The monthly distribution of births of 7,960 schizophrenic patients in Tokyo born during the period of 1841-1950 was studied in comparison with that of a control population in Tokyo. A spring excess of schizophrenic births were found after 1901 as in previous studies in Western countries. Before 1900, however, there was no significant spring excess. The maximum excess of schizophrenic births occurred in May before 1900 and in April after 1901. The possibility of a shift in the seasonality of schizophrenic births was discussed.
对1841年至1950年期间在东京出生的7960名精神分裂症患者的出生月份分布进行了研究，并与东京的对照人群进行了比较。与西方国家之前的研究一样，1901年之后发现精神分裂症患者春季出生人数过多。然而，在1900年之前，春季出生人数并无显著过多。1900年之前精神分裂症患者出生人数最多的月份是五月，1901年之后是四月。文中讨论了精神分裂症患者出生季节性变化的可能性。
