Osaka Business Pulse
- Culture Slightly more pragmatic and direct than Tokyo. Known for a entrepreneurial spirit and "Kuidaore" (eat until you drop).
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Best times for calls are 10:00 AM - 11:30 AM and 2:00 PM - 4:30 PM. Osakans are known for being slightly more informal and direct than people in Tokyo, but standard Japanese business etiquette (punctuality, politeness) still applies strictly. Avoid the 12-1 PM lunch hour.
Seattle Business Pulse
- Culture Tech-heavy, casual, and values innovation and nature.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The "sweet spot" is 10:00 AM to 4:00 PM. Expect a casual professional environment (lots of tech-casual wear). Networking often happens over coffee; many locals are flexible with virtual meeting times but value their time in nature, so avoid late evening or weekend intrusions.
