Can I enter Japan without a return ticket?

Technically immigration can refuse entry without proof of onward travel, but enforcement varies. Airlines are stricter and may not let you board without a return or onward ticket. Do not risk it. Book a refundable ticket or a cheap onward flight to Korea if you genuinely do not know your return date.

What happens if I overstay my 90 days?

You become an illegal overstayer. When caught or when you try to leave, you face detention, deportation, a ban from re-entering Japan for up to 10 years, and possible prosecution. This is not a minor infraction. Japan tracks overstays and takes them seriously. Do not overstay.

Do I need travel insurance to enter Japan?

No. Japan does not require proof of travel insurance for entry. But you should have it anyway. Medical care in Japan is excellent and expensive. A hospital visit can cost thousands of dollars out of pocket. Buy insurance that covers medical evacuation and hospitalization.

Can I work remotely on a tourist visa?

Gray area but officially no. Japanese immigration defines work as any compensated activity, including remote work for a foreign employer. Enforcement is inconsistent and proving remote work is difficult, but the legal answer is that you need a work visa. Do not tell immigration you are working remotely.

What if my passport expires in 4 months?

You are fine for Japan. Unlike most countries, Japan only requires your passport be valid for the duration of your stay, not 6 months beyond. If you are visiting for 2 weeks and your passport expires in 4 months, you meet the requirement. But renew it anyway if it expires soon. You do not want passport problems while traveling.

Do I need to show proof of funds at immigration?

Rarely asked but possible. Have a credit card with available credit or a bank statement on your phone showing a few thousand dollars. Japan does not publish a specific amount but figure 10,000 yen (65 dollars) per day minimum. If you cannot show you can support yourself, immigration can deny entry.

How to Handle Japan Visa and Entry Requirements for First-Timers

Most Western passport holders get 90 days visa-free in Japan as a temporary visitor. You need a passport valid for your entire stay, a return ticket, and proof of funds. Fill out the Visit Japan Web system before arrival to speed through immigration and customs.

Check if you need a visa. Citizens of 68 countries and regions get visa-free entry for tourism. This includes US, Canada, UK, EU countries, Australia, and New Zealand. You get 90 days (15 days for some countries). If your country is not on the visa exemption list, apply for a Temporary Visitor visa at a Japanese embassy or consulate 3-4 weeks before departure. Bring your passport, application form, photo, itinerary, and bank statements.
Prepare your passport. Your passport must be valid for the entire duration of your stay in Japan. Unlike many countries, Japan does not require 6 months validity beyond your trip. Check that your passport has blank pages for entry and exit stamps. If it expires during your trip or within a few weeks after, renew it now.
Book your return or onward ticket. Immigration may ask for proof of departure. Have a confirmed flight, ferry, or cruise booking out of Japan within your 90-day window. A screenshot of your booking confirmation is sufficient. Do not arrive without this. Open-ended one-way tickets will cause problems at check-in and immigration.
Register with Visit Japan Web. Go to vjw.digital.go.jp and create an account 2 weeks to 6 hours before arrival. Enter your passport details, flight information, and Japan address. Complete the customs declaration. Save the QR codes you receive. At the airport, scan these at the immigration and customs e-gates to skip the paper forms. This system is not mandatory but makes arrival 10 minutes faster.
Prepare proof of funds and accommodation. Japan does not routinely ask for proof of funds or hotel bookings, but immigration officers can request them. Have a credit card or bank statement showing you can support yourself (figure 10,000 yen per day minimum). Have your first night's hotel confirmation accessible on your phone. If staying with friends, have their name and address written in Japanese and English.
Understand the disembarkation card. If you do not use Visit Japan Web, you will fill out a paper disembarkation card on the plane. This asks for your name, passport number, flight, Japan address, and purpose of visit. Write 'tourism' or 'sightseeing' as your purpose. Keep the card with your passport and hand it to the immigration officer. They will staple your landing permission slip into your passport. Do not lose this slip.
Know what you cannot bring in. Japan has strict customs rules. You cannot bring meat products (including beef jerky), fresh fruit, vegetables, or plants. Prescription medications are allowed in reasonable quantities for personal use, but bring the prescription or doctor's letter. Some over-the-counter medications legal elsewhere (like certain cold medicines with pseudoephedrine) are restricted. Check the English customs website or email Tokyo customs before you pack.
Get your re-entry permit if leaving temporarily. If you plan to leave Japan and come back within your 90 days (for example, a side trip to Korea), you need a re-entry permit or you will lose your landing permission. At immigration when you depart, tell the officer you want a Special Re-entry Permit. This is free and allows one re-entry within your original 90-day period. Without this, your landing permission is void when you leave.
