Sakura safety flagged on video

A cherry tree can look perfect in a photo and still be rotten inside. That was the point of the April 10 video spreading online after a run of collapses at sakura spots in Tokyo, Fukuoka, and other parts of Japan. (youtube.com) This hit during the busiest part of hanami, the Japanese custom of cherry-blossom viewing, when parks fill with picnics, photographers, and tourists chasing peak bloom. Tokyo’s 2026 season officially started on March 19 and reached full bloom on March 28, which packed famous viewing routes just before the tree incidents. (nippon.com) The headline cases were in Tokyo. Two cherry trees collapsed around April 2 and April 3, including one at Kinuta Park in Setagaya and one along the Chidorigafuchi greenway, with no reported injuries but damaged fencing and immediate safety cordons. (apnews.com) (asahi.com) Tokyo’s problem is partly age. Many of the city’s famous Somei Yoshino cherry trees were planted during the postwar building boom of the 1960s, which means a huge share of the same generation is now old, brittle, and failing at the same time. (apnews.com)) The unsettling part is that some risky trees do not advertise the danger. At Kinuta Park, the tree that fell on April 2 had shown no obvious abnormality in the prior inspection and had only been marked “under observation.” (asahi.com) Inspectors are literally sounding out the trunks. In Tokyo and Fukuoka, arborists used hammers and follow-up equipment to listen for hollow sections, because a cavity inside the wood can turn a healthy-looking trunk into a shell. (ntv.co.jp) Fukuoka had its own warning on April 8, when a 15-meter cherry tree fell at Maizuru Park while people were gathered for blossom viewing. City officials said decay at the base was the suspected cause, and they launched emergency checks on about 1,000 cherry trees the next day. (ntv.co.jp) Tokyo widened its response too. After repeated falls at Kinuta Park, the metropolitan government began emergency inspections on April 9, and arborists checked about 5,000 trees taller than three meters there, finding seven with potential fall risk on the first day. (ntv.co.jp) This is not just a cherry-blossom-season fluke. Japan’s land ministry found 1,732 cases from April 2021 to November 2024 in which falling trees or branches in parks or from street trees caused injury or property damage, and a separate branch fall in western Tokyo in September 2024 killed a pedestrian. (asahi.com) The crowd piece matters because the most photogenic sakura routes are also the tightest ones. As petals started falling this week, places like the Meguro River and the area around Nakameguro Station were still drawing heavy foot traffic, which means a single closure or fallen trunk can turn a leisure stop into a bottleneck fast. (timeout.com) So the real travel rule this season is boring and practical: check park notices, city advisories, and cordoned areas before copying a social-media itinerary. A viral clip can tell you where the blossoms are, but only local officials can tell you whether the tree over your picnic sheet is one of the ones they are worried about. (youtube.com) (ntv.co.jp)
