Here's a month-by-month look at prices on this route:
✈️ Which airlines fly from Seattle to Tokyo?
Four carriers fly daily nonstop Seattle to Tokyo — Delta and ANA serve Haneda; JAL and Hawaiian serve Narita.
The choice hinges on destination airport (HND saves 45-60 min), loyalty currency, and hard product — ANA’s The Room on 777-300ER days leads.

Delta owns the SEA-HND flagship — daily on the A330-900neo Delta One Suite, some A350-900.
After dismantling its Tokyo-Narita hub, Delta rebuilt its Asia gateway around Seattle-Haneda. The Delta One Suite competes with the Japanese carriers.
Anti-rec: the economy bag is 1x23kg versus 2x23kg, so pack accordingly.
Best for: SkyMiles loyalists, PNW tech business travelers, Delta One Suite, SEA SkyClub, Tokyo-focused HND trips

ANA brings trans-Pacific service polish — a Japanese meal program and a 787-9 cabin built at Everett, 30 miles north of SEA.
The Room on 777-300ER days leads the field: an enclosed 1-2-1 suite with a sliding door. Virgin Atlantic Flying Club books it at 31,500 points one-way.
Anti-rec: confirm equipment before paying The Room premium.
Best for: Star Alliance Gold, aviation enthusiasts, the Japanese meal program, Virgin Atlantic awards, The Room on 777-300ER days

JAL is the oneworld answer — daily SEA-NRT on the 787-9 Sky Suite.
JAL was the first Asian carrier at Sea-Tac, launching in 1959. The Sky Premium Economy (38-inch pitch) is the route's most under-priced cabin.
Alaska joined oneworld in 2021, so Mileage Plan earns full benefits on JAL metal, often beating AAdvantage.
Best for: oneworld earners, Alaska Mileage Plan elites, Sky Premium Economy, JR Pass holders via Narita Express

Hawaiian’s SEA-NRT is the value play — economy frequently lists $100-200 below ANA, Delta, and JAL.
The 2-cabin A330-200 widebody holds comfort over the 10-hour flight.
Since the 2024 Alaska acquisition, Mileage Plan works across both carriers, and the SEA-NRT-HNL routing is uniquely buildable from SEA.
Best for: budget trans-Pacific economy, Alaska Mileage Plan post-merger, Hawaiian loyalists, SEA-NRT-HNL hub builders
Mubboo verdict: Delta owns the SEA flagship with daily A330neo HND. ANA wins Japanese service polish. JAL is the oneworld Alaska pick. Hawaiian is the economy value play.

Compare all flights →📅 When should you book Seattle to Tokyo flights?
Book SEA-Tokyo 8-12 weeks ahead for cherry-blossom April, 6-8 weeks for shoulder months, 4-6 weeks for off-peak January-February.
April compresses fast — book by mid-February for late-March departures in the March 25 - April 8 bloom window. Obon (mid-August) lifts the eastbound return.
The May-June shoulder near $540-560 is the cleanest value window. December 20 - January 5 drives economy past $1,000.
M says: hot summer at 91°F, 3.39-inch precipitation; tsuyu ends mid-month.
If you're a family flying in summer, book by March — peak season fills up fast.
Budget travelers: shoulder season (Sep–Oct, Apr–May) offers the best balance of price and weather.
💡 This Jul: Summer-peak ramp. August Obon bookings closing.
🏙️ Why visit Tokyo?
Seattle's shortest Pacific hop opens onto a city that runs on rails, not roads. Where Seattle threads I-5 traffic, Tokyo moves 14 million people on the world's busiest rail network — a map-distant ward is a 12-minute hop.
The city wears two faces. Shinjuku and Roppongi are the neon, glass-tower Tokyo; walk ten minutes off the arteries and the shitamachi old town reappears in Asakusa and Yanaka.
History sits beside the future — Senso-ji, founded 645 AD, stands two stops from the 634-meter Skytree.
The surprise for first-timers is how organized and calm the city feels for its scale. Top restaurants book weeks ahead, and an empty table is usually reserved, not available.
What makes Tokyo worth the flight:
A first Tokyo trip from Seattle runs on three vectors.
Neighborhoods: Shibuya (Scramble Crossing, Shibuya Sky), Shinjuku (Golden Gai, Shinjuku Gyoen), Asakusa (Senso-ji), and Akihabara (electronics, anime).
Day trips: Nikko (2h), Hakone (1.5h, hot springs and Mt. Fuji), and Kamakura (1h, the Great Buddha).
Cherry blossom (late March - early April): Meguro River's lantern canopy, Yoyogi Park, and gated Shinjuku Gyoen.
Best neighborhoods to explore:
Tokyo's commercial center — skyscrapers, Golden Gai bars, and Shinjuku Gyoen. The world's busiest train station.
The iconic Scramble Crossing plus the Harajuku youth-fashion district. Shibuya Sky is the best sunset deck.
Old Tokyo (shitamachi) — Senso-ji (645 AD), Nakamise street, and traditional ryokan. Quieter at night.
Tokyo's nightlife and embassy district — Roppongi Hills, the Mori Art Museum, and an expat restaurant scene.
Electronics, anime, and manga capital — the Electric Town strip and Mandarake secondhand. PNW engineers make pilgrimages.
The central business district by Tokyo Station — the 1914 red-brick building and Imperial Palace gardens nearby.

