Fukuoka Business Pulse
- Culture Energetic, entrepreneurial, and the gateway to Asia. Values innovation.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Ideal window is 10:00 AM to 11:30 AM. Fukuoka has a strong start-up culture and is slightly more informal than Tokyo, but standard Japanese etiquette (punctuality, politeness) still applies strictly. Avoid the 12-1 PM lunch hour for all professional inquiries.
San Francisco Business Pulse
- Culture Innovation-focused and casual. Values disruption, speed, and technical excellence.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Best reached between 10:00 AM and 4:00 PM. Expect a casual, tech-first vibe—informal language and dress are the norm. However, technical competence and speed are non-negotiable. Many in the Bay Area work non-traditional hours, but standard business times remain the safest bet.
