Japan Domestic Flight Baggage Rules for ANA, JAL, and Budget Airlines

Flying domestically in Japan offers an efficient alternative to high-speed rail when traveling between Tokyo and distant destinations like Hokkaido, Fukuoka, Okinawa, or Hiroshima. Domestic air travel operates under distinct regulations compared to international flights, featuring relaxed liquid rules and strict check-in deadlines.

Understanding baggage allowance differences between full-service airlines like ANA and JAL and low-cost carriers like Peach and Jetstar ensures a predictable airport departure.

Full-Service vs Low-Cost Carrier Luggage Allowances

Japan’s domestic market is divided into two primary tiers: Legacy Full-Service Airlines (ANA, JAL) and Low-Cost Carriers (Peach Aviation, Jetstar Japan, Spring Japan, Zipair).

[!WARNING] LCC Gate Scales: Low-cost carriers at Japanese airports (especially Tokyo Narita Terminal 3 and Kansai Airport Terminal 2) employ roving staff with digital hanging scales at the boarding turnstiles. If your combined backpack and duty-free shopping bag exceeds 7.01 kg, you will be forced to check the bag on the spot at premium walk-up gate rates.

Domestic Airport Security Screening and Carry-On Limits

Many international travelers mistakenly assume international security protocols apply to Japanese domestic flights. In reality, Japanese domestic screening is faster, but enforces several unique rules:

A. The Liquid Allowance Exception (No 100ml Rule)

On international flights, liquids are restricted to containers under 100 ml packed in a 1-liter clear plastic zip bag.

On Japanese Domestic Flights:

• Water, tea, sodas, and opened plastic beverage bottles are 100% permitted.
• Thermal flasks and tumblers (e.g., thermos bottles containing hot coffee or water) are allowed.
• Place drink bottles standing upright in the security tray next to your bag. A security officer will place the container onto an automated optical liquid scanner (液体物検査装置). The machine analyzes vapor density through the container wall in 3 seconds. Once cleared with a blue light, it is handed right back to you.
• Alcoholic Beverages — You may bring retail alcoholic beverages with alcohol content up to 70% ABV (up to 5 liters per passenger) in your carry-on or checked baggage.

B. Footwear & Outerwear

• Jackets and heavy coats must be removed and placed in separate plastic bins.
• Boots, ankle shoes, platform sneakers, and thick-soled shoes covering the ankles must be removed and sent through the X-ray machine. Standard low-cut sneakers, loafers, and sandals generally do not require removal unless flagged by the metal detector.

C. Power Banks & Lithium Battery Rules

• Power Banks (Portable Chargers): STRICTLY PROHIBITED in checked cargo luggage. Must remain inside your carry-on luggage.
  • Up to 100 Wh (approx. 27,000 mAh): Unlimited quantities for personal use.
  • Between 100 Wh and 160 Wh: Maximum of 2 units per passenger.
  • Over 160 Wh: Strictly forbidden on commercial aircraft.
• Battery-Powered Heated Hair Curlers — Cordless lithium-ion hair straighteners are prohibited in both carry-on and checked luggage on Japanese flights unless the internal lithium battery cartridge can be physically detached and removed.

The 20-Minute Security Checkpoint Cutoff and Boarding Process

Japan’s domestic airlines operate with clockwork precision. To maintain sub-minute on-time departures, Japanese aviation law strictly mandates time thresholds across every airport:

The Strict 20-Minute Security Rule (保安検査場通過締切)

At T minus 20 minutes before your scheduled flight time, you must tap your QR code boarding pass at the entrance turnstile of the Security Checkpoint (保安検査場).

If you attempt to scan your pass at 19 minutes and 59 seconds, the barrier will light up red, beep an error tone, and staff will inform you that your flight coupon has been automatically cancelled. You will not be permitted through security, even if the plane is still parked at the gate.

Domestic Flight Fare Discounts for International Visitors

Departure Day Airport Security Walkthrough

Before heading to Tokyo Haneda (HND), Tokyo Narita (NRT), Osaka Itami (ITM), or Kansai (KIX), review this checklist:

1. Check your departure terminal before leaving your hotel:
   • ANA / StarFlyer (Haneda Terminal 2)
   • JAL / Skymark (Haneda Terminal 1)
   • Peach / Jetstar / Spring (Narita Terminal 3 or Kansai Terminal 2)
2. Lithium Check — Ensure all power banks, camera batteries, and laptops are inside your personal backpack (carry-on), not inside checked suitcases.
3. Weight Confirmation — If flying Peach or Jetstar, ensure your personal backpack + duty-free souvenir bags weigh under 7.0 kg combined.
