London vs Tokyo

London

London's reputation for rain is somewhat exaggerated — it actually receives less annual rainfall than Sydney, Rome, or New York. However, drizzle is frequent and skies are often overcast. Pack layers and a waterproof jacket regardless of season.

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.

London

London's transport network (TfL) is extensive and efficient. Use a contactless bank card or Oyster card for the best fares — a daily cap of £8.10 (Zone 1-2) means you'll never overpay. Paper tickets cost significantly more. The Tube is the backbone, but buses and walking are often better for seeing the city.

Walkability: Central London is very walkable and walking is often faster than the Tube for short distances. The South Bank riverside walk from Westminster to Tower Bridge is one of Europe's best urban walks. Green parks (Hyde Park, St. James's Park, Regent's Park) connect neighborhoods beautifully on foot.

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.
