1. The Kuroshio Current has returned to its normal path off Japan's Pacific coast, no longer flowing northward along northeastern Japan. This change may have contributed to an increase in fish catches at Choshi Fishing Port near Tokyo.
2. Autumn mackerel catches at Choshi Port this year have recovered and exceeded the amount caught in October 2024 by nearly four and a half times. Sardine catches from June to September this year were also significantly higher compared to the same period last year.
3. Researcher Kakehi Shigeho suggests that the change in the current's path may be allowing fish to return to habitats they occupied seven years ago. However, he cautions that global warming has caused a rise in sea temperatures, so the entire marine environment may not revert to its former state and continuous monitoring is necessary.
