Last year Japan counted 50,801 bear sightings. This year started faster.

Bears killed 13 people in the year to March 2026, the most since the government began keeping count in 2008. By the end of June, the new fiscal year had already logged 12,628 sightings against 7,555 over the same three months a year earlier. Spring is a weak guide to what follows, though. The trouble comes in autumn.

Where the bears are

Sightings reported in each prefecture, FY2022 to FY2025. Akita and Iwate alone account for nearly half of them. The map shows raw counts, so the big northern prefectures run dark partly on size alone.

Then came October

Every report from Toyama, Niigata, Gunma, Saitama and Hokkaido across FY2025, played back a month at a time. These five prefectures publish their bear reports as open data. Most prefectures do not, so this is a sample. In April there were 64 reports. In October there were 1,795.

This year so far

Sightings are running 67% above the same months last year. The casualty numbers have not moved with them. Injuries are slightly down, 53 against 55. Six deaths against four is too small a gap to read much into.

Why last year was so bad

Two things had been building for years. Japan's bear population roughly tripled between 2012 and 2025, from an estimated 15,000 to 54,000. Over the same stretch the people who hunt them aged out. Fewer than 20,000 active bear hunters were left by 2025, down from more than 70,000 in the 1970s.

The third thing happened in a single season. The 2025 acorn and beechnut crop failed across Tohoku. Bears that would have fed in the mountains came down for apples, persimmons and rubbish, and they found towns. By November the government had sent soldiers to Akita to help deal with them.

What happens next depends on the autumn

None of that reset in April. The bears are still there, the hunters are still gone, and this spring is the highest on record by a wide margin.

Spring does not tell you much, though. FY2024 was running ahead of FY2025 at the end of June, 7,601 sightings to 7,555, and FY2025 still finished two and a half times larger. October alone brought 15,998. What settles the year is whether the acorns fail again, and nobody knows that yet.
