Usage Notes

Understanding the nuances of Japanese vocabulary numbers requires attention to cultural and grammatical details:

• Two reading systems: Many numbers have both on'yomi (Chinese-derived) and kun'yomi (native Japanese) readings. For example, 四 can be shi or yon, and 七 can be shichi or nana. The reading often depends on what follows the number.
• Avoiding unlucky numbers: The number 4 (shi) sounds like the word for death (死), and 9 (ku) sounds like suffering (苦). For this reason, yon and kyū are often preferred, especially in contexts like hospitals, hotels, and gifts.
• Counters are essential: Japanese uses specific counter words depending on what you're counting. Flat objects use 〜枚 (mai), small animals use 〜匹 (hiki), and people use 〜人 (nin). This is one of the trickiest aspects when you learn Japanese numbers.
• Sound changes: Numbers often undergo sound changes when combined with counters. For example, 一 + 分 becomes ippun (not ichifun), and 六 + 百 becomes roppyaku (not rokuhyaku).
• The 10,000 unit: Japanese counts in units of 10,000 (万) rather than 1,000. So 100,000 is 十万 (jūman - ten ten-thousands), not "one hundred thousand."
• Age expressions: When stating age, 歳 (sai) is added after the number. Some ages have special readings: 20 years old is hatachi (二十歳), not nijussai.
