About the Tokyo → Seoul route
Tokyo to Seoul is one of Asia's great short-haul workhorses — just 1,257 km and roughly 90 minutes in the air, which means you're barely at cruising altitude before the descent begins. It's the kind of route where you almost feel cheated buying a window seat. Korean Air (KE) and Asiana (OZ) dominate the full-service end, but low-cost carriers including Jin Air (LJ) and T'way Air (TW) have made real inroads. The passenger mix is genuinely interesting: Korean-Japanese business commuters, K-pop fans, food tourists, and a substantial number of people visiting family across both countries.
Why travel from Tokyo to Seoul?
Seoul rewards travelers who care about eating well and moving fast. Myeongdong alone is worth the flight — street food stalls, skincare shops, and enough foot traffic to make Tokyo's Shibuya feel calm. Beyond that, the pull from Japan is specific: Korean BBQ that hits differently when you're actually in Seoul, the Han River park scene, Bukchon Hanok Village, and a nightlife culture that runs several hours later than Tokyo's. Business travelers ride this route constantly for meetings between companies with operations in both markets. Korean-Japanese families make up a quietly large share of seats too — this isn't just a tourist route, it's a genuine people connector with real emotional weight behind it.

Practical tips for NRT → ICN
Spring (April-May) and autumn (October) deliver the best weather and manageable fares — avoid Golden Week from Japan, when prices spike hard in both directions. ICN is enormous but logical; immigration moves quickly if you're not in the last bank of wide-bodies to land. AREX express train runs from the airport direct to Seoul Station in around 43 minutes — skip the taxi. You'll want Korean Won on arrival; card acceptance is wide but not universal at markets. No visa required for Japanese passport holders for short stays. If you're booking LJ or TW, check baggage allowance carefully — carry-on limits are strict and enforcement is real.
