Two Personalities
Tokyo gives you range without friction. In one day you can watch the tuna trade at Toyosu, walk the cedar forest around Meiji Jingu, shop the backstreets of Daikanyama and end up eating grilled chicken skewers elbow to elbow with office workers in a lantern-lit Shinjuku alley. It is quiet in surprising ways: people speak softly on trains and phone calls are skipped entirely.
Seoul is built for dates. Han River parks fill with couples on blankets at sunset. Namsan's tower, with its fences of padlocks, is a local tradition for pairs. Photo studios invite you to dress up together for an hour. The old core holds five Joseon dynasty palaces framed by mountains, while Gangnam and Seongsu are all glass towers, boutiques and cafes.
Both feel safe after dark, which matters on a honeymoon when you want to wander without planning every step. Tokyo is more refined and reserved. Seoul is warmer, louder and a little more fun.
Flights From the US
Tokyo is the easiest place in Asia to reach from the US. Nonstop flights serve Haneda (HND) and Narita (NRT) from a long list of cities, including Los Angeles, San Francisco, Seattle, Dallas, Houston, Chicago, Atlanta, Detroit and the New York area, in roughly 11 to 14 hours westbound. Haneda is about half an hour from the center. From Narita, the Narita Express reaches Tokyo Station in about an hour.
Seoul's Incheon International Airport (ICN) also has nonstops from many US cities, including Los Angeles, San Francisco, Seattle, New York, Atlanta, Chicago, Dallas and Washington Dulles. The AREX express train reaches Seoul Station in under an hour. Incheon is a long ride from Gangnam, so leave plenty of time before your flight home.
The two are close enough to combine. Flights between Tokyo and Seoul take about two and a half hours. An open-jaw ticket avoids doubling back.
Seasons Compared
Spring and autumn are best in both cities. The timing lines up closely. Cherry blossoms usually peak in late March or the first days of April in Tokyo and in early April in Seoul, along the Han, Yeouido and Seokchon Lake. Fall color reaches Seoul's palace gardens and Namsan around late October or early November. It reaches Tokyo's parks in late November and early December.
Summer is hot and humid in both. Tokyo's rainy season usually runs from early June into mid July, with July and August often in the 90s Fahrenheit. Seoul's rainy season typically arrives in late June and lasts into late July, with heavy downpours.
Winter is where they differ most. Tokyo's winter is cold but sunny and rarely snowy, with the best odds of seeing Fuji from rooftops. Seoul is often well below freezing with cutting winds, though skies are clear and the cafes are cozy. Avoid Lunar New Year and Chuseok in Seoul if you want everything open.
Hotels and Neighborhoods
In Tokyo, pick a neighborhood by mood. Marunouchi and Otemachi are home to Aman Tokyo and the ryokan-style Hoshinoya Tokyo. The Peninsula Tokyo overlooks the Imperial Palace gardens in Hibiya. Shibuya and Ebisu feel younger. Asakusa offers an older Tokyo at lower prices. Rooms are small by American standards, so book a corner room or suite if space matters. Top hotels run about $700 to $1,500 or more a night, with good mid-range hotels at about $200 to $400.
In Seoul, Jongno and Gwanghwamun put you near the palaces, with Four Seasons Hotel Seoul near Gwanghwamun Square and hanok guesthouses in Bukchon and Seochon with heated floors. The Shilla Seoul sits on the slopes of Namsan with gardens and a large spa. Signiel Seoul occupies the upper floors of Lotte World Tower. Seongsu and Hannam-dong have a growing number of boutique hotels.
In both, splitting nights between an old and a new neighborhood works well. Prices are approximate.
What You Will Eat
Tokyo has one of the world's largest collections of Michelin-starred restaurants. Eat sushi at least once at a counter, where you watch the chef work. Try tempura fried in front of you, tonkatsu, ramen in a dozen styles and yakitori under the tracks at Yurakucho. Department store food halls, called depachika, are ideal for picnic shopping. The cocktail bars are among the most precise anywhere. Tipping is not expected.
Seoul's food is more communal and fiery. Grill samgyeopsal pork belly at your table, wrap it in lettuce with garlic and ssamjang and wash it down with soju. Graze at Gwangjang Market on bindaetteok, a crisp mung bean pancake, then knife-cut noodles. At a pojangmacha tent bar, locals eat spicy rice cakes and fishcake soup. Fried chicken and beer, called chimaek, makes a cheerful river picnic. Seoul also has strong modern Korean tasting menus and a huge cafe culture.
If one meal will define your trip, Tokyo has the edge. For fun, everyday eating, Seoul is hard to beat.
Romantic Days Out
In Tokyo, start early at Senso-ji in Asakusa before the shops open, when the incense smoke and lanterns are yours alone. Take a water bus down the Sumida River to Hama-rikyu garden for matcha in a teahouse on a pond. At dusk, ride up to Shibuya Sky above the famous crossing. Spend an evening in the tiny bars of Golden Gai or Omoide Yokocho. Visit teamLab Planets for immersive digital art.
In Seoul, rent hanbok near Gyeongbokgung Palace, which usually gets you into the royal palaces free. Watch the guard-changing ceremony too. Book the guided tour of the Secret Garden at Changdeokgung, which has limited daily entry. Walk the alleys of Bukchon quietly, respecting visiting hours for residents. Ride the cable car up Namsan at dusk. Picnic at Banpo to see the Moonlight Rainbow Fountain on spring to fall evenings. Hike Bukhansan or Inwangsan, then soak in a jjimjilbang.
Practical Differences
Getting around is easy in both, with a few quirks. In Tokyo, load a Suica or Pasmo card into your phone wallet and tap in and out. Taxis are clean but pricey for long rides. In Seoul, buy a T-money card at a convenience store. Use Kakao T for taxis and keep addresses in Korean, since drivers rarely speak much English. Google Maps does not provide walking directions in Korea, so download Naver Map or KakaoMap.
Payments differ slightly. Tokyo is mostly cashless, but carry some yen for small shrines and older restaurants. Seoul takes cards nearly everywhere, though foreign cards occasionally fail in small shops, so keep some won as backup.
Public bins are rare in Tokyo, so carry a small bag for trash. In Seoul, many palaces and museums close one weekday, typically Monday or Tuesday. In both, tell your hotel you are on honeymoon. Japanese and Korean hotels often respond with a thoughtful touch.
Where Each City Leads Next
The best way to choose may be to look at what comes after the city.
Tokyo is the gateway to the classic Japan honeymoon. Most couples give it three or four nights, then continue to Hakone for a hot-spring night, Kyoto for temples and perhaps Kanazawa or Naoshima. Day trips to Kamakura's giant bronze Buddha and Nikko's shrines are easy.
Seoul leads to a different kind of trip. Give it three or four days, then fly about an hour from Gimpo Airport to Jeju for volcanic coastline, crater sunrises and black pork dinners, or head to Busan for a seaside city.
On a two-week honeymoon you can do both: four nights in Seoul, a short flight to Tokyo and the rest in Japan. Start in Seoul for its energy, then finish with Japan's quieter rhythm of gardens and ryokan baths.
