Your flight has landed. You collect your passport, follow the signs, and suddenly face unfamiliar procedures. CIQ in Japan covers three separate checks: quarantine, immigration and customs. Knowing what each one does helps you prepare before departure and avoid problems with items in your luggage.
The Problem Every Visitor Hits
The aircraft door opens. Everyone begins reaching for their bags, checking their phones and preparing to leave. You may have spent months planning your trip, yet the first hour in Japan can still feel uncertain.
CIQ stands for Customs, Immigration and Quarantine. These checks serve different purposes. Immigration examines whether you may enter Japan. Quarantine checks certain health risks, including diseases carried by animals and plants. Customs checks goods entering the country, including items that must be declared or cannot legally be imported.
The order matters. After leaving the aircraft, follow airport signs and staff instructions. Depending on your arrival airport and circumstances, you may encounter quarantine guidance or inspections, followed by immigration. You then collect checked baggage and proceed through customs. The precise route varies by airport.
The Japanese government has also identified entry procedures as a real source of difficulty for international visitors. In its FY2025 visitor-environment survey, 10.3% of respondents reported problems with immigration procedures. See the Japan Tourism Agency’s survey announcement.
The practical lesson is simple: do not leave every decision until you reach the airport. A few checks at home can prevent confusion when you are tired after a long flight.
Before departure: save your first accommodation’s address, check your entry requirements and review every food item packed in your luggage.
Why This Happens
The difficulty is not simply the number of queues. Each procedure asks a different question, and a mistake in one area cannot necessarily be solved at another counter.
Immigration is about permission to land. According to the Immigration Services Agency of Japan, foreign nationals generally undergo landing examination and must meet the applicable entry conditions. Your passport, visa requirements and stated purpose of travel matter. Visa exemption depends on your nationality and circumstances; it is not a universal rule for every visitor.
Quarantine addresses a different risk. Japan protects people, livestock and agriculture from diseases and pests that can cross borders. A packaged snack containing meat, for example, may raise a different issue from a personal item such as a jacket. Fresh fruit can also be subject to plant quarantine restrictions.
These rules have a direct connection to everyday life in Japan. Farmers depend on healthy crops, and livestock diseases can affect entire agricultural communities. Restrictions on imported meat and plants are therefore not just airport formalities. They help protect the food systems on which local communities depend.
Customs focuses on goods, including whether you must declare belongings, pay applicable duties or comply with restrictions. It is separate from immigration, even when digital systems help travellers complete parts of both procedures together.
That distinction explains a common source of confusion: passing immigration does not mean every item in your suitcase is permitted. Each check has its own purpose.
Before packing: check immigration requirements, animal and plant quarantine rules, and customs declarations separately.
Tip 1 — The One That Matters Most
The most useful preparation is to check what you intend to bring into Japan, rather than relying on what seems harmless.
Step 1: Review food, plants and animal products
Japan generally prohibits bringing in many meat products and restricts many fruits and vegetables. Examples include beef or pork jerky, ham, sausages, meat buns and sandwiches containing meat. Vacuum packaging, cooking, gift packaging or buying an item at an airport duty-free shop does not automatically make it admissible.
The Animal Quarantine Service explains the restrictions on animal products. The Plant Protection Station provides guidance on plants and plant products.
Do not assume a food is permitted simply because it is commercially packaged. Requirements can depend on the product and its origin. Some items may be permitted under specific conditions, but you should verify those conditions before travelling.
Step 2: Check medicines, valuables and other restricted goods
Medicines, controlled substances, weapons, counterfeit goods and certain other items may be subject to restrictions or legal requirements. Rules differ by category, and a prescription or permission from another country does not automatically establish that an item may be brought into Japan.
Check the relevant Japanese authority’s current guidance for your exact product. If you cannot establish that an item is permitted, seek clarification before packing it.
Step 3: Decide what to declare
Japan Customs requires arriving passengers to declare their belongings. The green channel is for passengers with no goods requiring declaration and no prohibited or restricted goods. The red channel is for other passengers.
Read the official passenger clearance guidance before deciding which channel applies to you. If you are unsure, ask a customs officer rather than choosing the green channel simply because you believe your belongings are ordinary personal items.
A useful distinction is that declaring an item and being allowed to import it are not the same thing. An item can require inspection, documentation or permission, and some items cannot be brought in at all.

