The Japanese R (ら行): It's Not the English R or L
らりるれろ is the sound that instantly marks a foreign accent, because learners reach for their own language’s R or L and Japanese has neither. The real sound is a quick tap of the tongue, and once you feel it, it’s surprisingly easy.
What ら行 Actually Is
The Japanese ら行 consonant is an alveolar tap: the tongue lightly and quickly taps the ridge just behind your upper teeth, then releases. It is the same motion as the tt in American English “butter” or “water,” or the single r in Spanish “pero.”
It is not the English R (which rounds the lips and pulls the tongue back), and not the English L (which presses and holds the tongue). It sits in between: a single, light flick.
How to Make It
- Say the English word “butter” quickly, American-style: budder. Feel where the tongue taps.
- That tap is your ら行 consonant. Now add a vowel: ら, り, る, れ, ろ.
- Keep your lips relaxed and unrounded. If your lips move, you’re slipping back into the English R.
- Make it light and fast. A long, held sound becomes L; a rounded one becomes R.
The Sound You Already Make
If you speak American English, you produce this tap constantly without noticing. It is the middle consonant in water, butter, and ladder when said at normal speed. Americans do not say those with a full “t” or “d” sound; the tongue taps the ridge once and moves on. That tap is very close to the Japanese ら行 consonant.
So the instruction is not “learn a new sound.” It is: take the consonant you already use in butter, and put it where the R goes. Say butter, isolate that middle tap, then attach あ to it. That is ら.
Speakers of Spanish, Italian, Portuguese, Turkish and Russian have an even shorter route: the single-tap R in Spanish pero (not the rolled RR in perro) is essentially the same articulation.
Mistakes by Language Background
- English speakers: tend to round the lips and retroflex, producing an English R. Relax the lips and shorten the contact to a tap.
- Speakers whose language distinguishes R/L sharply: may force a clear L. Japanese ら is lighter and quicker than an L, so don’t hold it.
- Everyone: over-thinking it. The tap is fast and casual. Speed actually makes it more accurate, not less.
Why Some Positions Are Harder
The tap is easiest between two vowels, which is why あります and ありがとう usually come out fine early on. Both put ら行 in the middle of a word with a vowel on each side, exactly where English speakers already tap.
It gets harder at the start of a word. らいねん and りんご give the tongue no running start, and this is where an English R tends to slip back in. Practise these separately from the mid-word cases rather than assuming one carries over to the other.
The hardest position is a tap next to another consonant sound, as in べんり or しんらい. Here the tongue has to move from a nasal into the tap with no vowel between. Slow the word down, make the tap deliberately, then speed up.

Teacher’s Note
Don’t chase a “perfect” R. Chase a light, quick tap. Record yourself saying ありがとう and compare it to native audio. The single biggest improvement for most learners is simply relaxing the lips and making the contact shorter.
Hear it, then copy it
Nihongo Pass gives you native audio on every word, so you can model your ら行 on the real sound rather than your native language’s R.
