すもももももももものうち (Sumomo mo momo mo momo no uchi)
すもももももももものうち (Sumomo mo momo mo momo no uchi)
Both plums and peaches are types of peach
Why Is It Hard?
This sentence is almost entirely built from mo and momo sounds. The word for plum (sumomo), the word for peach (momo), and the particle mo (also) all blur together at speed. It is grammatically correct Japanese but sounds like a sound machine rather than a sentence.
History
Sumomo mo momo mo is frequently cited as the ultimate Japanese tongue twister. It appears in dictionaries of hayakuchi kotoba and is used as a linguistics example to show how Japanese particle grammar can create unintentional phonetic loops. Children love it because it sounds almost nonsensical even though it makes perfect sense.
Tips for Saying It
- Write it out: identify each word boundary before speaking.
- Slow practice first – sumomo / mo / momo / mo / momo / no / uchi.
- Clap on every mo to keep track of where you are.

Why This Tongue Twister Is So Hard
Sumomo mo Momo mo Momo no uchi (plums and peaches are both in the peach family) is famous for containing almost only the syllables “mo,” “mo,” “mo.” The full sentence uses the particle “mo” (also/and) five times alongside the words sumomo (plum) and momo (peach). Every syllable sounds nearly identical.
This makes it one of the most disorienting tongue twisters in Japanese because there is no clear landmark to orient yourself. You are essentially chanting “mo” with slight variations while trying to preserve the grammatical meaning. Speed eliminates any distinction between the syllables.
The Grammatical Trick
The sentence has actual meaning: “Both plums (sumomo) and peaches (momo) are types of peaches.” The particle “mo” means “also” or “and,” and it appears twice – once after sumomo and once after momo. The phrase “momo no uchi” means “within the peach family.” So the sentence is a botanical statement wrapped in a phonetic torture device.
Practice Tips
- Write it out and count the “mo” syllables before speaking (there are 5)
- Mark the word boundaries: SU-mo-mo / MO / mo-mo / MO / mo-mo / NO / U-chi
- Say it at half speed until you can feel where each word ends
- This one benefits from muscle memory – repeat 20+ times per session
Difficulty Rating
Difficulty: 5/5. Considered the hardest Japanese tongue twister for non-native speakers because every syllable sounds the same. Even many native Japanese speakers lose their place mid-sentence. It appears in Japanese difficulty rankings as a top-tier challenge.
