日本百岁及以上老人首次超过10万

日本百岁及以上老人数量首次突破10万大关，达到107677人，成为全球此年龄段人口最多的国家1。这一人口里程碑反映出日本面临的深层人口危机，同时也突显了该国在延长寿命方面的成就。

在超过10万的百岁老人中，女性占比达88%1。日本最年长的女性是114岁的岸本富代，最年长的男性是112岁的加藤光，分别来自京都市和熊本县1。百岁老人数量的增长速度之快令人瞩目，1963年日本仅有153名百岁老人，到1981年增至1000人，1998年达到10000人1。

然而，日本的人口前景却令人担忧。该国总生育率已跌至历史低位1.14，远低于人口替代所需的2.11。日本政府已将人口下降问题定性为"宁静的紧急状态"1。根据预测，日本人口将从2008年的峰值1.28亿下降至2070年的约8700万，降幅高达30%1。同时，65岁及以上人口所占比例也在上升，目前约为30%，预计到2070年将接近40%1。

Japan has crossed a historic demographic milestone, with the number of people aged 100 or older reaching 107,677—the highest figure globally 1. This represents the first time the country's centenarian population has exceeded 100,000 1. Women comprise 88 percent of this group, with the oldest person on record being 114-year-old Kishimoto Tomio from Kyoto, while the oldest man is Kato Hikaru, aged 112, from Kumamoto Prefecture 1.

The surge in centenarians underscores Japan's profound demographic transformation. The country's total fertility rate has plummeted to a historic low of 1.14, well below the 2.1 replacement level needed to maintain population stability 1. Japan's population peaked in 2008 at 128 million, but is projected to decline by 30 percent by 2070, falling to 87 million 1. Citizens aged 65 and over currently account for approximately 30 percent of the population, a proportion expected to approach 40 percent by 2070 1. Health Minister Kenichiro Ueno expressed relief that "so many people are living long, healthy and active lives" 1. The centenarian population has grown dramatically since 1963, when Japan had only 153 people aged 100 or older, rising to 1,000 by 1981 and 10,000 by 1998 1.
