From 2001 to 2010, 17,392 Japanese cats were examined for feline coronavirus (FCoV) antibodies. The seroprevalence of purebreds (66.7%) was higher than that of random breds (31.2%). Seroprevalence increased greatly in purebreds by three months of age, while it did not fluctuate greatly in random breds with aging, indicating that cattery environments can contribute to FCoV epidemics. Purebreds from northern regions of Japan were likely to be seropositive (76.6% in Hokkaido, 80.0% in Tohoku), indicating cattery cats in cold climates might be more closely confined. Among purebreds, the American shorthair, Himalayan, Oriental, Persian, and Siamese showed low seroprevalence, while the American curl, Maine coon, Norwegian forest cat, ragdoll and Scottish fold showed high seroprevalence. There would also be breed-related differences in Japan similar to the previous studies in Australia.
2001年至2010年期间，对17392只日本猫进行了猫冠状病毒（FCoV）抗体检测。纯种猫的血清阳性率（66.7%）高于杂种猫（31.2%）。纯种猫在3月龄时血清阳性率大幅上升，而杂种猫随年龄增长血清阳性率波动不大，这表明养猫环境可能导致FCoV流行。日本北部地区的纯种猫血清阳性可能性较大（北海道为76.6%，东北地区为80.0%），这表明寒冷气候下养猫场的猫可能饲养环境更为封闭。在纯种猫中，美国短毛猫、喜马拉雅猫、东方猫、波斯猫和暹罗猫的血清阳性率较低，而美国卷耳猫、缅因库恩猫、挪威森林猫、布偶猫和苏格兰折耳猫的血清阳性率较高。与澳大利亚之前的研究类似，日本也存在品种相关差异。
