- 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.

- Culture Professional, industrial, and closely linked to Tokyo. Values long-term corporate stability.
- Lunch Break 12:00 PM - 1:00 PM.
