When learning a new language, numbers are often among the first things we encounter.
In the Japanese language, however, understanding numbers goes beyond simple memorization.
The Japanese number system is a complex and fascinating blend of native Japanese readings, Sino-Japanese readings, and various counters that change depending on what you’re counting.
In this comprehensive guide, we’ll explore everything you need to know about numbers in Japanese—from basic counting to using Japanese numerals in different contexts and how numbers intertwine with Japanese culture.
Understanding the Basics: Two Number Systems in Japanese
Two sets of numbers—Sino-Japanese numbers and native Japanese numbers—are at the core of the Japanese number system.
Both play an essential role in Japanese counting and are used in different contexts depending on the situation.
1. The Sino-Japanese Numbers (漢語)
The Sino-Japanese numbers are the most frequently used in daily life in Japan.
They are derived from Chinese numerals and are crucial for counting, telling time, and even in Japanese writing.
Here’s a breakdown of the numbers from 1 to 10 in the Sino-Japanese system:
- Ichi (一)
- Ni (二)
- San (三)
- Shi or Yon (四)
- Go (五)
- Roku (六)
- Shichi or Nana (七)
- Hachi (八)
- Kyū or Ku (九)
- Jū (十)
The Sino-Japanese readings of these numbers are used in various Japanese contexts.
You’ll find them in dates and prices, and when counting higher or larger numbers, For example, July 7th in Japanese is shichi-gatsu nanoka (七月七日), where shichi is the Sino-Japanese reading for 7.
It’s also important to note that some numbers, like 4 and 9, have alternative readings due to their associations with bad luck.
The number 4 (shi) sounds like the word for death (死), while 9 (ku) can sound like the word for suffering (苦).
To avoid these negative connotations, Japanese people often use yon instead of shi and nana instead of shichi.
2. The Native Japanese Numbers (和語)
While Sino-Japanese numbers are prevalent in modern usage, native Japanese numbers are also essential, especially in more traditional or specific contexts.
These numbers are usually used in combination with Japanese counter words to count objects, days of the month, or specific numbers in Japanese culture.
Here are the numbers from 1 to 10 in native Japanese:
- Hitotsu (一つ)
- Futatsu (二つ)
- Mittsu (三つ)
- Yottsu (四つ)
- Itsutsu (五つ)
- Muttsu (六つ)
- Nanatsu (七つ)
- Yattsu (八つ)
- Kokonotsu (九つ)
- Tō (十)
Unlike the Sino-Japanese numbers, the native Japanese numbers are often used without specific counterwords when referring to general quantities or small sets of objects, especially when the exact number isn’t crucial.
For instance, when a child counts toys, they might say, “Mittsu” for three toys, using the native Japanese reading.
Navigating the World of Counters: A Unique Feature of the Japanese Language
One of the most unique and challenging aspects of learning Japanese numbers is using counters. In English, we can say “three dogs” or “two cars.”
However, in Japanese, you must use a specific counterword corresponding to the object you’re counting. This is where the Japanese number system gets more complex.
Common Japanese Counters You Need to Know
Let’s dive into some of the most common Japanese counters you’ll encounter. These counters are used alongside numbers to count various types of objects.
It’s crucial to learn these because using the wrong counter can lead to confusion or miscommunication.
- 人 (nin) – Universal counter for counting people.
- Example: San-nin (三人) means three people.
- 枚 (mai) – Used for flat objects like paper, tickets, or metal sheets.
- Example: Ichimai (一枚) means one sheet of paper.
- 匹 (hiki) – Used for small animals like dogs, cats, or fish.
- Example: Ippiki (一匹) means one small animal.
- 台 (dai) – Used for machines and vehicles.
- Example: Nidai (二台) means two cars.
- 本 (hon) – Used for long, thin objects like bottles, pencils, or trees.
- Example: Ippon (一本) means one bottle.
- 冊 (satsu) – Used for bound objects like books or magazines.
- Example: Issatsu (一冊) means one book.
Counters are vital because they provide context. For example, saying “yon” could mean four of anything, but saying “yon-nin” specifies four people.
Each counterword is tied to a specific category of objects, making it an indispensable part of the Japanese counting system.
Specialized Counters for Specific Objects
In addition to the common counters, the Japanese have specialized counters for particular objects. These counters are used less frequently but are essential in specific fields or traditional settings:
- 杯 (hai) – Used for counting cups or glasses of liquid.
- Example: Ippai (一杯) means one cup or glass.
- 羽 (wa) – Used for counting birds or rabbits.
- Example: Sanba (三羽) means three birds or rabbits.
- 頭 (tō) – Used for counting large animals like cows or elephants.
- Example: Itō (一頭) means one large animal.
- 軒 (ken) – Used for counting houses or buildings.
- Example: Ikken (一軒) means one house.
- 足 (soku) – Used for counting pairs of footwear.
- Example: Issoku (一足) means one pair of shoes.
Learning these specific counters can be challenging, but it’s a great way to deepen your understanding of Japanese culture and language.
The more you engage with the language, the more natural using these counters will become.
Larger Numbers and the Japanese Number System
Once you’re comfortable with counting smaller numbers, it’s time to tackle larger numbers.
The Japanese system for large numbers follows a consistent pattern but differs significantly from the Western system, especially regarding grouping digits.