Base Shinjuku for first-timers or business travelers needing JR connectivity, and Roppongi for upscale dining.
Choose Asakusa for old-Tokyo atmosphere, Akihabara or Shibuya for theme trips, and Marunouchi for Shinkansen-out itineraries.

🧳 What do you need to know before flying to Tokyo?
🛂 Do Americans need a visa for Tokyo?
US citizens do NOT need a visa for tourism stays up to 90 days in Japan — no ETIAS, no eVisa, no fee, no advance application.
At immigration, officers may request proof of onward travel and an accommodation address. Carry printed copies.
Visit Japan Web is the official pre-arrival system — register before flying for a QR code that speeds processing at HND or NRT.
Each traveler needs an individual passport. Verify current rules at travel.state.gov before booking.
🕐 What's the time difference?
Tokyo runs Japan Standard Time UTC+9 year-round — no daylight savings.
The practical offset: Tokyo is 16 hours ahead of Seattle in winter and 17 in summer. A 9am Seattle call is 1am Tokyo the next day.
Westbound crosses the International Date Line — depart Tuesday afternoon, arrive Wednesday afternoon. The flight loses a day going out and gains it back eastbound.
Most travelers find 3-5 days of jet-lag adjustment, with westbound the harder direction.
🚇 How do you get from the airport to the city?
Tokyo has two airports served by SEA carriers, and Haneda's Keikyu Line leads for speed and value.
| Airport / Option | Time | Cost | Best for |
|---|---|---|---|
| Keikyu Line to Shinagawa (HND) ✅ | 15 min | 300 JPY | Fastest from Haneda — direct to JR Yamanote |
| Tokyo Monorail to Hamamatsucho (HND) | 15-25 min | 500 JPY | Every 4-10 min, JR Yamanote connection |
| Narita Express to Tokyo Station (NRT) | 60 min | 3,070 JPY | JR Pass-eligible, every 30 min |
| Keisei Skyliner to Ueno (NRT) | 45 min | 2,580 JPY | Fastest from Narita — every 20-40 min |
Editor's pick: the Keikyu Line from HND for the fastest arrival; the Narita Express from NRT for JR Pass holders, running direct to Tokyo Station for onward Shinkansen.
💷 What about money and tipping?
Japan uses the Japanese yen (JPY / ¥), recently near 159 JPY per US dollar — check current rates, since they move.
Tokyo is more cash-friendly than most capitals — smaller shops, izakayas, and bathhouses are often cash-only. Carry ¥20,000-30,000.
Visa and Mastercard work widely; American Express is patchier. Use 7-Eleven or Japan Post Bank ATMs for reliable withdrawals. There is no tipping culture.

