Why You Might Be Saying 6 and 7 Wrong in Japanese: the Pronunciation Trap
To lock these habits into your speech, study numbers through kana rather than romaji. Romaji allows your brain to retain English phonetic habits. Looking at "roku" invites an American "r"; looking at ろく reminds your tongue to tap the roof of your mouth.
Practice reading basic pairs aloud, paying attention to the pitch drop:
• 6: ろく (roku), Pitch drops after ろ.
• 7 (counting order): しち (shichi), Even, flat pitch.
• 7 (isolated digit / items): なな (nana), Starts high, drops low: NA-na.
• 6 and 7 combined: ろくと、なな (roku to, nana).
Drill alternating between them using standard counters. Practice saying roku-gatsu (June) followed by shichi-gatsu (July). Then switch to counting minutes: roku-fun (6 minutes) and nana-fun (7 minutes). Notice how six triggers a consonant shift in the counter for minutes: 六分 becomes roppun, hardening the sound to facilitate rapid pronunciation.
