In order to compare the subtype distribution of central nervous system (CNS) and miscellaneous intracranial and intraspinal neoplasms in children and adolescents between Japan and other countries, we extracted information on cancer incidence in children and adolescents from the third volume of the International Incidence of Childhood Cancer series (IICC-3)(1). The IICC-3 reports the number or incidence rates of cancers occurring in childhood and adolescence, collected from cancer registries (regional or national) worldwide. We analyzed CNS and miscellaneous intracranial and intraspinal neoplasms incidence in four countries in Asia (Japan, China, the Republic of Korea and Thailand), two countries in Africa (Egypt and Uganda), four countries in the Americas (North: the USA and Canada, Latin and Caribbean: Brazil and Colombia), three countries in Europe (the UK, France and Germany) and two countries in Oceania (Australia and New Zealand). Information from the Republic of Korea, USA, UK, Australia and New Zealand was obtained at the national level, and those from the other countries were from one or multiple regional cancer registries. The years of incidence to be collected varied from country to country, but ranged from 1990 to 2014, with the shortest being 12 years (Egypt: 1999–2010, UK: 2000–2011) and the longest being 24 years (Japan and China: both 1990–2013). In this study, we compared the incidence and proportional distribution of subtype in children (0–14 years old) and adolescents (15–19 years old) between these countries.The country-specific age-standardized CNS and miscellaneous intracranial and intraspinal neoplasms incidence rates varied between 3.4 and 39.8 per 1 000 000 person-years in children (0–14 years old) and between 2.2 and 35.7 per 1 000 000 person-years in adolescents (15–19 years old). For children, higher rates were observed in Europe and North America (ranging from 30.8 in the UK to 39.8 in the USA), while rates in Asian and African countries tended to be lower, especially in Uganda with a rate of 3.4 per 1 000 000 person-years. Rates for adolescents were consistently lower than rates for children and followed the same pattern between countries. Figure 1 shows the proportional distribution of subtypes of CNS and miscellaneous intracranial and intraspinal neoplasms in children aged 0–14 years by country. The most frequently identified subtypes were astrocytomas (with proportions ranging from 13.0% in