We typically group numbers in English by thousands (e.g., thousand, million, billion). However, in Japanese, numbers are grouped by ten thousand:
- Thousand = Sen (千)
- Ten thousand = Man (万)
- Hundred thousand = Jūman (十万)
- Million = Hyakuman (百万)
- Ten million = Issenman (一千万)
- Billion = Oku (億)
For example, the number 50,000 is goman (五万), and 100,000 is jūman (十万).
For one million, you would say hyakuman (百万). This system is consistent, and once you understand the base units, you can easily build up to even bigger numbers.
Complex Numbers in Japanese: A Closer Look
When dealing with complex numbers, such as in financial contexts or large measurements, the Japanese system can be more challenging to navigate, especially for beginners. Here’s how to break down and understand more complex numbers:
- 120,000 is juuniman (十二万).
- 3,450,000 is sanbyakuyonjuugoman (三百四十五万).
- 87,000,000 is hachijūnananman (八千七百万).
It’s essential to practice reading and writing these large numbers in Japanese to get comfortable with their unique structure.
Familiarizing yourself with kanji characters for these numbers will also help, as they’re often used in formal or written contexts.
Numbers in Japanese Culture: More Than Just Counting
Numbers are significant in Japanese culture, often imbued with meanings beyond their numeric value.
Understanding these cultural nuances can give you deeper insights into the Japanese way of life and help you avoid social faux pas.
The Concept of Lucky and Unlucky Numbers
In Japanese culture, specific numbers are considered lucky or unlucky, often based on their pronunciation:
- 4 (shi): As mentioned, the pronunciation shi is the same as the word for death (死). This association with bad luck means that the number 4 is often avoided in phone numbers, addresses, and even floors of buildings (similar to how the fourth floor is sometimes skipped in Western hotels due to superstition).
- 9 (ku): Similarly, ku can sound like the word for suffering (苦), making it another unlucky number. Hospitals and clinics, for example, may avoid using the number 9 in room numbers.
- 7 (shichi/nana): Conversely, the number 7 is considered lucky in Japan. It’s associated with good fortune and happiness, reflected in cultural practices like the Tanabata festival, celebrated on July 7th (七夕).
Understanding these associations can be significant in social contexts. For instance, being mindful of these numbers when giving gifts or making arrangements can show cultural sensitivity.
Numbers in Traditional Japanese Practices
Numbers also appear in various traditional practices and beliefs. For example:
- Rokuyo: These are the six traditional days of the Japanese lunar calendar, each associated with different levels of luck. Taian (大安) is the most auspicious day, while Butsumetsu (仏滅) is considered the most unlucky. These days can influence decisions like weddings, funerals, and launching new ventures.
- Omikuji: At Shinto shrines and Buddhist temples, people often draw omikuji (fortune slips) that predict their luck. These fortunes range from Dai-kichi (great luck) to Dai-kyō (great curse), reflecting the importance of numbers in determining one’s fortune.
Numbers in Japanese Writing Systems
In written Japanese, numbers can be expressed using Arabic numerals, kanji characters, or a combination.
The choice of which to use often depends on the document’s context and formality.
Arabic Numerals in Japanese
Arabic numerals are widely used in modern Japanese texts, especially in casual or informal settings.
For example, you’ll often see numbers written as 1, 2, 3, and so on in advertisements, receipts, and digital interfaces.
For example:
- 2024年 (2024 nen) – The year 2024.
Arabic numerals are straightforward and easily understood by anyone, making them a popular choice for everyday use. However, kanji characters are often preferred in more formal or traditional settings.
Kanji Characters for Numbers
Kanji characters for numbers are used in formal documents, literature, and historical texts. These kanji numerals have deep roots in Japanese culture and are often seen in contexts where tradition and formality are emphasized.
For example:
- 一 (ichi) – One
- 二 (ni) – Two
- 三 (san) – Three
- 十 (jū) – Ten
- 百 (hyaku) – Hundred
- 千 (sen) – Thousand
- 万 (man) – Ten thousand
Using kanji characters for numbers in business, contracts, and official documents can convey seriousness and formality.
It’s also common in traditional settings, such as on wedding invitations or in religious texts.
Practical Applications: Using Numbers in Daily Japanese Life
Mastering numbers in Japanese is essential for navigating everyday situations, from shopping to navigating public transport and handling finances. Let’s explore some practical applications:
Shopping and Handling Money
When shopping in Japan, you’ll encounter prices written in both Arabic numerals and kanji. For example, a price tag might say 500円 or 五百円.
Understanding both forms is crucial for daily life, especially in traditional markets where kanji might be more commonly used.
Knowing how to express amounts in Japanese is also essential when discussing money. For example:
- 500 yen is gohyaku en (五百円).
- 1,000 yen is issen en (千円).
- 10,000 yen is ichiman en (一万円).
Converting and understanding these numbers quickly can make shopping and handling transactions much smoother.
Telling Time and Dates
Time and dates in Japanese rely heavily on the Sino-Japanese number system. For instance:
- Hours are expressed with ji (時), so 3 o’clock is sanji (三時).
- Minutes use fun/pun (分), so 10 minutes past 3 is sanji jūppun (三時十分).
Dates follow a similar structure, often mixing Arabic numerals and kanji. For example:
- July 7th (七月七日) is shichi-gatsu nanoka.
Expressing time and dates is a practical skill necessary for everything from setting appointments to planning travel.
