Peach Aviation Carry-On Rules: Japan's Strictest LCC (2026)

Peach Aviation — branded simply as "Peach" (MM) — is Japan's largest low-cost carrier by fleet size and a wholly owned subsidiary of ANA Holdings, the parent company of All Nippon Airways. Founded in 2011 and operating from its base at Kansai International Airport (KIX) in Osaka, Peach has grown to serve domestic Japanese routes alongside international short-haul routes across Asia.

Peach occupies a distinct space in the Japanese aviation market: a rigorously low-cost carrier with strict operational discipline, efficient turnarounds, and consistent enforcement of its rules — including carry-on baggage. Among Japanese LCCs (which include Jetstar Japan and Spring Japan), Peach is consistently cited as the most diligent about carry-on enforcement.

Understanding Peach's carry-on policy — and the combined weight rule for cabin bag plus personal item — is essential before flying.

Peach Carry-On Allowance at a Glance

Item	Size (cm)	Size (inches)	Weight
Cabin bag	57 × 36 × 23	22.4 × 14.2 × 9.1	↓ Combined
Personal item	40 × 30 × 15	15.7 × 11.8 × 5.9	↓ Combined
Combined total	—	—	7 kg

The critical rule: The 7 kg weight limit applies to the combined weight of your cabin bag AND your personal item together. This is different from airlines that weigh only the main cabin bag. A laptop bag (1.5 kg) plus a carry-on (5 kg) already equals 6.5 kg — leaving just 0.5 kg of margin.

Peach allows a maximum of two carry-on pieces per passenger: one bag (max 57 × 36 × 23 cm) and one personal item (max 40 × 30 × 15 cm). The combined weight of both must not exceed 7 kg.

Why Peach's Combined Weight Rule Matters

Most travelers think of carry-on rules as applying to the main cabin bag only — the personal item (laptop bag, handbag) is typically not weighed separately and not counted against the limit. Peach is different: everything you bring into the cabin counts toward the 7 kg total.

Typical combined weight scenarios:

Scenario 1 — Laptop + small roller:

• Laptop bag with 15" laptop, charger, cables: ~2.5 kg
• Soft cabin bag with 3 days clothing: ~3.5 kg
• Total: 6 kg — within 7 kg limit with careful packing

Scenario 2 — Laptop + standard roller:

• Laptop backpack fully loaded: ~3 kg
• Medium carry-on roller (2.5 kg empty + 3 kg contents): ~5.5 kg
• Total: 8.5 kg — exceeds 7 kg limit significantly

For most Peach travelers, the realistic approach is:

• Laptop bag or small backpack as personal item (~1.5–2 kg)
• Ultralight packable daypack or minimal soft bag as cabin bag (~1.5–3 kg loaded)
• Combined total at or below 7 kg

Travelers who try to carry a laptop bag plus a standard carry-on roller will very likely exceed 7 kg combined.

Size Dimensions

Peach's carry-on size limits are:

Cabin bag:

• 57 cm height (including wheels and handles)
• 36 cm width
• 23 cm depth
• In inches: 22.4 × 14.2 × 9.1

Personal item:

• 40 cm height
• 30 cm width
• 15 cm depth
• In inches: 15.7 × 11.8 × 5.9

The cabin bag dimensions are slightly more generous than some Asian LCCs — the 57 cm height allows for a slightly taller bag than the common 55 cm standard. The 36 cm width and 23 cm depth are standard for Asian budget carriers.

The personal item size (40 × 30 × 15 cm) is small enough to rule out most standard backpacks, which are deeper than 15 cm. A laptop sleeve, thin tote, or purpose-built under-seat bag works best.

Peach's Enforcement: What to Expect

Peach's reputation for strict carry-on enforcement is well-deserved. Based on passenger reports and the airline's own policies:

Bag size gauges at the gate: Peach installs carry-on size gauges (metal frames matching the maximum dimensions) at many of its domestic and international gates. Bags that do not fit inside the gauge must be checked. Staff are trained to direct passengers to test their bags.

Weight checks at check-in: Combined weight is checked at check-in. If you exceed 7 kg, you will be required to pay for checked baggage — at the airport counter rate, which is significantly higher than pre-purchased checked baggage.

Gate enforcement: Staff may conduct random or systematic weight checks at the gate as well. Passengers caught with overweight bags at the gate pay a gate fee that is higher still than the check-in counter fee.

