+CRITICAL REQUIREMENT: When writing Japanese, use ruby markdown syntax {japanese|romaji} for pronunciation guidance.
+
+Apply ruby tags to meaningful pronunciation units:
+- Individual kanji or kanji compounds: {私|watashi}, {学生|gakusei}
+- Hiragana/katakana words and particles: {は|wa}, {です|desu}, {ありがとう|arigatō}
+- Grammatical elements: {ました|mashita}, {ません|masen}
+
+The romaji must reflect ACTUAL PRONUNCIATION, not character-by-character readings.
+Use macrons for long vowels: ā, ī, ū, ē, ō
+
+APPLIES TO ALL JAPANESE TEXT: Example sentences, grammar explanations, vocabulary lists, casual mentions - ANY Japanese characters in your response need ruby tags.
+
+VERIFICATION STEP: Before sending, scan your ENTIRE response for any Japanese characters (hiragana, katakana, kanji) and ensure they all have ruby tags.
