Should I book flights for the whole family on one reservation?

Yes. Keeping the entire family on a single PNR (Passenger Name Record) makes it significantly easier for the airline to move everyone if a flight is canceled or delayed.

Is it better to fly into Osaka or Tokyo for a family trip?

Tokyo is better for a first trip due to flight frequency and transport options, but if you want to focus on Kyoto, check for direct flights into Kansai International (KIX) to save a 3-hour train ride.

How to Book Family Flights to Japan

Book your Japan flights exactly 6 to 8 months in advance to secure group seating without paying premium last-minute prices. Use Google Flights to track price drops for your specific dates, and prioritize direct flights to Tokyo (NRT or HND) to avoid the stress of connecting with children.

Set up a Google Flights alert. Enter your departure city and Tokyo (all airports) as the destination. Select 'Non-stop only' and toggle on 'Track prices' for your specific dates. You will get an email notification the moment the fare drops.
Check the seat map before buying. Before you pay, use a site like SeatGuru to verify the aircraft layout. For a family, ensure there are blocks of at least 3-4 seats together. If the flight is already nearly full, avoid it, as you likely won't be able to sit as a group.
Select the right arrival airport. Haneda (HND) is closer to central Tokyo (20-30 minutes by train/taxi), while Narita (NRT) is about 60-90 minutes away. If you have young kids, the extra cost for a Haneda arrival is worth the time saved.
Verify airline child policies. Check the airline's website specifically for 'Child Fare' rules. Some carriers offer a small discount for children under 12, but many international flights treat them as adults. Ensure you have the kids' passport numbers ready, as you usually cannot book international tickets without them.
