Currently, a high morbidity of rotavirus diarrhea has been seen in children in developed and developing countries. Improvement of the vaccines is necessary in order to reduce the burden of diarrhea caused by rotavirus. A survey of rotavirus infection from diarrheal stool specimens in children of seven regions in Japan was conducted from 1984 to 1999. The present study discusses the survey results and reviews the national and international data of more than 23 papers and congress proceedings about rotavirus infection in Japan. We analyze the prevalence of rotavirus infection in acute diarrheal in- and outpatients, the distribution of rotavirus G-serotypes and surveillance data for seasonality and age groups in Japan. The data indicated that rotavirus is the most important cause of diarrhea in Japan among young children, with the prevalence ranging from approximately 9.7 to 88%. The most common rotavirus strains belonged to serotype G1, specifically since 1993. Serotypes G2, G3 and G4 had also been documented to be predominantly based in the area and year before 1992. However, untypeable rotavirus strains had been found each year, with a prevalence up to 56.7% which suggests that rare serotypes (except G1-4) or new serotypes might exist. Unexpectedly, in Tokyo and Sapporo from 1998 to 1999, G9 was found to be the first most prevailing serotype with a high prevalence of 52.9 and 71.4%, respectively. Despite these data from different geographic areas, the year under investigation was relatively clear in respect to seasonality, with a peak of rotavirus activity in late winter (February) through early spring (March). Age distribution had also characterized that the infection was predominant among children aged 1-2 years of age, although it was also common in children of 2-3 years. In addition, mixed infection with bacteria was documented.

“…In 23 studies from 21 regions of Japan, which were found through Medline, the rotavirus strains were characterized for G‐serotype also. 28–30,35,37–48 Table 3 showed the summary of rotavirus G‐types based on these studies. G1 serotype was the most common (58.1%), followed by G2 (7.9%) and G3 (7.7%).…”

Serotyping of group A rotaviruses obtained from stools of 158 diarrheic patients in Chiang Mai, Thailand, by ELISA with monoclonal antibodies revealed a yearly change in the prevalence of individual serotypes. Three unusual human rotavirus strains were isolated. Strain Mc35 had subgroup I-serotype 10 antigen and a long RNA electrophoretic type, a property hitherto found only in bovine rotaviruses. RNA-RNA hybridization tests showed that the strain is more closely related genetically to bovine than to human rotaviruses. Strain Mc323, although serologically closely related to serotype 9, had subgroup I specificity and a long RNA electrophoretic type, a characteristic common to nonhuman rotaviruses. Strain Mc345, with an aberrant RNA pattern possibly due to genome rearrangement, had the same antigenic specificity as Mc323. These 2 strains were genetically very closely related to each other and were more related to porcine than to human rotaviruses. These results provide insights into the evolutionary mechanisms of human rotaviruses.
