Seattle to Tokyo
Seattle-Tacoma (SEA) has nonstop flights to both of Tokyo's airports. Haneda is close to the city center and is the hub for domestic flights, including many to Kumamoto. Narita is farther out and is served by Alaska Airlines, Seattle's hometown airline.
| Arrives at | Airlines from SEA | Frequency | Flight time |
|---|---|---|---|
| Haneda | ANA, Delta | About 2 nonstops a day in total | About 10.5–11.5 hrs |
| Narita | Alaska Airlines, Japan Airlines (JAL) | Daily service | About 10.5–11.5 hrs |
From Portland, Spokane, Anchorage, Boise and other Pacific Northwest cities, connect in Seattle. You cross the International Date Line, so you land in Japan the day after you leave, usually in the afternoon. Schedules change by season, so check with the airlines.
From the airport into Tokyo
Haneda
The Keikyu Line or Tokyo Monorail reaches central Tokyo in about 15–30 minutes, and Shinagawa, a Shinkansen station, is about 15 minutes away. Stark House Tokyo Haneda is a short ride from the airport, which makes it an easy first and last stop after a long flight.

Seattle to Osaka
There are no nonstop flights from Seattle to Osaka, but one connection gets you there. Osaka's international gateway is Kansai International Airport (KIX), built on an island in Osaka Bay. It's the best arrival point for Osaka, Kyoto and Nara.
| Option | How it works | Good to know |
|---|---|---|
| Via Tokyo | Fly nonstop to Haneda, then take a domestic flight to Osaka, or take the Shinkansen from Shinagawa to Shin-Osaka (about 2.5 hrs). | The most flight choices, and you can add a few days in Tokyo |
| Via Seoul or Taipei | Fly from Seattle to Seoul or Taipei, then take one of the many short flights to Kansai. | Lands you directly at Kansai, and a stopover adds an extra destination |
| Via the West Coast | Connect in Los Angeles or San Francisco to a nonstop flight to Kansai. | Worth comparing fares and times |

JR Haruka to Shin-Osaka
The limited express Haruka runs directly to Shin-Osaka in about 50 minutes and continues to Kyoto. Stark House Osaka Higashimikuni is one subway stop from Shin-Osaka, so it's easy to reach on arrival and a good base for trips across Kansai.
Nankai to Namba
The Nankai Line, including the rapi:t limited express, runs to Namba in southern Osaka in about 35–45 minutes. Good if you're heading to Dotonbori and the Minami area.

