How to Distinguish
- The country domain ends with .je.
- License plates do not have a blue EU-style strip.(from 『【GeoGuessr】すべての国・地域解説 〜忘れられた国々〜』)
- Road-edge lines and stop lines are often yellow.
- The island is modest in size yet you’ll notice many buildings belonging to major banks.
- Street View quality tends to be poor (Gen 2).
License plates lack the blue strip (from 『【GeoGuessr】すべての国・地域解説 〜忘れられた国々〜』). The left edge may look slightly reddish.

Roadside markings and stop lines are frequently yellow.
Even though the island isn’t very urban, there are many bank buildings, such as Barclays or the Royal Bank of Canada (参考文献 Citi - Japan).

Look for roadside cycle-route signs shaped like the island itself.
