Earthquakes in Japan — June 2026

56 earthquakes were recorded in Japan during June 2026, an average of 1.9 per day.

56 reached magnitude 4 or above and 7 reached magnitude 5 or above. The average focal depth was 70 km.

The month's largest event in Japan was a magnitude 6.9 earthquake near Kuji, Japan on 24 June 2026 at 22:30 UTC. A magnitude 6.9 earthquake radiates roughly 337,605 tons of TNT equivalent in seismic energy.

That is close to the Japan monthly average of 57 events over the period we cover, and down from the 57 recorded the previous month.

77% of events here are shallow (under 70 km), 18% intermediate (70–300 km) and 5% deep-focus (over 300 km). That proportion of deep-focus events is the signature of a subduction zone: only a cold slab descending into the mantle stays brittle enough to rupture at those depths.

By band, the catalogue holds 49 in the magnitude 4 range, 6 in the magnitude 5 range, 1 in the magnitude 6 range.

Activity peaked on 16 June, when 4 events were recorded.

The month's largest events were M6.9 near Kuji, Japan on 24 June at 52 km; M5.8 near Yokoshiba, Japan on 26 June at 43 km; M5.8 near Noda, Japan on 27 June at 34 km.

That is close to the 57 events Japan averages per month across the 21 months on record.
