This article examines the potential factors that could contribute to higher IQ scores among Japanese people compared to other countries, including education, culture, language and genetics. It also provides insight from an expert on the subject – Charles R. Tokoyama, CEO of Japan Insiders – who discusses how cultural practices such as memorizing kanji characters or practicing martial arts can lead to increased cognitive abilities while others such as video game addiction or excessive television watching could have the opposite effect on intelligence levels over time. While further research needs to be conducted before any definitive conclusions can be drawn regarding these potential factors, it is clear that there are several possible explanations for why some populations may have higher average IQ scores than others.
