The Three Layers of Japanese Vocabulary

Wago (和語) — Native Japanese

  • Usually written in hiragana or with kun'yomi kanji
  • Core everyday vocabulary: body, nature, emotions, basic actions
  • Examples: 水 (みず, water), 山 (やま, mountain), 食べる (たべる, eat), うれしい (happy)

Kango (漢語) — Sino-Japanese

  • Written in kanji using on'yomi readings
  • ~60% of dictionary vocabulary; academic, formal, technical
  • Examples: 経済 (けいざい, economy), 科学 (かがく, science), 社会 (しゃかい, society)

Gairaigo (外来語) — Foreign Loanwords

  • Written in katakana; mostly from English
  • Technology, food, pop culture, modern lifestyle
  • Examples: テレビ (terebi, TV), パソコン (pasokon, PC), アニメ (anime)

Vocabulary Learning Principles

  1. SRS is non-negotiable: Anki with daily reviews is the most efficient retention method
  2. Frequency-first: Core 2K → Core 6K → sentence mining gives the best coverage
  3. Context over isolation: Example sentences create stronger memories than single-word cards
  4. Kanji + reading together: Always learn the kanji form alongside the reading; don't rely on romaji
  5. Encounter multiple times: New words need ~7–10 exposures in different contexts to fully internalize
