日本千叶县近日遭遇创纪录强降雨，至少造成4人死亡，另有5人受伤及1人失踪[1][2]。本次暴雨的每小时降雨量超过100毫米，创日本有气象记录以来最高水平[1]，约为当地8月平均降雨量的三倍[1]。千叶县知事Toshihito Kumagai表示，"这种情况即使按照日本历史气象标准来看，也是极其罕见的"[1]。气象部门将此描述为"创纪录水平的暴雨"[1]。
强降雨引发大范围灾情。道路和数十栋房屋被洪水淹没[2]，超过10万户居民被要求撤离[1]。电力供应受到严重影响，逾2万户失电[1]。成田机场有7000名旅客滞留[1]。数千人一度被困[2]。当地政府初期发布了最高级别五级紧急警报，随后降至四级[1]。根据预报，暴雨预计将持续至本周五晚些时候[1]。
Record-breaking torrential rain has struck Chiba Prefecture near Tokyo, resulting in at least four deaths and widespread disruption across the region [1][2]. The downpour brought rainfall exceeding 100 millimeters per hour—the highest precipitation rate ever recorded in Japan [1]. Local officials characterize the weather event as extraordinary; Chiba Governor Toshihito Kumagai stated that "this case was an extremely unusual situation, even by Japan's historical weather standards" [1]. Meteorological authorities have classified the phenomenon as an "unprecedented level of heavy rain," with precipitation levels approximately three times the average August rainfall [1].
The disaster has forced widespread evacuations and caused significant infrastructure damage. More than 100,000 residents have been ordered to evacuate, while over 20,000 households lost electrical power [1]. Roads and dozens of buildings have been flooded, trapping thousands of people in the affected areas [2]. Additionally, 7,000 travelers became stranded at Narita Airport due to the severe weather conditions [1]. Five people have been injured [1], and one person remains missing [2]. The meteorological agency issued the highest level five emergency alert initially before downgrading it to level four, with heavy rain expected to continue through late Friday [1].
