Japanese numbers look simple until you try to use them. You start by memorizing one through ten. Easy enough. Then, when counting three dogs, you realize that the word for “three” suddenly changes. That’s when you learn there’s a whole second number system. Then you discover that the way you count flat things differs from the way you count long things.<\/p>\n\n\n\n
This guide covers everything. The two number systems and when each one is used. Counting from one to one million in hiragana and kanji, with pronunciation. The counter system, which is what trips up almost every learner past the beginner stage. And practical ways to actually retain all of this rather than re-Googling it every time you order two beers in Tokyo.<\/p>\n\n\n\n
\n\n\n\n
TL;DR<\/em><\/h2>\n\n\n\n
Japanese has two number systems. The Sino-Japanese system (ichi, ni, san) is used for most counting situations: phone numbers, dates, prices, mathematics. The native Japanese system (hitotsu, futatsu, mittsu) is used when counting general objects up to ten without a specific counter word. Both systems are written using the same kanji (\u4e00, \u4e8c, \u4e09). Beyond the basics, Japanese uses “counters,” small suffix words that attach to numbers depending on what you’re counting. Reading Japanese numbers becomes natural through repeated exposure in real content, not memorisation.<\/p>\n\n\n\n
\n\n\n\n
The Two Japanese Number Systems<\/h2>\n\n\n\n
Most language learners discover with some surprise that Japanese has two parallel ways to count. Unfortunately, they aren’t interchangeable. After memorizing the digits themselves, learners will have to grasp when to use each one. <\/p>\n\n\n\n
System 1: Sino-Japanese Numbers <\/h3>\n\n\n\n
These numbers came from Chinese and are used in almost every counting situation in modern Japanese: prices, phone numbers, years, addresses, times, mathematics, etc.<\/p>\n\n\n\n
Notice that 4, 7, and 9 each have two versions. This isn’t a typo. The “shi” reading for 4 sounds identical to the Japanese word for death (\u6b7b), so “yon” is preferred in many contexts, especially when counting people, hospitals, and anything related to gifts or formal occasions. Similarly, “shichi” can blur with other words, so “nana” is often used for clarity. For 9, “kyuu” is the default; “ku” appears in fixed expressions and time-related vocabulary.<\/p>\n\n\n\n
This kind of variation, where the “right” reading depends on context, is everywhere in Japanese. You will not master it from a chart. You’ll absorb it by hearing native speakers use the numbers in real situations, dozens of times, until the right one starts to come automatically.<\/p>\n\n\n\n
System 2: Native Japanese Numbers <\/h3>\n\n\n\n
These numbers are older and come from the original Japanese language, before Chinese influence. They’re used only for counting general objects from one to ten, when no specific counter applies.<\/p>\n\n\n\n
When would you use this system? Most likely, you’ll use these numbers to count something but don’t know (or don’t want to bother with) the specific counter word. Ordering food at a restaurant is the classic case: “biiru, futatsu” (two beers) is perfectly natural and will be understood everywhere.<\/p>\n\n\n\n
Past ten, the native Japanese system effectively stops. From eleven onward, you use the Sino-Japanese system (ichi, ni, san) regardless of what you’re counting.<\/p>\n\n\n\n
Counting 1 to 100 in Japanese<\/h2>\n\n\n\n
Once you have one through ten in the Sino-Japanese system, building larger numbers becomes mechanical. Japanese counts using a base-ten system, but with a logic that differs from English in one important way: instead of having separate words for “twenty,” “thirty,” and “forty,” Japanese builds them as “two-ten,” “three-ten,” “four-ten.”<\/p>\n\n\n\n
The pattern is consistent: take the digit, add “juu” for the tens place. Twenty-five is “two-ten-five” (ni-juu-go). Forty-three is “four-ten-three” (yon-juu-san). Once you’ve internalized the pattern, you can construct any number from 11 to 99 without memorization.<\/p>\n\n\n\n
Hundreds, Thousands, and Beyond<\/h2>\n\n\n\n
Above one hundred, Japanese continues using the base-ten logic. Note, however, that there is a separate word for ten thousand.<\/p>\n\n\n\n
