Tokyo to Reykjavik Time

Tokyo is the economic heart of the world's third-largest economy, known for automotive (Toyota, Honda), electronics (Sony), robotics, gaming (Nintendo), and precision manufacturing. Reykjavik (Iceland) is a small but highly connected Nordic island economy, known for fishing, geothermal energy, tourism, and aluminum smelting. 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 Tokyo and Reykjavik

With Reykjavik 9 hours behind Tokyo, 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. Japanese business culture places high value on respect and hierarchy, with typical hours of 9 AM–6 PM. Icelandic business hours are typically 9 AM–5 PM, with one of the world's highest internet penetration rates. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.

Daylight Saving Time Considerations

Neither Tokyo nor Reykjavik observes Daylight Saving Time — Tokyo stays on JST and Reykjavik stays on GMT year-round. This makes scheduling between these two cities simpler, as the 9-hour time difference remains constant throughout the year with no DST surprises.

Collaboration Tools & Workflow

With a 9-hour time difference, Tokyo and Reykjavik teams operate in a near "follow-the-sun" model. When one team logs off, the other picks up — enabling near-24-hour productivity on shared projects. The key challenge is handoff quality: teams should document decisions in shared tools (Notion, Confluence, Linear), record video updates with Loom, and write thorough pull request descriptions. Weekly all-hands meetings require someone to take an early morning or late evening call, so the best practice is to rotate this burden fairly between Tokyo and Reykjavik.

Remote Work Between Tokyo & Reykjavik

Tokyo, automotive (Toyota, and Reykjavik, a key city in Iceland, represent a common corridor for distributed teams navigating a 9-hour time difference. Remote workers and freelancers operating between these cities should plan their day around the overlap window — typically the late morning for one city and early morning or late afternoon for the other. Using a world clock widget, setting Slack status with local time, and blocking "no-meeting" deep work hours outside the overlap are essential practices for productive cross-timezone remote collaboration between Tokyo and Reykjavik.

JST (JST) stands for the timezone used in Tokyo, Japan (UTC+9). GMT (GMT) is the timezone used in Reykjavik, Iceland (UTC+0). Tokyo is 9 hours ahead of Reykjavik.

To convert JST to GMT, subtract 9 hours from JST time. For example, JST 9:00 AM = GMT 12:00 AM.
