No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyCheck cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.
Editorial signal only. Measure the packed bag and verify the operating carrier's rule.
JAL international guidance: liquid containers up to 100 ml in one transparent resealable bag up to 1 L, with necessary medicine and infant-food exceptions. Confirm transfer screening; this is not a universal domestic limit.
Confirm the infant ticket and checked allowance for the itinerary; no universal extra 10 kg cabin bag or fixed infant fare is inferred.
Own-use collapsible stroller may be checked free under international carriage conditions. Use up to the gate is available only at some airports; confirm at check-in. A cabin stroller replaces the main carry-on bag and must meet aircraft limits.
Own-use infant/child car seat is free under international baggage conditions. Cabin use requires a reserved child seat and prior arrangement; JAL requests application at least 96 hours before departure.

A 55×40×25 cm bag totals 120 cm and therefore fails the 115 cm rule. A 55×40×20 cm bag totals 115 cm. Confirm operating airline and aircraft; cabin storage is not guaranteed.