The sound changes at 300, 600, and 800 happen because Japanese pronunciation rules prefer certain consonant combinations over others. Again, relying on memorization will only lead to frustration. Subtleties and exceptions become intuitive through repeated exposure. <\/p>\n\n\n\n
ichi-oku (a separate word for hundred million)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
Converting between English and Japanese large numbers is a common stumbling block for intermediate learners reading Japanese news or financial articles. Direct translation causes confusion. A salary of “\u4e09\u767e\u4e07\u5186” is not “three thousand yen,” it’s “three million yen” (three hundred ten-thousands of yen). This takes real practice to internalize.<\/p>\n\n\n\n
Counters: The Heart of Japanese Counting<\/h2>\n\n\n\n
When counting most things in Japanese, you don’t just say the number. You attach a small word, called a counter, that classifies what you’re counting. English does this occasionally (“two sheets of paper,” “three loaves of bread”). Japanese is a bit more thorough.<\/p>\n\n\n\n
There are hundreds of counters in Japanese. You don’t need to learn them all. The most common ones cover the vast majority of everyday situations.<\/p>\n\n\n\n
Counter for people: \u4eba (\u306b\u3093 \/ nin)<\/h3>\n\n\n\n
Notice that one and two people use the native Japanese counting roots (hito, futa). From three onward, you switch to the Sino-Japanese numbers with “nin” attached. These two irregulars (hitori, futari) come up often. <\/p>\n\n\n\n
Counter for flat things: \u679a (\u307e\u3044 \/ mai)<\/h3>\n\n\n\n
Used for paper, tickets, plates, shirts, photographs, leaves, anything you’d describe as “a sheet of.”<\/p>\n\n\n\n
\n
\u7d19\u4e00\u679a (kami ichi-mai) = one sheet of paper<\/li>\n\n\n\n
\u5207\u7b26\u4e8c\u679a (kippu ni-mai) = two tickets<\/li>\n\n\n\n
\u30b7\u30e3\u30c4\u4e09\u679a (shatsu san-mai) = three shirts<\/li>\n<\/ul>\n\n\n\n
Counter for long, thin objects: \u672c (\u307b\u3093 \/ hon)<\/h3>\n\n\n\n
Used for bottles, pencils, umbrellas, trees, anything long and cylindrical. This counter is also notorious for its sound changes.<\/p>\n\n\n\n
You’ll hear this counter when ordering beer (biiru ippon), purchasing an umbrella, and in countless other daily situations.<\/p>\n\n\n\n
Counter for small objects: \u500b (\u3053 \/ ko)<\/h3>\n\n\n\n
The universal small-objects counter. Apples, eggs, candies, balls, anything roughly round or compact. This is the “safe” counter when you don’t know the specific one to use, alongside the native Japanese system (hitotsu, futatsu).<\/p>\n\n\n\n
Counter for animals: \u5339 (\u3072\u304d \/ hiki) or \u982d (\u3068\u3046 \/ tou)<\/h3>\n\n\n\n
Small animals (cats, dogs, fish, rabbits) use \u5339. Large animals (cows, horses, elephants) use \u982d. Like other counters, \u5339 has sound changes: ip-piki, ni-hiki, san-biki.<\/p>\n\n\n\n
Counter for machines and vehicles: \u53f0 (\u3060\u3044 \/ dai)<\/h3>\n\n\n\n
Counter for floors of a building: \u968e (\u304b\u3044 \/ kai)<\/h3>\n\n\n\n
Used for floor numbers in buildings. Lives partially in irregularity: ikkai (1F), ni-kai (2F), san-gai (3F, the sound change again), yon-kai, go-kai.<\/p>\n\n\n\n
How to Handle Counters as a Learner<\/h2>\n\n\n\n
Here’s the honest truth about counters: they’re going to take awhile to master. In fact, native speakers themselves get them wrong sometimes. Therefore, there’s broad acceptance of using \u500b (ko) or the native Japanese system (hitotsu, futatsu) as a fallback when you’re unsure.<\/p>\n\n\n\n
You’ll learn counters by hearing them used hundreds of times in context. Knowing that the right counter for “three trains” is less likely to come from memorizing a chart than having heard “san-ryou” (using the train counter \u4e21) enough times. The goal is to use the language intuitively, using your knowledge to produce “what sounds right”. <\/p>\n\n\n\n
This is where reading and listening to real Japanese content in volume becomes essential. Not flashcards. Not memorisation drills. Exposure.<\/p>\n\n\n\n
How to Count in Japanese (and Actually Remember It)<\/h2>\n\n\n\n
The standard advice for Japanese numbers is “memorize the chart.” This is good short-term advice, but it’s not sustainable for fluency. You don’t need to memorize a chart. You need to encounter Japanese numbers in real contexts, repeatedly, until they become automatic.<\/p>\n\n\n\n
