Carry-On Rules Japan: JAL, ANA, Peach and Jetstar

Compare the operating airline before packing for Japan. The allowance depends on the carrier, fare and aircraft; country and airport do not create a universal cabin box.

Japanese Airline Carry-On Policies

ANA and Japan Airlines

ANA and JAL allow one main bag plus one personal item sharing 10 kg in all cabins. Main bag: 55× 40× 25 cm AND 115 cm total, including wheels and handles. On domestic aircraft below 100 seats: 45× 35× 20 cm / 100 cm total. ANA personal item: 40× 30× 20 cm; JAL requires underseat fit without a published numeric box.

Peach Aviation

Peach Aviation includes one cabin bag and one personal item sharing 7 kg. The main bag has a 115 cm total-dimension limit, including protrusions. Weigh both items together, including shopping. Excess must travel as checked baggage; paying a baggage fee does not increase cabin weight. See the Peach guide and check the bag size; the tool does not validate the combined weight.

Jetstar Japan

Jetstar Japan (GK) Starter includes one 56× 36× 23 cm main bag and one small underseat item, sharing 7 kg. The February 2027 JQ change does not apply to GK. Extra-weight options depend on the booking; do not treat the included 7 kg as a paid add-on.

International liquids and checkpoint instructions

Narita’s published international-departure rule covers ordinary liquids in containers of 100 ml or less, in one transparent resealable 1-litre bag per passenger. The container capacity matters even when partly empty. The airport does not publish a general CT-scanner exemption. Do not assume larger containers are permitted because a lane has newer equipment.

Narita describes separate conditions for post-security/duty-free purchases; onward screening and airline restrictions still need checking. Ask about necessary medicines and special articles before travel. Follow staff instructions for presenting liquids, electronics, shoes and outerwear; this guide does not promise a single removal procedure for all lanes at Narita, Haneda and Kansai. Check the actual departure and connecting airports.

Entry, quarantine and medicines

MHLW distinguishes ordinary personal medicine quantities from controlled or prohibited substances and advance approvals. A prescription alone is not import permission. MAFF restrictions depend on product and origin; cooking or vacuum packaging does not exempt regulated meat. Plants can be prohibited or need certification/inspection rather than being banned as one category. Present regulated items at quarantine before customs.

Check Japan Customs for your personal goods, duty-free categories and required declarations. Aggregate means of payment above 1million yen or equivalent are declarable under its listed categories; do not use a fixed dollar amount. The general Japan guide has practical packing and document checks.

Connections and a possible city visit

Use the booking to identify terminals, airports, baggage collection and onward check-in. Narita and Haneda are different airports. Check current transport schedules, entry eligibility and the time required to return through security. A five-hour layover or a train-duration estimate is not a guarantee of a safe city visit.

Before departure, measure the complete bag and account for shopping and combined weight. Use the bag checker alongside the carrier’s current booking conditions; a dimension result alone does not validate weight, customs or security.
