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?
• Plug: Japanese models use Type A two-flat-pin plugs. Check whether it works in your country in our compatibility table.

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?

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.

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). 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.
