Japan controls its borders carefully, but the process is usually smooth if you know what to expect.
This guide covers everything you need to know about crossing Japan’s borders. You’ll find information on entry requirements, mandatory documents like the Japan CD, and other useful tips.
How Japan’s Border System Works
Japan is an island country. It has no land borders with other nations. All international entries and exits are by:
- Air (airports)
- Sea (seaports and cruise terminals)
Travel within Japan, even between islands like Hokkaidō, Honshū, Shikoku, Kyūshū or Okinawa, is considered domestic, not an international border crossing.
Internal vs. external borders
Here’s an overview of the key differences:
Internal borders (domestic travel)
- Travel by train, bus, domestic flight or ferry inside Japan
- No immigration or customs checks
- You may still pass through normal security checks (e.g., at airports)
External borders (international travel)
- Entering or leaving Japan by international flight or ship
- You must pass through immigration and customs
- Your identity, documents, and luggage may be checked
It’s important to understand these differences before you travel, to avoid unexpected issues.
Entering Japan by Air
Most visitors arrive via one of these airports:
- Narita International Airport (NRT) – near Tokyo
- Haneda Airport (HND) – Tokyo
- Kansai International Airport (KIX) – near Osaka and Kyoto
- Chubu Centrair International Airport (NGO) – Nagoya
- New Chitose Airport (CTS) – Sapporo, Hokkaidō
- Fukuoka Airport (FUK) – Kyūshū
- Naha Airport (OKA) – Okinawa
These airports have dedicated areas for immigration, customs, and sometimes automated gates to speed up entry.
Step-by-step arrival process by air
Follow these steps when you land in Japan:
- Disembark from the aircraft
- Follow signs for Immigration (or “Quarantine / Immigration / Customs”)
- Immigration inspection
- Show passport, arrival card (or Visit Japan Web QR code) and visa if required
- Provide fingerprints and facial photo (biometrics), except for exempt categories such as children under 16 and some diplomats
- Answer simple questions, such as purpose of visit, length of stay, where you will stay in Japan
- Baggage claim to collect any checked luggage
- Customs inspection
- Submit Customs Declaration (paper or digital)
- Bags may be x-rayed or opened
- Officers may ask about items you are carrying or unaccompanied baggage
Remember to check Japan’s rules for declaring items at customs before you depart.
If your flight is late and immigration seems closed
Large international airports in Japan normally keep immigration open to process all arriving international flights, even late-night ones.
If your flight is delayed and you’re worried:
- Stay with airline staff
- Follow staff instructions
- If you miss a connection, talk to:
- Your airline’s transfer desk
- Immigration if you need to re-enter or stay overnight
For airport-specific information, check your destination airport’s official guide.
Entering Japan by Sea
Cruise ships and international ferries usually dock at large ports such as:
- Yokohama (near Tokyo)
- Kobe and Osaka
- Fukuoka / Hakata
- Other ports depending on the cruise route
Some ferries connect Japan with nearby countries like South Korea and China.
Each port has its own cruise terminal and customs/immigration area.
Arrival procedures at seaports
The process is similar to airports:
- Disembark and follow signs to Immigration
- Show your documents
- Provide fingerprints and photo unless exempt
- Proceed to customs
On some cruise ships, part of the immigration or customs process may be done on board before arrival, but you still pass through checks at the port.
Security and baggage checks at sea borders
At ports, Japanese customs can:
- Carry out random inspections
- Look for prohibited or undeclared items
- Inspect:
- Hand luggage
- Checked suitcases
- Special items like instruments or sports equipment
- Any goods you bring off the ship
The rules are the same as at airports.
Domestic Ferries and Internal Travel in Japan
Ferries within Japan (for example between Hokkaidō, Honshū, Shikoku, Kyūshū, and Okinawa) are domestic routes.
There are no immigration or customs controls for domestic travel, but you may pass standard security checks.
Japanese police can ask for ID at any time, so it’s a good idea to keep your documents with you even on domestic trips.
What Security Officers Inspect at Japan’s Borders
When you enter Japan, customs may inspect any items you bring, including:
- Hand luggage and cabin bags
- Checked suitcases
- Strollers, skis, musical instruments
- Boxes or bags you carry by hand
- Items in vehicles (if you arrive by car ferry from another country in the region)
You must declare:
- Large amounts of cash
- Some food, plants, or animal products
- Restricted items such as certain medicines
- High-value goods and commercial items
It’s important to check Japan’s customs and immigration procedures before you arrive.
Documents to Cross Japan’s Borders
The exact documents depend on your nationality and reason for travel, but most travelers should be ready to present:
- Valid passport
- Visa (if required)
- Disembarkation / arrival card
- Customs Declaration form
You can check official visa rules on the Ministry of Foreign Affairs (MOFA) site.
