Japan Domestic Flight Baggage: JAL, ANA & LCC Rules

Quick Answer: Which Japan Domestic Airline Is Best for Your Bags?

There is no single baggage winner. For a normal suitcase, compare the exact fare result, not only the airline logo. JAL currently gives Economy passengers up to 20 kg of checked baggage free. ANA's domestic Economy allowance can be up to two pieces of 23 kg each, but the allowance depends on the fare. Peach and Jetstar Starter fares can require a paid checked-bag option, while some higher fares or bundles include one.

Cabin baggage is stricter on the low-cost carriers: Peach and Jetstar Starter currently allow two cabin items totaling 7 kg. JAL and ANA allow one carry-on plus one personal item with a 10 kg combined limit, subject to aircraft-size dimensions.

Use this order before paying: identify the operating airline, open the baggage terms for the exact fare, measure the bag including wheels and handles, weigh both cabin items together, and pre-buy any checked allowance online. This guide was checked against official airline pages on August 24, 2026; recheck before purchase.

This table is a booking screen checklist, not a substitute for the confirmation page. Fare names, bundles and fees can change.

JAL Domestic Baggage Rules

JAL permits one carry-on bag and one personal item with a combined maximum weight of 10 kg. On aircraft with 100 or more seats, the carry-on must be within 55×40×25 cm and 115 cm in total dimensions. On aircraft with fewer than 100 seats, the limit falls to 45×35×20 cm and 100 cm in total dimensions.

For checked baggage, JAL currently includes up to 20 kg in Economy. There is no fixed number-of-pieces limit within that weight allowance, but each piece must fit within 50×60×120 cm. Excess weight or size can incur charges and operational limits.

Do not assume a JAL flight number means JAL rules. For a codeshare, the operating carrier's baggage rules apply. Check the airline named beside “operated by” on the booking screen.

ANA Domestic Baggage Rules

ANA also permits one carry-on plus one personal item weighing no more than 10 kg together. For aircraft with 100 or more seats, the main cabin bag must be within 55×40×25 cm and 115 cm total. For smaller aircraft, it must be within 45×35×20 cm and 100 cm total. Wheels and handles count in those measurements.

ANA's current checked-baggage page lists an Economy allowance of up to two pieces at 23 kg per piece, depending on the fare. Each standard piece must stay within 158 cm when length, width and height are added. Premium Class has a larger published allowance, but this guide is designed for ordinary fare comparison.

From July 1, 2026, ANA also publishes a 40×30×20 cm limit for the personal item. That item still sits within the combined cabin-weight allowance. Open the exact booking details because the checked allowance varies by fare.

Peach Baggage Rules

Peach allows two cabin items with a combined weight of 7 kg and combined dimensions of no more than 115 cm for the main bag. The second item does not create another 7 kg allowance.

Peach's current minimum fare requires checked baggage to be added for a fee. Standard and Standard Plus currently include one checked bag. A normal checked unit is 20 kg. With the relevant overweight option, one bag may weigh up to 32 kg. Peach publishes a total operational ceiling of five bags and 100 kg per passenger, with a standard size boundary of 203 cm across three dimensions; larger items need the applicable oversized option and must remain within the airline's maximum.

If your suitcase weighs 18 kg, compare the fare plus one checked bag. If it weighs 24 kg, price the correct overweight option before booking instead of hoping the airport counter will solve it cheaply.

Jetstar Japan Baggage Rules

Jetstar's Starter cabin allowance is two items totaling 7 kg. The main bag must fit within 56×36×23 cm, and the smaller item must fit under the seat. A paid +7 kg cabin option can raise the combined allowance to 14 kg, but a single item may not exceed 10 kg.

Checked baggage is generally not included in a plain Starter fare. It can be added in weight bands, and selected bundles or higher fare types include an allowance. One checked item may not weigh more than 32 kg even when the total purchased allowance is higher.

Jetstar warns that baggage bought or charged at the airport is more expensive than allowance added earlier. The safe move is to weigh the packed bag, open “Manage booking,” and purchase the required allowance before airport check-in.

The Four-Step Baggage Price Test

1. Find the operating airline and exact fare

Write down both. A booking site headline such as “JAL flight” or “Starter” is not enough if a codeshare, bundle or fare family changes the rules.

2. Separate cabin and checked weight

Weigh the main cabin bag and personal item together. Then weigh the checked suitcase separately. Do not move a power bank into checked baggage just to make the cabin bag lighter; use our current power-bank rules for Japan flights before packing batteries.

3. Add baggage to the total trip price

4. Save the final confirmation

Take a screenshot or download the confirmation showing the fare, baggage allowance and operating airline. Recheck after any flight change.

Oversized Bags, Sports Gear and Tight Connections

Airline size rules are not the same as Shinkansen rules. A suitcase accepted by an airline may still need an oversized-baggage seat reservation on some trains. Check our Shinkansen luggage guide before joining a flight and rail itinerary.

For sports gear, musical instruments, strollers or wheelchairs, use the airline's item-specific page and contact it early if the limits are unclear. A general kilograms allowance does not guarantee that an unusually long or fragile item can be accepted on the scheduled aircraft.

Also leave time to check baggage. ANA currently requires domestic checked baggage by 20 minutes before departure at most airports, with a Haneda domestic change to 30 minutes scheduled from September 2026. Other airlines and airports have their own cutoffs. Treat the booking confirmation as the authority.

Plan B When the Bag Does Not Fit

If the allowance makes the flight poor value, do not gamble at the counter. Choose one of these reversible options before travel:

• Add the correct bag or overweight option online.
• Change to a fare that includes the required checked allowance.
• Compare a full-service airline's total price against the LCC total.
• Use a smaller cabin bag and check the suitcase properly.

For Tokyo departures, baggage time can also change which airport transfer is practical. Compare the route and luggage handling in our Narita vs Haneda guide.
