ENTRY & VISA REQUIREMENTS
Passport & Visa
Before traveling to Japan, make sure your passport and visa status meet the entry requirements. Japan has clear but strictly enforced immigration rules, and failing to meet them may result in denied entry.
Passport Validity
Your passport must be valid for the entire duration of your stay in Japan. Japan does not require a minimum number of remaining months on your passport, but it must not expire while you are in the country. If your passport expires during your stay, you may be refused entry.
Visa-Free Entry (Up to 90 Days)
Citizens of many countries can enter Japan without a visa for tourism purposes for up to 90 days. This visa-free stay cannot be extended in most cases, and working or paid activities are strictly prohibited. Always check your country’s eligibility before traveling, as visa rules can change.
>> Check your country details Ministry of Foreign Affairs
Return or Onward Ticket Requirement
Immigration officers often require proof that you will leave Japan within the allowed period. You must have a return ticket to your home country or an onward ticket to another country. Without this, you may be denied boarding by the airline or refused entry at immigration.
Is a return or onward ticket absolutely required?
Yes — officially, a return or onward ticket is required for visa-free entry into Japan. Immigration law states that visitors must prove they will leave Japan within the permitted stay period.
However, not everyone is asked to show it.
Will Immigration Always Check?
No. In practice, Japanese immigration officers do not ask every traveler to show a return or onward ticket. Many travelers pass immigration without being asked, especially if they:
- Come from a low-risk country
- Have a clear travel history
- Stay for a short period
- Have hotel reservations
That said, immigration officers have full authority to request proof at any time.
Airlines May Check Before Immigration
Even if immigration does not ask, airlines often check for a return or onward ticket before boarding. Airlines are responsible for returning passengers who are denied entry, so they may refuse boarding if you cannot prove onward travel.
What Happens If You Don’t Have One?
If asked and you cannot show proof of onward travel:
- You may be denied boarding by the airline
- Or refused entry at Japanese immigration
- In some cases, you may be required to buy a ticket on the spot
Recommended Best Practice
Always have one of the following:
- A return flight ticket
- An onward ticket to another country
- A refundable or changeable flight
- A temporary onward ticket (valid proof, Taiwan, South Korea)
Accommodation Address
Upon arrival, immigration may ask for the address of where you will stay in Japan. This can be a hotel, hostel, Airbnb, or even a friend’s residence. It is recommended to have the accommodation name and address written down or saved on your phone for quick reference.
Travel Tip
Keep a printed or digital copy of your flight details and accommodation confirmation. This helps speed up the immigration process and reduces unnecessary questioning at the airport.
MEDICINE RULES (VERY IMPORTANT)
Japan has some of the strictest medicine and drug regulations in the world. Many medications that are legal or commonly prescribed in other countries are illegal in Japan. Not knowing the rules is not accepted as an excuse, and violations can lead to serious legal consequences.
Prohibited Drugs and Medicines
The following items are strictly prohibited from being brought into Japan, even for personal or medical use:
- Marijuana / cannabis (including medical marijuana and CBD with THC)
- Adderall and other amphetamine-based ADHD medications
- Methamphetamine-related substances
- Any drugs classified as narcotics or stimulants under Japanese law
Possession of these substances can result in arrest, detention, deportation, and long-term travel bans.
Restricted Medicines (Common Mistake)
Some over-the-counter medicines that are widely used abroad are restricted in Japan, especially cold and flu medicines.
Common examples:
- Cold medicine containing pseudoephedrine
- Medicines containing codeine
- Certain allergy and sinus medications
Even small personal amounts may be confiscated, and you may be questioned at the airport.
Prescription Medicines
Prescription medicines are not automatically allowed.
What you should prepare:
- Prescription written in English
- Doctor’s letter explaining:
- Your medical condition
- Medication name and dosage
- That the medicine is for personal use only
Some prescription medicines require official approval before arrival.
Yakkan Shoumei (Import Certificate)
For certain medications, you must apply for a “Yakkan Shoumei” before entering Japan.
Important points:
- Application must be completed before arrival
- Processing may take several days
- Approval must be shown at customs
- Without it, the medicine may be confiscated
Always check if your medication requires this certificate. Amount Limits for Personal Use
Even for allowed medicines:
- Only small quantities for personal use are permitted
- Bringing large amounts may be considered importation and is not allowed
Do not bring extra medicine “just in case.”
At the Airport (Customs Inspection)
Customs officers may:
- Inspect your luggage
- Ask about medicines you are carrying
- Request prescriptions or documents
If you are unsure about a medicine, declare it honestly. Declaring is safer than hiding it.
Best Practice Before Traveling
- Check Japan’s official medicine regulations before your trip
- Do not assume a medicine is allowed because it is legal in your country
- When in doubt, leave it at home or consult official sources
- If necessary, ask your doctor for alternatives that are legal in Japan
Travel Tip
Many common medicines can be purchased safely at Japanese pharmacies after arrival. Pharmacists are helpful, and major cities often have English support.
MONEY IN JAPAN
Cash is Still King
Although Japan is a modern country, cash is still widely used, especially outside major cities. Visitors who rely only on credit cards may face inconvenience.
Why Cash Is Important in Japan
Many small shops, local restaurants, street food stalls, temples, shrines, and rural accommodations do not accept credit or debit cards.
Even in cities, some places accept cards but do not accept foreign-issued cards.
If you go to famous sightseeing spot, you can use card mostly.
When I live in Tokyo, I only carry ¥5,000JPY daily.
Most of Ramen restaurant does not allow to pay by card.
How Much Cash Should You Carry?
It is recommended to carry ¥10,000–¥30,000 in cash at all times. This amount is usually enough for:
- Meals
- Local transportation
- Small purchases
- Emergencies
For longer trips or travel to rural areas, carrying slightly more cash is advisable.
Using Credit Cards
Credit cards are widely accepted at:
- Hotels
- Department stores
- Large chain restaurants and supermarket
- Major tourist attractions
- Convenience store(Seven Eleven, Low-son, Family mart)
However, smaller businesses often prefer cash, and card terminals may not work with overseas cards.
Best ATMs for Foreign Cards
Not all ATMs in Japan accept foreign-issued cards. The most reliable options are:
7-Eleven ATMs
- Available 24 hours
- Located nationwide
- Accept most international Visa, Mastercard, and other cards
Japan Post Bank ATMs
- Widely available across Japan
- Often located in post offices
- Some ATMs have limited operating hours
ATM fees may apply depending on your bank and card issuer.
Payment Tips
- IC cards (Suica / PASMO) can be used for trains, buses, and small purchases
- Always keep some cash even if you have cards
- Keep bills in good condition, as damaged bills may not be accepted
Travel Tip
Exchange rates at Japanese ATMs are usually better than airport currency exchange counters. Withdrawing cash after arrival is often the most cost-effective option.
INTERNET & SIM CARDS
Staying connected in Japan is essential for navigation, translation, train schedules, and emergency information.
However, free public Wi-Fi is limited compared to many other countries.
Free Wi-Fi in Japan
Free Wi-Fi is available in some places such as airports, major train stations, convenience stores, and hotels. However:
- Connections are often slow or unstable
- Registration may be required
- Coverage is limited outside major cities
Do not rely on free Wi-Fi as your main internet source.
Best Options for Travelers
eSim
eSIM is one of the best options for short-term travelers.
- No physical SIM card required
- Easy online setup
- Ideal for solo travelers
- Requires an eSIM-compatible smartphone

