Tokyo vs Seoul

Tokyo

Tokyo has four distinct seasons. Summers are hot and humid, winters are mild and dry. Spring and fall are the most pleasant times to visit.

Seoul

Seoul has a humid continental climate with four very distinct seasons. Summers are hot and humid with a monsoon season (jangma) in July. Winters are cold and dry with Siberian air masses. Spring and autumn are short but spectacular.

Tokyo

Tokyo has the world's best public transit system. The train and subway network will get you within walking distance of virtually anything. Taxis are clean and honest but expensive.

Walkability: High within neighborhoods. The city is sprawling so you'll use transit between areas, but individual districts like Shibuya, Shinjuku, Asakusa, and Ginza are very walkable.

Seoul

Seoul has one of the world's best public transit systems. The subway is clean, punctual, and covers virtually everywhere you need to go. Get a T-money card (reloadable transit card) at any convenience store for 2,500 KRW and load it up. It works on subways, buses, and even taxis and convenience stores.

Walkability: Seoul is moderately walkable but spread out. The historic core (Jongno, Insadong, Bukchon) is compact and pleasant on foot. Hilly terrain in some neighborhoods (Bukchon, Itaewon) can be tiring. Use the subway to cover distances between districts and walk within them.
