**Target keyword:** undercut Japan barber
**Meta description:** Want an undercut at a Japanese barber? Here’s exactly how to ask for it, what mm lengths to request, and what makes Japanese undercuts different.

**Quick answer: Say “undercut please” — Japanese barbers recognize this word. Show a photo, specify your mm length on the sides, and indicate whether you want a hard or tapered disconnect. That’s all you need.**

“I want an undercut… but I don’t know how to ask for it in Japanese.”

Good news: you barely have to.

The undercut is one of the most requested styles worldwide — and Japanese barbers are excellent at it. Here’s exactly how to walk in and get it right.

## ① What Japanese Barbers Call an Undercut

In Japan: **アンダーカット** (*andākatto*).

It’s just the English word in Japanese pronunciation. Every barber will recognize it immediately.

If you want to describe it without the word:
– *”Short on the sides and back”*
– *”Long on top”*
– *”Clear line here”* — draw a horizontal line at your temple with your finger

—

## ② How to Describe Your Undercut in mm

Japanese barbers work in **millimeters**. This is actually great — it removes all the vagueness.

Common undercut combinations:

A classic undercut: **3mm sides, longer on top, clear disconnect line.**

Show your fingers for the number. Hold up 3 fingers and say *”san miri”* — they’ll get it.

—

## ③ Hard Undercut vs. Tapered Undercut

This is the most important decision to communicate before they start.

**Hard undercut** — a visible, sharp line between the short sides and the longer top. Very clean. Very striking.

**Tapered undercut** — the sides gradually blend into the top. More subtle. More versatile.

How to show them which you want:

✔ **For hard:** Draw a horizontal line with your finger at your temple. Say *”here, clean line.”*
✔ **For tapered:** Use a wavy gesture with your hand at the side of your head.

One gesture. That’s all it takes.

## ④ What Makes Japanese Undercuts Different

Japanese barbers tend to:

✔ Cut with **extreme precision** — lines are very clean
✔ Use **clippers and scissors together** for texture on top
✔ Finish with **straight razor work** on the neck and around the ears

The result is often cleaner and more polished than what you’d get in many other countries.

(I’ve watched clients genuinely shocked at how sharp the finish looks — especially the neck line. That’s the straight razor difference.)

## ⑤ Things to Specify — Don’t Leave These to Chance

**How much off the top.**
*”Just the ends, keep the length”* or *”Take off about 2cm.”* “Just a trim” is too vague.

**Texture.**
Some Japanese barbers add thinning by default. If you don’t want it: *”No thinning please.”*

**Neckline.**
Tapered or square? *”Square back”* is understood almost everywhere.

**Parting direction.**
If you wear a specific part, show the barber in the mirror before they start. Not after.

## ⑥ Bringing a Photo

A photo is your best tool. Save it to your camera roll — no internet required.

Show it before you sit down. Most barbers will study it carefully and confirm they can replicate it.

Choose a photo where:

✔ Lighting is clear
✔ The style matches your hair type
✔ You’re happy with every single detail — they’ll aim to match it closely

—

## ⑦ What It Will Cost

An undercut at a Japanese barber: **¥3,500–¥6,000**, including shave and service.

Higher-end shops may charge more — but you can usually check their portfolio work on Instagram beforehand.

—

## Summary: What to Say

Walk in. Show your photo. Say:

> *”Undercut please. Short on sides — [hold up fingers for mm]. Long on top. Like this photo.”*

That’s genuinely enough to get started.

Your barber will ask clarifying questions as they go — with gestures, with the mirror, or with a nod.

Trust them. They’ve done this thousands of times.
