Overview

Paris CDG to Tokyo Narita — one of the most-flown Europe-Asia long-hauls. Aircraft, sleep timing, and arrival-day light exposure are the three controllables that matter.

Jet lag

7-hour eastward shift on an overnight departure — the standard Asia-from-Europe pattern. Pre-flight schedule shifting helps; arrival-day morning light at Narita or in central Tokyo does the heavy lifting.

Best window side

Eastbound polar routing — the right side often catches sunrise late in the flight. For sleep, shade control beats view; pick the window you can fully blind.

Cabin humidity

787-9 (Air France, JAL) and A350-900 are notably better than 777 on a 12-hour eastbound. Worth filtering for these when booking.
