The Japan Meteorological Agency lifted all tsunami advisories for the nation's Pacific coastline on Monday [1, 2].
The removal of these alerts signals a reduction in immediate risk for coastal residents, though the agency maintains that the ocean remains unstable.
The advisories previously covered a vast stretch of the Pacific coast, extending from Okinawa and Amami through the Kanto region [1, 2]. This wide area of coverage indicated a significant regional threat that required coordinated monitoring across multiple prefectures.
Reports on the exact timing of the lift vary between sources. One report said the advisories were removed during the afternoon of June 8 [1], while another indicated the final lift occurred at 6:20 on June 9 [2].
Despite the official end of the advisories, officials warned that the danger has not completely vanished. The agency said that sea-level fluctuations could still occur and should be monitored [1].
"Continued caution is necessary regarding sea-level fluctuations," the agency said [1].
Local authorities have urged residents to remain vigilant when approaching the shoreline. The agency said it lifted all tsunami advisories at 6:20 on the 9th [2].
This sequence of alerts follows a period of heightened seismic activity in the Pacific region. The agency's decision to lift the advisories suggests that the immediate energy from the triggering event has dissipated enough to move out of the formal alert phase.

The lifting of tsunami advisories marks a transition from emergency response to a monitoring phase. While the formal threat level has decreased, the warning about sea-level fluctuations indicates that residual oceanic energy can still create hazardous conditions for swimmers and small craft, highlighting the unpredictable nature of post-seismic sea behavior.
