Tokyo & London — Business & Scheduling Guide

Tokyo (Japan) is the world's third-largest economy, with key industries in automotive, electronics, robotics, and precision instruments. London (United Kingdom) is a leading center for finance and international trade, known for finance, insurance, media, and professional services.

Scheduling Meetings Between Tokyo and London

With London 9 hours behind Tokyo, there is minimal overlap in standard business hours. Most teams alternate meeting times to share the burden of early-morning or late-evening calls fairly. Japanese business culture places high value on respect and hierarchy, with typical hours of 9 AM–6 PM. British business culture values politeness and punctuality, with typical hours of 9 AM–5:30 PM. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.