Seattle to Kumamoto: four ways to get there
There are no nonstop flights from Seattle to Kumamoto, but one connection gets you there. Kumamoto's airport is officially called Aso Kumamoto Airport (code KMJ). It sits east of the city, on the road towards Aso. These are the most practical routes from Seattle:
| Route | How it works | Connection | Best for |
|---|---|---|---|
| Via Tokyo Haneda or Narita | Nonstop from Seattle to Haneda with ANA or Delta, then a domestic flight to Kumamoto from the same airport. | Haneda–Kumamoto: many flights a day with JAL and ANA, about 1 hr 45 min. Narita–Kumamoto: Jetstar Japan, about 2 hrs. | Most travelers. Easiest, with the most flight choices |
| Via Osaka Kansai | Connect to Kansai via Seoul, Taipei or the West Coast, then take the Shinkansen or a domestic flight. | Shinkansen from Shin-Osaka to Kumamoto: about 3 hrs, no changes on the faster services. Flights also run from Osaka Itami. | Combining Kyoto or Osaka with Kyushu |
| Via Seoul or Taipei | Fly from Seattle to Seoul (Incheon) or Taipei (Taoyuan), then take a direct international flight to Kumamoto. | Seoul–Kumamoto: Korean Air and Trinity Airlines, daily, about 1 hr 30 min. Taipei–Kumamoto: STARLUX and China Airlines, about 2 hrs. | Flying straight into Kumamoto, or adding a stopover |
| Via Fukuoka | Connect through an Asian hub to Fukuoka, then take the Kyushu Shinkansen. | Fukuoka Airport to Hakata Station by subway: about 5 min. Hakata to Kumamoto by Shinkansen: about 35–40 min. | Pairing Fukuoka with Kumamoto on one trip |
Overview as of October 2026. Flight days, times and fares change by season. Check the airlines' websites for current schedules.
Tips for choosing your route
Book the domestic leg on the same ticket
ANA sells its own domestic flights, and Alaska Airlines partners with JAL, so you can usually add the Kumamoto flight to the same booking. Your bags are checked through, and the airline will rebook you if the first flight is delayed.
Haneda is easier than Narita
Most Kumamoto flights leave from Haneda. If you land at Narita, either connect to Jetstar's Narita–Kumamoto flight or allow time to cross Tokyo, which takes about 1 to 1.5 hours.
Give yourself a buffer
Allow at least 2 to 3 hours for an international-to-domestic connection in Japan. You clear immigration and customs at your first airport, collect your bags, and usually change terminals.
Plan a night in Tokyo
Most flights from Seattle land in the afternoon, the day after you leave. Many travelers spend the first night near Haneda and fly to Kumamoto the next morning, fresh for the drive to Aso.
From Kumamoto Airport to your destination
There's no train line into the airport, so most visitors use the bus, the free shuttle or a rental car.
| Option | Goes to | Time and cost | Good to know |
|---|---|---|---|
| Airport limousine bus | Kumamoto city center and Kumamoto Station | About 50–60 min. Around ¥840 to the Kumamoto Castle area | The most popular option. Runs frequently and accepts IC transit cards |
| Free airport shuttle Airport Liner | JR Higo-Ozu Station | About 15 min. Free | Change to the JR Hohi Line for the city or for Aso |
| Rental car | Aso, Amakusa, Kurokawa Onsen and other areas | Several rental companies near the airport, most with free shuttles | The best way to explore Aso, where public transport is limited |
| Taxi | Accommodation near the airport | Metered | Easiest after an evening arrival with luggage |

Before you go: tips for American travelers
- Passport and visa-free entryUS passport holders can visit Japan as tourists for up to 90 days without a visa. Make sure your passport is valid for your whole stay.
- Register on Visit Japan WebEnter your immigration and customs details on Visit Japan Web before you fly. On arrival you show a QR code, which speeds up processing.
- Bring an International Driving PermitTo rent a car you'll need an International Driving Permit (IDP) plus your US driver's license and passport. In the US, IDPs are issued by AAA; get yours before you leave, as you can't get one in Japan. Japan drives on the left, with the steering wheel on the right, so take it slowly at first, especially when turning.
- Plan around the seasonsJapan's seasons are a lot like Seattle's, but summers are much hotter and more humid. From December to February, Aso can be icy or snowy, so ask the rental company for winter tires. June to July is the rainy season, and typhoons can disrupt flights from about July to October. Spring cherry blossom and autumn leaves are the busiest times, so book early.
- Your plugs mostly fitJapan uses the same two flat pins (Type A) as the US, at 100V instead of 120V. Phone and laptop chargers work as they are, but three-prong plugs need an adapter, as many Japanese outlets don't take the third pin.
- Carry an IC card and some cashBuses and trains accept IC transit cards, but some country restaurants, small shops and car parks are still cash only. Carry some yen.
- Plan for jet lagJapan is 16 hours ahead of Seattle during daylight saving time and 17 hours ahead in winter. Keep the first day light, get outside in daylight, and leave the long drive to Aso for later in the trip.
Make it a bigger trip: Tokyo, Osaka and Kumamoto
Coming all the way across the Pacific, it's worth seeing more than one side of Japan. These two sample itineraries combine Tokyo, the Kansai region and Kumamoto, with a Stark House home at every stop. You'll have room to unpack, cook and do laundry, and travel more like a local.
Book a multi-city ticket for both itineraries, and add the domestic flights or Shinkansen inside Japan. Many travelers send big suitcases ahead to the next city with a luggage delivery service (takkyubin) and travel with just a day bag. Check with your host before sending luggage to your stay.
