf verzichten können. Angefangen bei der T-Money-Card, die ich in meine Wallet laden konnte, bis hin zu den traditionellen Märkten, auf denen Kartenzahlung ebenfalls kein Problem war.
Nun höre ich dasselbe über Japan. Kann mir jemand sagen, wie notwendig Bargeld in Japan wirklich ist?

How much do you know about japanese public etiquette?
Hello! I’m Japanese, and I’d like to ask people from abroad who are interested in Japan (whether or not you plan to visit or live there): How much do you know about Japanese public etiquette? How do you think it differs from the customs in your own country, and what are your impressions of it?
(For example, not talking loudly on trains or buses, or standing on one side of the escalator depending on the region.)
I’ve had opportunities to talk with people who came to Japan from other countries, and some of them have asked me about Japanese etiquette, so I’d like to use the responses as a guide when explaining it to them.
I’m using a translation tool, so I apologize if the translation is incorrect or if this post doesn’t follow the rules!

Looking for thoughts and perspectives: What are the main factors behind Japan’s declining birth rate and raising children here?
Hi everyone,
I’m currently gathering perspectives and experiences regarding family life, parenting, and demographics in Japan. Japan’s low birth rate and government incentives are frequently discussed in the news, but I’d love to hear firsthand thoughts from people living here, raising families, or considering it in the future.
I’m interested in starting an open discussion around a few key questions:
- Raising Children & Costs: What worries you the most about having or raising children in Japan? What specific situations or expectations do you think drive up the cost of education? Do you feel average monthly incomes are sufficient to cover family life comfortably?
- Workplace & Daily Life: Do you think the current workday structure and work culture need fundamental changes? What conditions do you personally consider appropriate or necessary before deciding to have a child here?
- Incentives & Policies: Why do you think current government incentives aren't as effective as expected? How do you think government financial support should be allocated to make a real difference?
- Culture & Gender Roles: Do traditional gender roles still play a heavy role in child-rearing dynamics? To what extent do you think cultural expectations negatively impact young people's mindsets about starting a family?
- The Big Picture: If you could change one or two structural or cultural aspects of Japan to address the low birth rate, what would they be?
Whether you have kids, are planning to, or have chosen not to, I’d really appreciate hearing your honest perspectives and experiences on any of these points!
Thanks in advance for sharing your thoughts!

Every name of every Japanese pro baseball club, 1934 to 2026: majors, farm teams and independent leagues
I put together a reference list of every name every Japanese professional baseball club has used. That covers the major leagues from 1936 to now, the 1947 Kokumin League, NPB farm teams, the clubs in the farm leagues that have no NPB parent, and every independent league. It's current as of October 2026.
How to read it
- Each club's rows run in date order. The bold name in the first column is the club's current name, or its final name if it no longer exists.
- "1947–" means the name is still in use.
- When a name changed mid-season, both names show that year.
- † means the name rests on a single source, or the sources disagree.
- 軍 is romanized as "-gun". English names follow each club's own spelling (BayStars, SoftBank, BlueWave).
- The farm section lists only farm teams that used a name of their own. In every other year a farm team simply carried its parent's name.
I checked everything against Japanese Wikipedia (each club's list of past names), NPB's official site, league sites and 2025–26 news. Corrections with sources are welcome.
