Tokyo is 1 hour ahead of Shenzhen. Shenzhen uses China Standard Time (CST, UTC+8) while Tokyo uses Japan Standard Time (JST, UTC+9). When it's 12:00 PM in Shenzhen, it's 1:00 PM in Tokyo.
Neither China nor Japan observes daylight saving time, so the 1-hour difference remains constant year-round.
Best calling time: 9:00 AM - 5:00 PM Shenzhen time. This corresponds to 10:00 AM - 6:00 PM in Tokyo, covering the full Japanese business day.
Shenzhen is China's tech manufacturing capital, producing much of the world's electronics. Many Japanese companies have manufacturing partnerships in Shenzhen. The 1-hour time difference makes real-time collaboration convenient for business across both cities.
