Dublin to Tokyo Time

Dublin (Ireland) is an important regional economy, with key industries in diverse sectors including services and trade. Tokyo (Japan) is the world's third-largest economy, known for automotive, electronics, robotics, and precision instruments. With a 9-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.

Scheduling Meetings Between Dublin and Tokyo

With Tokyo 9 hours ahead of Dublin, there is minimal overlap in standard business hours. Most teams alternate meeting times to share the burden of early-morning or late-evening calls fairly. Business hours typically follow a 9 AM–5 PM schedule. Japanese business culture places high value on respect and hierarchy, with typical hours of 9 AM–6 PM. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.

Daylight Saving Time Considerations

Dublin observes Daylight Saving Time (GMT/IST), but Tokyo does not — it stays on JST year-round. This means the time difference between Dublin and Tokyo changes by 1 hour when Dublin switches clocks. During Ireland's summer, the gap is 8–10 hours instead of the standard 9 hours. Mark DST transition dates on your calendar to avoid missed meetings.

GMT (GMT/IST) stands for the timezone used in Dublin, Ireland (UTC+0). JST (JST) is the timezone used in Tokyo, Japan (UTC+9). Dublin is 9 hours behind Tokyo.

To convert GMT to JST, add 9 hours to GMT time. For example, GMT 9:00 AM = JST 6:00 PM.