Search flights →🛫 Flying from Seattle — airport tips
SEA Concourse A — Delta international departures (Delta Air Lines)
- Delta Sky Club Concourse A flagship plus satellite club — among Delta's strongest lounge networks in the West.
- Delta One Suite priority check-in at Concourse A — separate security lane and dedicated path.
SEA South Satellite — ANA, JAL, Hawaiian international departures (ANA / JAL / Hawaiian)
- South Satellite requires an underground tram from the main terminal — allow 20-30 minutes for the transfer.
- ANA Lounges at the South Satellite via Star Alliance Gold — solid, though not ANA's home-HND quality.
HND Terminal 3 — Delta + ANA international arrivals (Delta / ANA)
- HND Terminal 3 is the international complex — a large modern facility serving Delta, ANA, and other foreign carriers.
- Keikyu Line station inside Terminal 3 — Shinagawa in 15 minutes for 300 JPY, the fastest central-Tokyo arrival.
NRT Terminal 1 + Terminal 2 — JAL + Hawaiian international arrivals (JAL / Hawaiian)
- JAL arrives Terminal 1 North (oneworld) — the terminal also hosts AA, BA, Cathay, and Qatar.
- Hawaiian arrives Terminal 2, connected to Terminal 1 by a free inter-terminal shuttle every 5 minutes.
HND + NRT transit windows for onward Japan domestic (All carriers)
- HND for onward Japan domestic — JAL uses Terminal 1 and ANA Terminal 2, a 5-minute monorail from international Terminal 3.
- NRT for onward Japan domestic is far less convenient; for Hokkaido or Osaka, HND saves substantial time.

