Syncing between London and Tokyo is challenging due to the 9 hours offset. Teams should prioritize asynchronous communication or specific 'handover' windows.
London Business Pulse
- Culture London business culture is generally formal but collaborative. "Flexi-Fridays" are common in the summer.
- Lunch Break Typically 1:00 PM - 2:00 PM.
- Pro Tip Avoid calling after 4:30 PM on Fridays as many offices wind down early for the weekend. Mid-week (Tuesday to Thursday) between 10 AM and 4 PM is the "Golden Window" for reaching decision-makers. Always start with a brief polite inquiry about their day before diving into business.
Tokyo Business Pulse
- Culture Consensus-based and very formal. Respect for hierarchy and "Meishi KΕkan" (business card exchange) are central.
- Lunch Break Strictly 12:00 PM - 1:00 PM.
- Pro Tip The most effective window is 10:00 AM to 11:30 AM. Avoid the strictly observed 12-1 PM lunch hour at all costs. Late afternoon calls (4 PM - 5:30 PM) are also acceptable, but ensure you follow formal protocols and hierarchy if multiple stakeholders are on the line.
