Japan and South Korea in 14 Days: A Day-by-Day Itinerary

A couple came to us last year with a spreadsheet. Fourteen tabs, one per day, colour-coded — and somewhere around tab nine it had quietly grown into twenty-one days: four cities in Japan, three in Korea, an island bolted on the end. They weren't being greedy. They were being thorough. But what they'd actually built was a month-long endurance event, not a holiday, and the giveaway was the transitions: a suitcase repacked at 7 a.m. in a room where they still hadn't found the light switch.

We took it back to fourteen days and four hotels. Below is roughly what they travelled, with the places named.

If you're still deciding how long to go for, read our decision framework on 14 days versus 21 first — it works through what each version leaves out, whether the ferry makes sense, and who genuinely should take the extra week. Short version: twenty-one days spent adding depth is a gift; twenty-one days spent adding checkboxes is just fatigue with a longer flight home. This article assumes you've made that call and chosen fourteen. From here on it's the route itself.

The shape of the route

Three constraints drive everything, and they hold no matter where you're flying in from.

There is no rail link across the Korea Strait. No undersea tunnel, not now, not planned. Inside each country the trains are superb — the Tokaido Shinkansen that serves Tokyo–Kyoto–Osaka runs up to 285 km/h, which puts Tokyo–Kyoto at roughly 2h15 and Tokyo–Osaka at about 2h30 — but you cannot ride from Osaka to Seoul. And the high-speed sea option is gone: JR Kyushu's Queen Beetle hydrofoil was pulled from service in August 2024 after its bow cracked and took on water on three separate occasions, incidents the operator concealed for months. JR Kyushu quit the Japan–Korea fast-ferry business entirely in February 2025 and sold the vessel, which now runs harbour cruises in Busan. What's left between Fukuoka and Busan is conventional overnight sailings of five to six hours at limited frequency (full account here). On a fortnight, that settles it: you fly.

So cross exactly once, and cross west. Work your way from Tokyo down to Kansai, then step across from Osaka. Kansai–Incheon is the shortest hop available on this routing — around 1h50 to 2h25 in the air depending on carrier and winds. It isn't the shortest Japan–Korea hop in existence; Fukuoka–Incheon is about 566 km against Kansai–Incheon's 866 km, and Fukuoka–Busan is shorter still. But Fukuoka isn't on a Tokyo–Kyoto fortnight, and detouring there to save forty minutes in the air costs you a day on the ground.

Book it open-jaw. In through Tokyo, out of Busan or Seoul. Backtracking to Tokyo to fly to Korea wastes a day and makes you pay Japan's international departure tax twice.

Four bases across fourteen days: Tokyo, Kyoto, Seoul, Busan, with Osaka folded in as a morning rather than a hotel. Every extra base costs you a checkout, a schlep and a settle-in, and those three hours are stolen from the good part of the day.

Days 1–4: Tokyo

Day 1 — arrive. Whether you land at Haneda or Narita, do nothing ambitious. Get a Suica or Pasmo at the airport, eat something local within walking distance of the hotel, and go to bed at a normal local hour. If you're arriving from within Asia and have no time change to absorb, use the spare evening on Omoide Yokocho in Shinjuku — a lane of eight-seat yakitori counters under the tracks, smoke and all.

Day 2 — old Tokyo, early. Senso-ji in Asakusa at 7 a.m., before the shops on Nakamise-dori roll their shutters up and the temple courtyard belongs to about nine people. Walk north-west into Yanaka afterwards, one of the few districts that survived both the 1923 earthquake and the war: low wooden houses, a cemetery full of cherry trees, a shopping street where the shops are still shops. Finish at the Tsukiji Outer Market for a late lunch — the inner wholesale market moved to Toyosu, but the outer market's tamagoyaki and knife shops stayed.

Day 3 — the loud half. Meiji Jingu first thing: a Shinto shrine at the end of a gravel avenue through 70 hectares of planted forest, in the middle of the city. Out the south exit into Harajuku and down Omotesando, then Shibuya crossing. In the late afternoon, take the Inokashira line four stops to Shimokitazawa — second-hand shops, tiny record bars, no towers.

Day 4 — get out of the city. Two good options. Nikko, two hours north, for Toshogu: a mountain shrine complex of gilded, over-carved buildings buried in cedar forest, which is the exact opposite of everything you saw yesterday. Or Kamakura, an hour south, for the Great Buddha at Kotoku-in and a coastline. Nikko is the bigger day; Kamakura you can do half-heartedly and still enjoy.

Days 5–7: Kyoto and Nara

Day 5 — Shinkansen west. Take a morning train and you'll be in Kyoto for lunch at Nishiki Market — the covered arcade the city's chefs actually shop in; go for tsukemono, tofu and grilled skewers rather than a sit-down meal. Spend the late afternoon walking Hanamikoji in Gion as the lanterns come on. Don't chase geiko for photographs; the residents' association has spent years asking people not to, and the street is better without the scrum.

