Learning Numbers in Japanese
What makes Japanese numbers challenging
Two parallel number systems (Sino-Japanese and native Japanese) that must be used in the right contexts. Counter words (classifiers) are mandatory — different objects require different counters based on shape, size, and category. The digits 4 and 7 each have two readings (shi/yon, shichi/nana) with strong cultural preferences: shi (4) sounds like death and is avoided. Large numbers are grouped by 10,000 (man) not 1,000, requiring mental re-grouping for English speakers. Sound changes (rendaku) alter some numbers when combined with counters.
Tips for learning Japanese numbers
Learn Sino-Japanese numbers first — they cover most situations including phone numbers, prices, dates, and math. Always use yon (not shi) for 4 and nana (not shichi) for 7 in everyday counting. Master the man (10,000) unit early for large numbers. Start with the general-purpose counter -tsu for objects before learning specific counters. Practice with Japanese prices (yen amounts are always large numbers since there are no decimal coins) for excellent real-world number comprehension.
