Does my baby need a passport to go to Japan?

Yes. Every person entering Japan needs their own passport regardless of age. Some countries used to allow children to be listed on a parent's passport, but Japan never accepted this and those systems are now phased out globally. Apply for your infant's passport as soon as you plan the trip—processing takes 4-6 weeks.

Can I work remotely from Japan on a tourist visa waiver?

Legally, no. The 90-day visa waiver is for tourism, visiting family, or short business meetings—not performing work. Many digital nomads do work remotely on tourist stamps, but it's technically a violation. If you're staying long-term or your work is for a Japanese entity, get a proper work visa. For a two-week family vacation where you might check email, immigration won't ask and won't care.

What if we're flying through Japan to another country—do we need documentation?

If you're transiting airside without entering Japan (staying in the international terminal), you don't need a visa. If you're doing a stopover and leaving the airport, you need standard entry documentation. For families with young kids on long layovers, you can enter Japan visa-free for up to 15 days even if your final destination is elsewhere, but you still need valid passports and completed arrival cards.

Do we need an invitation letter from someone in Japan?

Not for tourism under the visa waiver program. If you're applying for an advance visa because you're from a non-waiver country, the consulate may ask for proof of accommodation or a detailed itinerary, but an invitation letter from a Japanese resident is only required for specific visa types (cultural activities, visiting family long-term). Standard tourist visas need hotel bookings and flight confirmations, not invitations.

Can my 17-year-old travel to Japan alone to visit relatives?

Japan has no minimum age for unaccompanied minors entering the country. Immigration will let them in if they have proper documentation. Airlines have their own rules—most require unaccompanied minor service for kids under 12-15, with fees around 150 dollars each way. Your teen should carry a notarized consent letter from both parents, proof of accommodation in Japan, contact information for the relatives they're visiting, and a return ticket. Immigration may ask questions about the purpose of the trip.

How to Handle Visas and Documents When Traveling to Japan with Family

Most Western families visiting Japan for tourism receive a 90-day visa waiver stamp on arrival—no advance visa needed. You'll need valid passports for everyone (including infants), completed customs forms, and proof of onward travel. Children under 20 traveling without both parents may need additional documentation depending on your nationality.

Check passport validity for all family members. Every person needs their own passport, regardless of age. Infants need passports. Japan requires passports valid for the duration of your stay—no six-month rule, but give yourself buffer. Check expiration dates 3 months before booking. Renewing a child's passport takes 4-6 weeks in the US, longer in some countries.
Determine if you need advance visas. Citizens of 68 countries including the US, Canada, UK, Australia, and most EU nations get 90-day visa waivers for tourism. You get stamped at immigration—no paperwork beforehand. If you're staying longer than 90 days, working remotely, or from a country not on the waiver list, apply for a tourist visa at your nearest Japanese consulate 4-6 weeks before travel. Bring everyone's passports, application forms, photos, and travel itinerary.
Prepare parental consent documents if applicable. If children are traveling with only one parent or with grandparents/relatives, some airlines and immigration officers ask for consent letters. Japan doesn't legally require these, but carriers might. Bring a notarized letter from the non-traveling parent(s) stating they consent to the trip. Include child's name, passport number, travel dates, and accompanying adult's name. Keep copies in your carry-on and checked bag.
Fill out arrival documentation on the plane. You'll receive two forms per family: a customs declaration (one per family) and disembarkation cards (one per person including children—parents can fill out for young kids). Fill these out before landing. You need your flight number, accommodation address in Japan, and purpose of visit. Keep a hotel confirmation screenshot handy.
Organize your document stack before landing. Have these ready when you deplane: all family passports, completed disembarkation cards, one customs form, and your return flight confirmation (digital or printed). Put them in one folder or large envelope. Immigration processes families together—you don't split up. The officer will check everyone's passports, stamp them, and wave you through to baggage claim.
Register at your hotel or rental. Japanese law requires all foreign visitors to register their address within 24 hours of arrival. Hotels do this automatically when you check in—they'll scan or photocopy everyone's passports. Vacation rentals must provide registration too, but verify this beforehand. Keep your accommodation's address and phone number written down in case immigration asks.
