Marunouchi: the red brick and the boulevard
The restored 1914 station, a rooftop garden over the tracks, and the best street in the business district. This is a Claude-drafted route awaiting the editor's walk.

1. Tokyo Station Marunouchi facade
Start outside the red-brick front of 1914, the two domes restored to their original three-storey height in 2012 after wartime damage left them stunted for sixty years. Stand back across the plaza; the building only reads whole from a distance.

2. KITTE atrium
The old central post office, kept as a white triangular atrium with shops folded around it. Take the lift to the sixth-floor roof garden — free, open late, and the only place to stand level with the station roofs and watch the *Shinkansen* slide in and out below.

3. Marunouchi Naka-dori
The tree-lined boulevard that runs the length of the district — luxury frontages, public sculpture, café tables on the pavement. *-dori* means avenue; this is the one to walk slowly. Cars are barred at weekend lunchtimes and it becomes a long terrace.

4. Mitsubishi Ichigokan
A faithful 1894 red-brick office block, demolished in 1968 and rebuilt brick-for-brick in 2009 as a museum. The courtyard behind it is the quiet of the walk — a small garden hemmed by old brick, easy to miss from the boulevard.

5. Meiji Seimei Kan
A 1934 neoclassical insurance hall, one of the few pre-war buildings here to survive as itself rather than as a replica. Look up at the colonnade; the interior is open some days if you want the marble.

6. Yurakucho railway arches
End under the brick viaduct, where *izakaya* — pub-eateries — are wedged into the arches and the trains rumble overhead while you eat. Smoke, beer, grilled skewers. It's the city's other register, three minutes from the marble.