💡 Insider tips: Seattle to Tokyo
Choose HND over NRT carriers for any Tokyo trip — saves 45-60 minMubboo original data
Delta and ANA fly to Haneda; JAL and Hawaiian fly to Narita. HND sits 15 km out via Keikyu Line in 30 minutes; NRT is 60 km out, so HND saves 45-60 minutes.
Anti-rec: do not pick a Narita carrier for a short Tokyo trip just to save on the fare.
Book ANA on 777-300ER days for The Room business cabinMubboo original data
ANA's 777-300ER The Room is among the best business cabins flying. ANA assigns SEA-HND on a 787-9 / 777-300ER rotation, so check the equipment code at booking.
Anti-rec: do not pay The Room premium without confirming the aircraft type.
Hawaiian economy lists $100-200 below the other three carriersMubboo original data
Hawaiian's SEA-NRT economy consistently lists $100-200 below the other three. We tracked fares across major booking platforms to confirm the gap holds across seasons.
The A330-200 widebody holds up over the 10-hour flight.
Use Virgin Atlantic Flying Club for ANA Business at 31,500 points
Virgin Atlantic Flying Club is the under-known sweet spot for ANA Business — a 31,500-point one-way SEA-Tokyo redemption. Transfer Amex, Citi, or Chase points at 1:1.
Anti-rec: confirm partner award availability before transferring — inventory is search-only.
Afternoon westbound departure makes the sleep math work
Delta's SEA-HND departs late afternoon, arriving mid-afternoon next day — 6-8 hours of usable air-sleep. Eastbound departs morning and lands Seattle the same calendar morning.
The 16-17 hour westbound shift is the harder direction, needing 3-5 days.
May-June post-sakura shoulder is the value window at $540-560Mubboo original data
May and June are the cheapest months at $540-560 round-trip. Tuesday and Wednesday departures save $80-150 versus Friday or Sunday.
Book 6-8 weeks ahead for the floor.
ANA, JAL, Hawaiian allow 2x23kg checked free; Delta only 1x23kg
ANA, JAL, and Hawaiian allow 2 x 23 kg checked free; Delta allows only 1 x 23 kg, with the second at $100.
Anti-rec: Basic Economy excludes the first checked bag on US carriers — verify before booking.
👥 Who flies this route — and what they should know
PNW powder skier doing SEA-Sapporo onward (Hokkaido winter trip)
Featured this monthRecommended: Hawaiian SEA-NRT economy for value, onward JAL or ANA domestic to Sapporo for Niseko. ANA and JAL allow a ski bag with no extra fee; Hawaiian carries it as a standard checked bag.
Anti-rec: confirm the ski-bag allowance — some Hawaiian Basic fares charge overweight over 50 lbs.
Seattle tech business traveler (Microsoft / Amazon / Boeing engineer visiting a Tokyo office)
Recommended: Delta One Suite on the A330-900neo SEA-HND, late-afternoon departure. Arrive Haneda mid-afternoon, Keikyu Line to Shinagawa, base in Marunouchi or Roppongi. Delta corporate contracts run strongest for PNW tech HQs.
Anti-rec: do not book a morning meeting off an afternoon departure while skipping the acclimatization night.
Boeing Everett aviation enthusiast / aerospace supplier business traveler
Recommended: ANA on 777-300ER The Room when assigned. ANA's 787-9 and 777-300ER deliveries happen at Boeing Everett, 30 miles north of SEA. Book it with Virgin Atlantic Flying Club at 31,500 points one-way Business.
Anti-rec: confirm aircraft type before paying The Room premium — the rotation can flip.
Alaska Mileage Plan elite chasing oneworld JAL award redemption
Recommended: JAL Sky Suite SEA-NRT with an Alaska Mileage Plan award. Alaska joined oneworld in 2021, so Mileage Plan earns full benefits on JAL metal. Arrive Narita, Narita Express to Tokyo Station, Shinkansen onward.
Anti-rec: check JAL Mileage Bank rates first — they can undercut Mileage Plan.
Delta SkyMiles optimizer redeeming the SEA-HND flagship
Recommended: Delta One Suite SEA-HND on a SkyMiles award, low saver date. Delta prices the flagship dynamically — on low dates the award beats cash value by a wide ratio. Transfer Amex or Chase points after confirming saver space.
Anti-rec: do not pay cash for the suite when saver space is open.
Akihabara hardware-engineer pilgrimage (PNW tech employee)
Recommended: Delta or ANA SEA-HND in Economy Plus or Premium Select. Akihabara is the capital of electronics and anime. HND to Akihabara is 30 minutes via Keikyu and JR Yamanote; Narita is 90 minutes each way.
Anti-rec: do not book Narita for a 3-day Akihabara trip — transits eat half a day.
Multi-stop Tokyo-Kyoto-Osaka Shinkansen circuit traveler
Recommended: JAL SEA-NRT with a JR Pass, or ANA SEA-HND with onward Shinkansen. The Golden Route (Tokyo + Kyoto + Osaka) is the highest-rated itinerary, and JAL via Narita has the cleanest JR Pass connection direct to Tokyo Station.
Anti-rec: do not book a 7-day trip for the circuit — minimum 10-12 days.
⚖️ Flight delayed or canceled?
EC 261/2004 does NOT apply on SEA-Tokyo — Japan is not in the EU.
Coverage falls under four frameworks.
1. US DOT covers tarmac delays over 3 hours and denied-boarding compensation up to $1,550 on long-haul.
2. Airline Conditions of Carriage govern rebooking, vouchers, and hotels; ANA and JAL rebook proactively.
3. The Montreal Convention covers checked bags up to ~$1,750 — file within 7 days for damage.
4. Trip-delay coverage on a Chase Sapphire Preferred or Capital One Venture X is the most useful net. Typhoon season (August-October) is the heaviest risk.
📱 Stay Connected — Travel eSIM for Japan
Free option: T-Mobile Magenta and Magenta Max and Verizon TravelPass at $12/day include Japan data — verify your plan first.
Japan runs strong 5G and 4G LTE on NTT Docomo, SoftBank, and au by KDDI — an eSIM is the cleanest setup for US travelers without an unlimited-Japan plan.
Airalo, Saily, Nomad, and Holafly sell Japan 7-30 day plans in the $10-30 range. Activate the QR code from hotel WiFi after landing.
🛡️ Travel Insurance — Higher Relevance for Multi-Region Japan Itineraries
Free option: Chase Sapphire Preferred and Capital One Venture X include trip-cancellation, baggage delay, and emergency medical evacuation when you pay the flight with the card — check existing coverage first.
Tokyo itself is routine — Shinjuku, Shibuya, and Roppongi are an extremely safe walking radius.
Travel insurance becomes more valuable on multi-region itineraries — typhoon-season risk from August to October and Hokkaido rental loops. EKTA covers cancel-for-any-reason, medical evacuation, and vehicle damage.
🚖 Airport Transfers & Ground Transit — Tokyo HND and NRT
Free option: The Keikyu Line at 300 JPY from HND is the best free-first option — 15 min to Shinagawa, every 4-10 min, running 5am to midnight. A pre-booked transfer is the upgrade for families.
HND-to-central-Tokyo: Keikyu Line at 300 JPY (fastest), Limousine Bus at 1,400 JPY, or a taxi at 8,000-12,000 JPY.
NRT-to-central-Tokyo: Narita Express at 3,070 JPY or Keisei Skyliner at 2,580 JPY. For families or 3+ bags, a pre-booked Welcome Pickups or Kiwitaxi transfer beats taxi queues.
