Whether you are staying in Tokyo for a while and want to take a side trip, or you plan to continue your travels onward to/from South Korea—Tokyo and Seoul are separated by about 2.5 hours on a plane, and flights are often dirt cheap. Here’s how to find the best air deals between the two cities.
A number of (mainly Korean) low-cost carriers (LCCs) operate between Tokyo and Seoul, and prices are super reasonable in both directions. Osaka, Japan’s second-largest city, also has a large international airport, and LCC flights to Seoul leave daily—however, not quite as frequently as between Tokyo and Seoul.
How to find cheap flights between Tokyo and Seoul
A good place to start is a fare comparison site like Skyscanner.
| Route | Airline | One-way Fare | Date | |
|---|---|---|---|---|
| Tokyo Haneda => Gimpo International | Asiana Airlines | ¥30,332 | Feb 25, 2025 | Booking options |
 | ||||
However, it is worth cross-referencing the fares on Skyscanner and other comparison sites with those offered directly on airline websites. Sometimes, buying directly is cheaper or special offers are only available with the airline itself.
There are several low-cost carrier airlines that fly between Tokyo and Seoul, all with offers starting from as low as ¥1,000 for one-way fares. See more below. Legacy airlines including ANA, JAL, Korean Air and Asiana also fly between Seoul and Tokyo; however, these flights are usually in the hundreds of dollars, making them several times more expensive than the LCC offers.
Direct flights or layover?
When searching on comparison sites, opt for direct flights only. There is no convenient stopover for this short-distance flight and almost without exception, layovers on the Tokyo-Seoul route will make your flight not only longer, but also more expensive.
However, if you are on an Asia trip, Seoul can be a stepping stone on your way up from Japan, northbound for China or Russia. If you want to do Taipei, Shanghai, Seoul, and Tokyo, one-way flights also make more sense–and luckily there is no price penalty for not getting a return with the LCCs plying the Tokyo-Seoul route, which is the northernmost bit of this quartet.

Tokyo’s two airports: Narita or Haneda?
Most Tokyo flights for Seoul leave from Narita Airport. This is a bit of a bummer, as it is not only further away (it takes around 60–90 minutes to get there from central Tokyo), but is also more expensive to get there.
Pro tip: If you are traveling with lots of luggage, you can arrange to have it ported to/from the airport, making the transfer easier.
Haneda is by far the more convenient airport (around 30–45 minutes from central Tokyo), and depending on where you start from, the train fare should land you somewhere in the ¥500 to ¥1,000 range, while Narita will set you back around ¥1,000 to ¥3,500, depending on which option you choose.
In short, a flight leaving Narita that is only a few thousand yen cheaper than one leaving Haneda might not be worth it. It pays to add in your transfers before booking.
Note that Seoul also has two airports: Gimpo Airport is a bit closer to the city center of Seoul, making it a slightly more convenient option compared to Incheon, the larger of the two.
Bonus: The best time to visit Tokyo and Seoul
While their climates are generally quite similar, Seoul is overall a bit cooler and less humid than the more southerly Tokyo. Winter in Seoul can be quite cold for sightseeing, with temperatures dropping below 0 °C, but can still entice many in Tokyo with its Christmas illuminations, and indoor thermometers generally in the comfortable temperature range.
The best season is often thought to be spring, when you can witness the cherry blossom in both cities—late March to early April in Tokyo, and slightly later in Seoul. Autumn also usually brings pleasantly warm and dry weather in both cities.
Summer is best avoided in Tokyo, unless you are okay with tropical heat and humidity. Seoul is slightly less extreme, but also not the most pleasant. Plus, June is the rainy season in Japan, which almost seamlessly transitions into typhoon season from August to September (give or take a few weeks on both ends) and is best avoided.

Carbon offsetting stuff
If you’re keen to reduce your carbon footprint, consider planting a tree or two to help offset your flights between Seoul and Tokyo. We like Platbos Forest in South Africa, which charges about ¥1,000 to pop an indigenous tree into the ground on your behalf.
