This article examines changing romantic relationships in contemporary Japanese society. It specifically investigates whether Japanese people in their twenties and thirties have become asexual; that is, whether they tend to have few sexual experiences or interests. Data were collected through an internet survey; this article uses a subsample of 9,940 respondents. The dependent variables were the number of lovers respondents had during and after junior high school; the independent variable was the respondents’ age. Regression analyses found a clear trend toward asexual behavior among young men (in their twenties and thirties). However, young women are not as asexual as the previous generation. This asexualization of men may have contributed to Japan’s sharply declining marriage and birth rates. If so, other Asian societies may learn lessons from Japan’s experiences in the future.

日本人变成无性恋了吗？爱在日本

本文探讨了当代日本社会中不断变化的浪漫关系。它专门调查了日本二三十岁的人是否已经成为无性恋者；也就是说，他们是否倾向于很少有性经历或兴趣。数据是通过互联网调查收集的；本文使用了 9,940 名受访者的子样本。因变量为初中和初中后的恋人人数；自变量是受访者的年龄。回归分析发现年轻男性（二十多岁和三十多岁）有明显的无性行为趋势。然而，年轻女性并不像上一代那样无性。男性的这种无性化可能是导致日本结婚率和出生率急剧下降的原因。如果是这样的话，
