Disaster Prevention Tech Company HiSR Detects Signs Related to 2026 Tokachi Region Southern Earthquake (M6.1)?
Disaster prevention tech company HiSR announced the detection of a significant increase in ionospheric electron content 2-3 days before the 2026 Tokachi region southern earthquake (M6.1). The company, which develops earthquake disaster prevention and mitigation using AI and geophysical data, is currently crowdfunding for further development.

Around 5:24 AM on April 27, 2026, an earthquake with a maximum seismic intensity of 5-strong (M6.1) occurred in the southern Tokachi region of Hokkaido. The hypocenter was approximately 80-83km deep, with seismic intensities of 5-strong observed in Urahoro Town and 5-weak in Niikappu Town, but it was not subject to aftershock warning information.
According to analysis by HiSR Inc. (Representative Director: Shinji Hirooka), a Chiba University-affiliated startup, a significant increase in ionospheric electron content (specifically, total electron content in the ionosphere) was observed spreading across Hokkaido and northeastern Japan 2-3 days before the earthquake. The anomaly level of the increase was close to 3σ, suggesting it was a very rare phenomenon. Past statistics show that for earthquakes with a magnitude of 6 or higher and a depth of less than 40km, ionospheric anomalies occur with a probability of 65-70%. While solar activity is well-known to cause fluctuations in ionospheric electrons, only minor disturbances were observed after a solar flare during this period, with no major fluctuations. However, since this earthquake was relatively deep at approximately 80-83km, the precursor showed a somewhat unclear (spatially diffused) tendency.
Our company will continue to work on scientific earthquake disaster prevention and mitigation for B2B and B2G, based on AI and various geophysical data. We hope that as many people as possible will learn about our activities and provide long-term support.