Day 6 — dawn, then bamboo. Fushimi Inari opens onto the mountain around the clock and costs nothing, so start there at first light: the vermilion torii tunnel runs for four kilometres uphill, and the difference between 6 a.m. and 10 a.m. is the difference between a shrine and a queue. Come back down for Kiyomizu-dera, which opens at 6 a.m. and charges ¥500 — a wooden veranda on 13-metre pillars over a hillside, then the Sannenzaka slope back down. Afternoon in Arashiyama: the bamboo grove, and Tenryu-ji's pond garden next door, which is the better of the two and the one people skip.

Day 7 — Nara, then a night's decision. Nara is 45 minutes from Kyoto. Todai-ji's Daibutsuden (¥800) holds a 15-metre bronze Buddha under what is still one of the world's largest wooden roofs, and the deer in the surrounding park bow for crackers, which is genuinely a learned behaviour and not a story. Back in Kyoto for a last night — or, if you'd rather trade a temple for a food city, move to Osaka this evening instead and sleep there.

Day 8: an Osaka morning, then the crossing

Even without a hotel night you get Osaka. Kuromon Ichiba Market for breakfast (grilled scallops, uni, fruit cut to order), Dotonbori for the canal and the Glico sign, kushikatsu in Shinsekai under the Tsutenkaku tower if there's time. Then the HARUKA limited express from Kyoto to Kansai Airport — ¥2,200 one-way on the discounted tourist ticket, reserved seat included.

The flight is short. The day isn't. Airport transfer, check-in, immigration on arrival, bags, and the run into Seoul from Incheon add up to most of a working day no matter how the timetable looks. Plan nothing for the evening beyond finding dinner near the hotel, and treat the crossing as a day you spend rather than a day you gain.

Book an afternoon departure rather than a dawn one. You'll get your Osaka morning, and you'll still arrive in Seoul in time to eat.

Days 9–11: Seoul (four nights)

Day 9 — palaces and market food. Gyeongbokgung opens at 9, costs ₩3,000, and closes on Tuesdays. The royal guard changing ceremony runs at 10:00 and 14:00 at the plaza in front of Heungnyemun and takes about twenty minutes; it's free to watch from outside the gates, and admission is waived entirely if you're wearing hanbok. Walk east into Bukchon Hanok Village mid-morning, then Gwangjang Market for lunch: bindaetteok, the mung-bean pancakes fried in front of you, around ₩5,000; mayak gimbap around ₩4,000; knife-cut kalguksu about ₩7,000. Evening in Ikseon-dong, a grid of 1920s hanok alleys now full of small bars.

Day 10 — the modern city. Changdeokgung in the morning for the Huwon secret garden, which needs a timed ticket and is worth the faff. Then Euljiro — print shops and machine-tool suppliers at street level, cocktail bars up unmarked staircases above them. Namsan and N Seoul Tower at dusk if the air is clear; the walk up through Namsan Park beats the cable car.

Day 11 — pick your Seoul. Three honest choices. The DMZ, on a half- or full-day tour, which is not a scenic outing and shouldn't be sold as one but is the single most affecting thing you can do from Seoul. Bukhansan, a granite ridge inside the city limits with a two-to-four-hour scramble and a view back over twenty million people. Or a slow day: Noryangjin fish market in the morning, an afternoon in Hongdae, a late night wherever it takes you.

Days 12–14: Busan

Day 12 — KTX south. Seoul to Busan is about two and a half to three hours by KTX, ₩59,800 in standard class one-way. Arrive by lunchtime and go straight to Jagalchi, Korea's largest fish market: buy on the ground floor, have it prepared upstairs. Afternoon at Gamcheon Culture Village — a hillside of houses painted in blocks of colour, originally a refugee settlement from the Korean War, now a maze of stairways with a view down onto the harbour. Free to walk; buy the stamp map at the entrance and it makes sense.

Day 13 — coast. Haedong Yonggungsa at sunrise: a Buddhist temple on the rocks at the water's edge on the eastern outskirts, and the rare temple built for the sea rather than the mountains. Then Haeundae beach, and Gwangalli in the evening for the bridge lit up over the water. If you want quieter, swap Haeundae for Huinnyeoul Culture Village on Yeongdo — cliffside lanes above the shipyards.

Day 14 — out. Fly home from Gimhae (PUS), or connect back through Incheon on the KTX if the fare works better. Either way you've flown once between countries, changed hotels three times in fourteen days, and seen five cities properly instead of nine badly.

Do the rail passes pay off? Mostly no

A two-country rail itinerary is exactly where people buy passes on autopilot, so run the numbers.

Japan. The 7-day Japan Rail Pass is ¥50,000 through 30 September 2026, unchanged on the official site afterwards though overseas agencies add ¥3,000–5,000 from 1 October. Now price this route point-to-point: Tokyo–Kyoto on a Hikari is about ¥13,850 reserved, a Kyoto–Nara return is roughly ¥1,500, Kyoto–Osaka is under ¥600, and the HARUKA to Kansai Airport is ¥2,200. That's around ¥18,000. The pass loses by about ¥30,000, and no amount of local JR hopping in Tokyo closes that gap. On a Tokyo-to-Kansai fortnight, a 7-day JR Pass does not pay for itself. It starts to make sense only if you push much further west — Hiroshima, Fukuoka — inside seven days. Our breakdown of when the JR Pass beats individual tickets has the full maths, and the official price list is the only figure worth trusting.

