An avalanche at Madarao Kogen Ski Resort on Saturday, February 28, injured four people—including a 14-year-old boy—after five riders were caught on a popular powder run. All five were rescued within about an hour by a team of 21 professionals consisting of members from the police, fire personnel, ski patrol, and rescue dog teams.

Madarao Kogen is located in Myoko City in Niigata Prefecture on Japan’s main island of Honshu, roughly 150 miles northwest of Tokyo. The resort is known for its abundant snowfall, gladed terrain, and lift-accessed powder skiing. The slide occurred on the resort’s “Powder Line Course,” a run that descends from near the summit into mid-mountain terrain.
According to police and resort officials, a guest reported a suspected avalanche around 2:00 p.m., prompting the resort to notify local fire authorities. The avalanche occurred on Tochio Highlands Ski Area Course No.14 “Powder Line”” running from the upper mountain down toward mid-mountain. Five individuals, believed to have been snowboarding, were caught in the slide. All five were located and rescued by resort staff within approximately one hour. Four were transported to the hospital with serious injuries. They were identified by police as a 14-year-old Japanese boy, who sustained a pelvic fracture, his father, a man in his 40s, who broke several ribs, a Taiwanese woman in her 30s is believed to have broken her ankle, and a Taiwanese man in his 40s is also believed to have sustained an ankle fracture. As of the morning of March 1, authorities reported no additional missing persons or injuries.
At the time of the avalanche, light rain was falling, temperatures were around 4°C (39°F), and visibility was limited due to fog.
In a formal statement released Sunday, March 1, the resort confirmed the avalanche occurred at approximately 2:05 p.m. and described it as a rare, full-depth avalanche that originated high on the slope. A drone survey conducted at approximately 75 meters (246 feet) above the slope measured the slide as 185 meters (607 feet) wide, 600 meters (1,969 feet) long, and having a debris width of approximately 320 meters (1,050 feet).
Rescue and investigation teams conducted a full inspection from the crown area to the runout zone. Authorities also checked local lodging facilities and parking areas to confirm no additional guests were unaccounted for. Drone searches for signs of life and rescue dog sweeps of the debris field detected no further victims.
Resort officials, citing expert assessment shared among responding authorities, classified the avalanche as a full-depth avalanche—a type that releases down to the ground rather than within upper snow layers. Typically, full-depth avalanches are preceded by visible warning signs such as glide cracks on the snow surface. However, in this case, officials stated that no clear warning signs were observed during morning inspections.
The resort noted that higher-than-normal temperatures over the previous two days may have contributed to instability within the snowpack. The presence of standing trees along the avalanche path suggests the entire slope did not fail simultaneously but instead expanded progressively as it descended. Officials characterized the event as “a very rare occurrence” due to the absence of observable precursors.
Out of an abundance of caution, the resort suspended operations on three lifts scheduled to run the following day in order to prioritize safety and conduct search and investigation efforts. The affected terrain and lifts will reopen sequentially once safety has been confirmed. In its statement, Madarao Kogen expressed sympathy to those injured and pledged continued vigilance: “We will continue to strengthen our safety management systems and remain fully committed to providing a safe and secure environment for all guests.”
As investigations continue, authorities are working to determine the exact cause of the slide.
