Reykjavik to Tokyo Time

Reykjavik (Iceland) is a small but highly connected Nordic island economy, with key industries in fishing, geothermal energy, tourism, and aluminum smelting. 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. 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 Reykjavik and Tokyo

With Tokyo 9 hours ahead of Reykjavik, 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. Icelandic business hours are typically 9 AM–5 PM, with one of the world's highest internet penetration rates. 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

Neither Reykjavik nor Tokyo observes Daylight Saving Time — Reykjavik stays on GMT and Tokyo stays on JST 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, Reykjavik and Tokyo 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 Reykjavik and Tokyo.

Remote Work Between Reykjavik & Tokyo

Reykjavik, a key city in Iceland, and Tokyo, automotive (Toyota, 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 Reykjavik and Tokyo.

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