Pocket Wi-Fi is recommended for groups or long stays.
- Multiple devices can connect

- Slightly bulky to carry
Physical SIM Cards
Physical SIM cards are also available.
- Easy to buy at airports
- Good for unlocked phones
- You will buy at electric shop(Big camera, Yodobashi camera...)
Where to Buy
The easiest and safest place to buy a SIM card or Pocket Wi-Fi is at the airport after arrival.
Airport counters provide:
- English support
- Clear instructions
- Immediate activation
Buying in the city is possible but may be more difficult due to language barriers and need to go to the city without network.
Japanese Mobile Plans
Local mobile plans such as Rakuten, ahamo, or docomo are designed for residents. They often require:
- Japanese address
- Long-term contracts
- Identity verification
These plans are not suitable for short-term visitors.
Recommended Preparation
- Check if your phone is SIM free
- Confirm eSIM compatibility before traveling
- Compare data plans based on your trip length and data usage
Travel Tip
Set up your internet connection as soon as you arrive at the airport. Having internet access makes transportation and communication much easier from the first moment in Japan.

Understanding how it works will save you time, money, and stress during your trip.

JR Pass Information
TheJapan Rail Pass (JR Pass)
The Japan Rail Pass (JR Pass) is a special train pass created specifically for foreign tourists visiting Japan. It allows unlimited travel on most JR-operated trains for a fixed period of time and can be a good way to save money if used correctly.
Who Can Use the JR Pass
The JR Pass is available only to:
- Foreign visitors entering Japan under a “Temporary Visitor” status
- Short-term tourists staying up to 90 days
Japanese residents and long-term visa holders are not eligible.
Purchase Requirement (Before Arrival)
The JR Pass must be purchased before arriving in Japan.
- It cannot be bought after entering Japan
- Purchase is done online or through authorized agents
- After arrival, you exchange the voucher for the actual pass at JR offices
Without pre-purchase, you cannot use the JR Pass.
Unlimited Travel on JR Trains
The JR Pass allows unlimited rides on:
- JR local, rapid, and limited express trains
- Most JR Shinkansen (bullet trains)
- JR buses and JR ferries (such as the Miyajima ferry)
Not included:

JR Passes are available for:
- 7 days

The pass is valid for consecutive calendar days, not 24-hour periods.
Is the JR Pass Worth It?
The JR Pass is cost-effective only if you travel long distances frequently.
Examples where JR Pass makes sense:
- Tokyo → Kyoto → Osaka → Hiroshima
- Multiple Shinkansen trips within a short time
- Not for backpacker and long term traveler
If you stay in one city or travel short distances, buying individual tickets or using IC cards is usually cheaper.
Seat Reservations
With a JR Pass:
- You can reserve seats for free at JR ticket offices
- You can also use non-reserved cars without booking
During peak seasons, seat reservations are highly recommended.
I recommend you to avoid this term, We also travel in japan.
