# How do I choose a hair straightener or curling iron in Japan, and which brands are good?

> As of October 2026, most straighteners and curling irons sold in Japan switch automatically between 100–240V, but a few domestic AC100V models remain, so check the rating label before buying. Choose the type by hairstyle, pick a curling iron by barrel size (32mm for big curls on medium-long hair, 38mm for loose waves on long hair), and a max of 180–200°C is enough for fine hair. Common brands include ReFa, SALONIA, KINUJO, CREATE ION, and Panasonic.

## Types

| Type | Japanese | Best for |
| --- | --- | --- |
| Straightener | ストレートアイロン | Straightening, turning ends under, simple curls |

## Key specs

- **Barrel size (curling iron)**: 26mm for tighter curls, 32mm for big curls on medium-long hair, 38mm for loose waves on long hair.
- **Max temperature**: 180–200°C is enough for fine hair; only coarse or naturally curly hair needs 210–220°C. Higher heat means more damage.
- **Plates (straightener)**: Plate width affects speed; narrow plates are easier for short hair.
- **Voltage**: Models labeled AC100–240V can be used abroad; AC100V models can't be used on 220V power. See [Can I use Japanese appliances back home?](/en/q/japan-appliance-voltage-china/)
- **Plug**: Japanese models use Type A two-flat-pin plugs. Check whether it works in your country in our [compatibility table](/en/tools/compat/).

## Corded or cordless?

Cordless models are handy for touch-ups, but they have built-in lithium batteries and many flight restrictions: under Japanese rules, models whose battery can't be separated are banned from both carry-on and checked baggage. If you fly often, corded or USB-powered models are a better choice. See [Can I take a curling iron on a plane?](/en/q/hair-iron-flight/)

## Common brands

- **ReFa (リファ / MTG)**: Pricier, with strong design and hair-care selling points.
- **SALONIA (サロニア)**: Affordable, many styles.
- **KINUJO (絹女)**: Its straightener is well known among tourists.
- **CREATE ION (クレイツ)**: Many barrel size options for curling irons.
- **Panasonic (パナソニック)**, **TESCOM (テスコム)**, **Koizumi (コイズミ)**: Budget to mid-range.

For voltage, temperature, barrel size, and prices of specific models, see the [hair iron category page](/en/c/hair-iron/).

## Use and care

- Before first use at home, check the rating label voltage again, and use an outlet not shared with other high-power appliances.
- Plates and barrels are coated; keep them away from metal objects and store only after cooling.
- Models with auto shut-off give peace of mind if you forget to turn them off; check the manual to confirm the feature.
- Stores usually let you hold the product, but most won't let you plug it in. You can show the staff: "海外で使えますか？" (Can this be used overseas?).

## Should you buy one in Japan?

Straighteners and curling irons aren't expensive, and popular brands are sold in many countries. Tax-free shopping saves about 9% (from November 1, 2026, it becomes a refund after departure; see the [2026 tax-free guide](/en/q/tax-free-2026/)). The price advantage of buying in Japan should be weighed against prices in your country; when the gap is small, buying at home makes after-sales service easier.