No exceptions for "just a bit over": Peach staff follow policy without the informal latitude that some other carriers give. If you are over, you pay.

Fee Structure for Excess Baggage

Pre-purchasing checked baggage on Peach's website or app is the only cost-effective option if you need to check a bag:

Purchase timing	Relative cost
At booking online	Cheapest
Post-booking via app/web	Moderate
At airport check-in counter	Expensive
At the gate	Most expensive

Prices vary by route (domestic Japan vs. international). Always purchase checked baggage in advance if you know you will need it.

Peach's Network

Peach operates from multiple bases across Japan:

Primary hub: Kansai International Airport (KIX), Osaka

Secondary bases: Tokyo Narita (NRT), Naha (OKA — Okinawa), Sapporo New Chitose (CTS), Fukuoka (FUK)

Domestic Japan: Sapporo, Tokyo, Osaka, Fukuoka, Naha, Amami, Miyako, Ishigaki, Kitakyushu, Nagasaki, Kagoshima

International: Seoul Incheon (ICN), Seoul Gimpo (GMP), Taipei (TPE), Hong Kong (HKG), Manila (MNL), Bangkok (BKK), Singapore (SIN), Kuala Lumpur (KUL), Kaohsiung (KHH), Shanghai (PVG), Osaka–Taipei Taichung

Fleet: Airbus A320 and A320neo aircraft on all routes.

ANA Relationship: What It Does and Doesn't Mean

Peach is 100% owned by ANA Holdings. However:

• ANA Mileage Club miles are NOT earned on Peach flights in most fare classes (some fare families may earn at low rates — check current policy)
• ANA status does not grant carry-on exceptions on Peach flights
• SFC (Super Flyers Card) and ANA elite status are not recognised by Peach for carry-on or boarding priority
• Peach operates entirely independently with its own systems, lounges (none — it's an LCC), and policies

The ANA relationship benefits passengers primarily through connectivity — Peach feeds ANA at Narita and Kansai, and their joint network is complementary.

Restricted Items on Peach

Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT) regulations and international ICAO rules apply:

• Liquids: 100 ml per container in a transparent 1-litre resealable bag; must be in carry-on, removed for screening
• Power banks: Carry-on only; under 100 Wh freely permitted; 100–160 Wh requires airline approval; over 160 Wh prohibited. Japan strictly enforces power bank rules.
• Lithium batteries (spare): Must be in carry-on
• Sharp items: Checked baggage only
• Knives, scissors over 6 cm: Prohibited in cabin

Japanese airport security is thorough and efficient. Liquids rules are enforced consistently.

Practical Tips for Peach Passengers

Pack to the combined 7 kg limit, not just the main bag. Weigh your laptop bag plus your main carry-on together. Most people underestimate how much a loaded laptop bag weighs — typically 2–3 kg.

Choose an ultralight personal item. A thin laptop sleeve, flat tote, or compact under-seat pouch rather than a full backpack keeps the personal item weight low (500 g–1 kg) and leaves more of the 7 kg for your main bag.

Use a packable daypack as your cabin bag. A lightweight packable nylon daypack (400–600 g) maximises the usable weight within 7 kg. Avoid rollers — they eat into weight budget without providing much benefit on short flights.

Pre-purchase checked baggage if in doubt. The cost difference between online and airport purchase is substantial. If there is any possibility you will exceed 7 kg, buy a checked bag at booking.

Test your bag in Peach's size gauge when you arrive. If you have any doubt about your bag's dimensions, try it in the size gauge immediately after arriving at the gate. This gives you time to repack or re-check before the deadline.

Arrive early at KIX and NRT. Peach's check-in lines can be long, particularly at peak domestic travel times (Golden Week, Obon, year-end). Allow extra time at busy Osaka and Tokyo airports.

The Bottom Line

Peach Aviation's carry-on policy — 57 × 36 × 23 cm cabin bag plus 40 × 30 × 15 cm personal item, with a combined weight of 7 kg — is among the most restrictive in Japan's aviation market. The combined weight rule is the key distinction from other airlines: your laptop bag and cabin bag count together. Peach enforces this consistently with size gauges and weight checks. Use ultralight bags, weigh everything combined before leaving home, and pre-purchase any checked baggage at booking to avoid expensive gate fees. Despite the strict rules, Peach offers an efficient, competitively priced service for domestic Japan travel and short-haul Asian routes.
