London, United Kingdom, uses the Europe/London time zone, BST (UTC+1) until 25 October 2026. Tokyo, Japan, uses the Asia/Tokyo time zone, JST (UTC+9).

Both are named IANA time zones, so London and Tokyo follow their own daylight saving rules for the date you choose instead of a fixed offset. That is why the gap between them can change by an hour at different times of the year.
