So, you're looking at a Chicago to Japan flight. It’s a beast. You’re basically sitting in a pressurized metal tube for thirteen hours, crossing the international date line, and hoping the person in 24C doesn't decide to do calisthenics in your personal space.
It's a long haul. O'Hare (ORD) is one of the few hubs in the world that serves as a direct gateway to both Tokyo Narita (NRT) and Tokyo Haneda (HND). That's a huge perk for Midwesterners. You don't have to deal with the soul-crushing layover in LAX or Seattle. You just get on the plane, eat some lukewarm noodles, watch three movies you’d never pay to see in a theater, and boom—you're in Japan. Well, "boom" is a strong word. It’s more of a slow, grueling crawl across the Pacific.
Most people obsess over the price. That makes sense. But honestly? The airline you pick matters way more than a $50 difference in fare. If you're flying United or American, you’re getting a standard US carrier experience. It’s fine. It’s functional. But if you manage to snag a seat on Japan Airlines (JAL) or All Nippon Airways (ANA), you’ve basically won the lottery. Even in economy, the legroom is better, the food is actually edible, and the service is on another level.
Which Airport Should You Actually Choose?
This is where people trip up. Tokyo has two main airports: Narita and Haneda.
Narita is way out in the sticks. It’s in Chiba Prefecture. If you land there, you’re looking at an hour-long train ride on the Narita Express or the Skyliner just to get into the city. It’s expensive and sort of a drag after a 13-hour flight. Haneda, on the other hand, is practically in the city. You can take a monorail or a local train and be at your hotel in Shinjuku or Shibuya in 30 minutes.
Most direct Chicago to Japan flight options from United and ANA tend to favor Haneda these days because it’s more convenient for business travelers. American Airlines often routes through Narita. If the price is the same, pick Haneda. Your future, jet-lagged self will thank you.

The Great Polar Route Mystery
Ever wonder why your flight path looks like a giant arch over Canada and Alaska on the seatback map? You aren't flying straight across the Pacific. It’s called the Great Circle route.
Because the Earth is a sphere (shoutout to the science teachers), the shortest distance between Chicago and Tokyo is actually up near the Arctic Circle. You’ll fly over Northern Canada, maybe catch a glimpse of some ice sheets, and then come down over the Russian coast or the Aleutian Islands. It's fascinating. It also means you spend a lot of time in areas with zero cell reception and very little light during the winter months.
Booking Strategies That Actually Work
Forget the "incognito window" myths. That’s mostly nonsense. The real trick to a Chicago to Japan flight is timing the "sweet spot" for transpacific fares.
Usually, that’s about four to six months out. If you try to book two weeks before, you’re going to pay through the nose. If you book a year out, the airlines haven't even finalized their fuel surcharges yet, so you might overpay.
- Tuesday and Wednesday departures. These are almost always cheaper. Everyone wants to leave on a Friday so they can start their vacation on Saturday morning. Don't be that person. Leave on a Tuesday. Use those extra savings for a high-end sushi dinner in Ginza.
- Watch the seasons. Cherry blossom season (late March to early April) is beautiful, but it's also the most expensive time to fly. Same goes for "Golden Week" in late April. If you want a deal, go in late January or February. It’s cold in Tokyo, but it’s a dry cold, and the crowds are nonexistent.
- The Zipair Factor. Keep an eye on Zipair. They are a low-cost carrier owned by JAL. While they don't fly direct from Chicago yet (you'd have to hop to the West Coast), their entry into the market has forced the big carriers to keep their prices somewhat competitive.
Jet Lag is a Physical Enemy
You are jumping 14 or 15 hours ahead, depending on Daylight Savings. Your body is going to think it’s 3:00 AM when it’s actually lunchtime in Tokyo.

The biggest mistake people make on the Chicago to Japan flight is sleeping the whole way. Don't do it. You need to align your sleep with Tokyo time the moment you sit down in that seat. If the flight leaves Chicago at noon, it’s already 2:00 or 3:00 AM the next day in Tokyo. You should try to nap early and then stay awake for the last half of the flight.
Hydration is also non-negotiable. The air in those cabins is drier than the Sahara. If you drink three Gin and Tonics, you’re going to feel like a raisin by the time you hit customs. Drink water. Bring a reusable bottle and ask the flight attendants to fill it up. They usually have a giant jug in the galley.
What to Expect at O'Hare
Terminal 5 is where the magic (and the chaos) happens. It’s been undergoing a massive renovation, so it’s actually decent now. There are better food options, more charging stations, and the security lines move... okay, they still move like molasses, but it’s better than it was in 2019.
If you have TSA PreCheck, make sure it’s on your boarding pass. It doesn't always work for international carriers unless they are partnered with the program. JAL and ANA are part of it, which is another reason to fly with them.
The Reality of Economy vs. Premium Economy
Let’s be real. Not everyone can drop $5,000 on a lie-flat Business Class pod.
On a Chicago to Japan flight, Premium Economy is actually the "sweet spot" for value. You get a much deeper recline, a leg rest, and usually better headphones. More importantly, you get off the plane faster. When there are 300 people trying to get through Japanese immigration at once, being in the first 50 makes a huge difference.
If you are stuck in standard economy, try to get an aisle seat in the middle section. If the flight isn't full, you might get lucky and have an empty middle seat next to you. Avoid the very back of the plane. The engines are louder, the turbulence feels worse, and you’re the last one to get your food choice. Nobody wants the "mystery pasta" because the beef sukiyaki ran out ten rows ahead of you.

Arrival and the "First Hour" Ritual
Once you land, the process is usually incredibly efficient. Japan takes pride in its logistics. You’ll go through quarantine, immigration, and customs.
Have your "Visit Japan Web" QR codes ready on your phone. It saves you from having to fill out those little paper slips with a borrowed pen.
After you clear customs, don't just wander out into the lobby. Stop at a currency exchange or an ATM. While Japan is much more credit-card friendly than it used to be, you still need cash for small shops and temple entrance fees. Grab a "Welcome Suica" or a "Pasmo Passport" card. These are IC cards you can tap for trains, buses, and even vending machines.
Actionable Steps for Your Journey
- Check your passport expiration date now. Japan requires your passport to be valid for the duration of your stay, but many airlines won't let you board if you have less than six months left.
- Download the airline app. This is the fastest way to get gate change notifications or to rebook if a blizzard hits O'Hare.
- Pack a "long-haul kit." Include noise-canceling headphones (crucial), an eye mask, a neck pillow that actually supports your head, and some decent lip balm.
- Book your airport transfer in advance. If you’re landing at Narita, look into the Keisei Skyliner or the Narita Express. Buying the ticket online can sometimes save you a few yen and a lot of headache.
- Notify your bank. Let them know you’re going to be in Japan so they don't freeze your card the first time you try to buy a high-tech heated toilet seat or a bowl of ramen.
Flying from Chicago to Japan is an endurance test, but it's the gateway to one of the most incredible cultures on Earth. Prep right, pick the right flight, and keep your fluids up. You'll be eating 7-Eleven egg salad sandwiches (which are weirdly gourmet in Japan) before you know it.