Korea. The current product is the KORAIL Pass — you'll still see it called the "KR Pass" in older guides, which is the legacy name. A 3-day pass runs about ₩121,000; a Seoul–Busan return in standard class is ₩119,600. That's a dead heat, so buy point-to-point unless you're adding a Gyeongju stop or a third city, at which point the pass wins immediately.

The entry admin, condensed

This is the part nobody puts in the Instagram caption: two countries means two sets of entry paperwork, and every extra border crossing repeats it.

Japan grants visa-free entry as a "Temporary Visitor" — 90 days for many nationalities, shorter for some, and the exact terms are worth checking against the Ministry of Foreign Affairs for your own passport rather than assuming. The officer at the desk sets your actual permitted stay and can ask for proof of onward travel and funds, so have both to hand. There's no meaningful tourist extension. Before you fly, register on Visit Japan Web to get your immigration and customs QR codes — one setup per entry.

Japan's departure tax went from ¥1,000 to ¥3,000 per person for departures from 1 July 2026, with tickets issued on or before 30 June 2026 keeping the old rate. Air and sea carriers collect it inside the ticket price, so there's nothing to pay at a counter, and infants under two are exempt (National Tax Agency). It's charged every time you fly out of Japan — which is the real cost of a Japan–Korea–Japan zigzag.

Korea waives the K-ETA pre-authorisation for around two dozen countries and regions from 1 January to 31 December 2026. Published totals vary with how the list is enumerated, so work from the list rather than a number: Japan, Taiwan, Hong Kong, Singapore and Macao; the United States and Canada; Australia and New Zealand; the UK; and a group of European countries including Germany, France, Italy, the Netherlands, Spain, Poland, Sweden, Finland, Norway, Belgium, Denmark, Austria, Switzerland and Liechtenstein. That is not all of Europe and not all of the EU — a Portuguese, Irish, Greek or Czech passport still needs a K-ETA — so check yours on the official portal before you book. No extension past 31 December 2026 has been confirmed either, so if you're travelling in 2027, re-check before booking.

Now the K-ETA and e-Arrival Card interaction, which runs opposite to what you'd expect. Travellers not subject to K-ETA must submit the online e-Arrival Card, filed up to three days before entry — the day of arrival, or one or two days prior, Korean Standard Time. But applying for a K-ETA voluntarily, even though you're exempt, releases you from the e-Arrival Card requirement (KPMG). If you cross into Korea more than once, or expect to come back within the K-ETA's validity, that's a genuinely useful trick: one application instead of a form every trip. The e-Arrival Card launched on 24 February 2025 and paper forms were accepted until December 2025, so from 1 January 2026 it's electronic only. Visa-free stay lengths vary by nationality — 90 days for many, 180 for Canadians — so check yours. Our first trip to South Korea guide covers the rest of the pre-flight checklist.

Where Jeju fits — and where it doesn't

Both things are true, and they don't contradict each other. On a Korea-focused trip, Jeju is an excellent opening chapter: a triple-UNESCO volcanic island with lava tubes, a tuff cone you climb for sunrise, and the haenyeo free-diving culture. It earns three nights and rewards them.

On a two-country fortnight, it's a genuine cut. A domestic flight, an island that needs 2–3 nights to justify itself, and a route that already has one international crossing in it — the arithmetic doesn't work. Save it, and go back for Korea properly.

Which is also why our 8 Days: Essential of Korea is built the way it is: Jeju, then Busan, then Seoul, in that order, with a private driver on the island because the sites are genuinely spread out. For a combined fortnight you'd run its Busan–Seoul spine and keep Jeju for the return trip. For a Korea-only trip, take it whole.

Timing

Both countries share the same two peak windows, so you don't have to compromise between them. Cherry blossom lands roughly late March to early April in both, though the exact bloom moves year to year — check the current forecast before locking dates. Autumn foliage runs October into November, and it's the better bet for a first visit: comfortable walking weather, clear light, and thinner crowds than blossom season. Summer brings Japan's rainy season and Korea's monsoon in overlapping succession. Winter is quiet and cheap, and Busan stays mild while Seoul does not.

Book it as one trip, not two

The reason this route works is that it's one itinerary rather than two holidays stapled together — one border crossing, three hotel changes, and a Japan leg that deliberately ends where the flight to Korea leaves from.

That's also how we build it. The Japan half of the fortnight is essentially our 9-day A Passage Through Japan — Tokyo, Kyoto, Nara, Osaka, with a private guide in English or Spanish, a tea ceremony in kimono, and the Shinkansen legs already ticketed — trimmed by a night and extended across the strait with a Seoul–Busan leg on the Korean side. If you'd rather give Japan the full run and come back for Korea another time, Japan of a Thousand Wonders is the 16-day version, with Kanazawa, Takayama, Shirakawa-go, Hiroshima and Miyajima in it.

Tell us your dates and which of the fourteen days above you'd fight for, and we'll build the version that fits them — starting with that Japan backbone and stitching the Korea leg on from there.