Before you zip your suitcase: search the official Japanese guidance for each food, plant, medicine or other item that could be restricted.
Tip 2 — Before You Go
Prepare the information you will need to answer questions and complete declarations. You do not need to memorise every rule. You need to know where to find reliable answers.
Start with your passport and visa requirements. Check the current rules for your nationality, purpose of travel and planned stay through the Immigration Services Agency and the appropriate official visa guidance.
Next, consider using Visit Japan Web, the Japanese government’s online service for entry procedures and customs declarations. The Digital Agency’s official guide explains how to register your details, enter your travel information and complete the relevant procedures.
Once the required information is registered, the service provides a two-dimensional code, commonly called a QR code, for the applicable procedures. Follow the current instructions displayed by the service and at your arrival airport.
Visit Japan Web can reduce the amount of information you need to enter manually at the airport. However, it does not replace every inspection or guarantee immediate passage. Customs officers may still inspect baggage, and immigration officers retain responsibility for entry decisions.
Keep your passport accessible, and save the address of your first accommodation in a form you can retrieve without an internet connection. A screenshot or written note can help if airport Wi-Fi is unreliable.
You should also know what is in your checked baggage. If someone else packed a gift or you are carrying food for a friend, ask what it contains. You remain responsible for understanding and declaring the items you carry.
Japanese public services increasingly use digital tools, but physical signs, officers and paper procedures remain relevant. Preparing digitally is useful; knowing how to ask for assistance is equally valuable.
The day before flying: complete the available online procedures, save your QR code, confirm your accommodation address and check your packed items once more.
Tip 3 — On the Ground
After landing, follow the airport signs instead of copying the person walking ahead of you. Passengers on the same flight may have different entry requirements, so their route may not be yours.
First, follow any applicable quarantine instructions. If you are carrying animal or plant products, check the relevant rules and use the designated inspection process where required. Do not conceal an item because you are unsure whether it is permitted.
Next, follow the signs for foreign nationals and proceed through immigration as directed. Keep your passport ready. Officers may ask about the purpose of your visit, your intended stay or where you will be staying. Answer accurately and consistently with your travel plans.
Some immigration procedures use electronic systems, but do not assume that every arriving foreign visitor can use a facial-recognition gate. Available equipment and eligibility vary by procedure and airport. Follow the instructions for your passenger category.
After immigration, collect your checked baggage and proceed to customs. Use the electronic declaration process if available and applicable, or complete the paper declaration procedure. Japan Customs continues to provide paper forms as an alternative to electronic declarations.
At customs, select the appropriate channel. If you have goods to declare, or are uncertain whether your belongings require declaration, ask an officer. Do not assume that an electronic QR code means you can skip all checks.
If you need help, these phrases can make the next step easier:
- Sumimasen. — Excuse me.
- Eigo no annai wa arimasu ka? — Is there information in English?
- Kore wa shinkoku ga hitsuyou desu ka? — Do I need to declare this?
- Kore o motte haitte mo ii desu ka? — May I bring this into Japan?
- Nihongo ga wakarimasen. — I do not understand Japanese.
You do not need perfect Japanese to ask for help. Clear questions and honest answers are more useful than guessing at a rule you do not understand.
At the airport: keep your passport ready, follow the signs for your category and ask an officer whenever a declaration or restriction is unclear.
Common Mistakes to Avoid
1. Assuming packaged food is always allowed
A sealed packet of jerky may look like an ordinary souvenir, but processing and packaging do not automatically remove animal quarantine restrictions. The same caution applies to fresh fruit and certain plant products.
Japan’s restrictions aim to prevent pests and animal diseases from crossing borders. These risks can affect farmers and agricultural communities long after a visitor has left the airport.
Avoid this mistake: check the product and its origin against official quarantine guidance before packing it. If you discover a prohibited item at the airport, follow staff instructions and use the designated disposal process where available.
2. Treating a completed QR code as permission to enter
Visit Japan Web helps with information submission. It does not guarantee landing permission or exempt you from customs inspection.
Immigration officers assess entry requirements, while customs officers examine declarations and goods. These responsibilities remain separate even when electronic systems bring parts of the process together.
Avoid this mistake: complete the online procedures accurately, keep your passport ready and follow the officer’s instructions.
3. Choosing the green customs channel without checking
Travellers sometimes think the green channel is appropriate whenever they are not carrying commercial goods. That is not the rule. The relevant question is whether you have goods requiring declaration or goods prohibited or restricted from import.
Personal gifts and items bought overseas can still fall under customs or quarantine requirements. When in doubt, ask an officer before choosing a channel.
Avoid this mistake: review your belongings, check the current declaration rules and do not hide or discard an item simply to avoid a question.

Before entering the customs area: confirm which channel applies to your belongings, and ask staff if you cannot decide confidently.

Closing
Japan’s entry procedures become easier to navigate when you understand why each check exists. Immigration concerns permission to land; quarantine protects against biological risks; customs checks goods entering the country.
Before your trip, take ten minutes to review your belongings and complete any relevant online procedures. That small preparation can help you spend less time guessing at the airport and more time enjoying your first walk through Japan.
