According to a news article a drone that surveyed the Owakudani hot spring district at Hakoneyama recorded damage to three hot spring supply facilities; an exclusion zone for visitors was in effect due to increased seismic activity and an Alert Level raise to 2 (on a 5-level scale) on 6 May. At 1230 on 30 June a small-scale eruption occurred and the Alert Level was raised to 3.
On 1 July a news article noted another small-scale eruption (occurring between 0400 and 0500), and JMA reported that ash deposits were visible with the webcam. During fieldwork on 2 July, scientists confirmed new fumaroles at Owakudani that were vigorously emitting white plumes; the new fumaroles had formed during 29-30 June. White fumarolic plumes continued to be emitted through 5 July.
