Zusammenfassung:The aim of this study was to identify the cognitive structures of kanji abilities in the Japanese general population and to examine age and cohort effects on them. From a large database of the most popular kanji exam in Japan, we analyzed high school graduation level data of 33,659 people in 2006 and 16,971 people in 2016. Confirmatory factor analyses validated the three-dimensional model of kanji abilities, including factors of reading, writing and semantic comprehension. Furthermore, the age effect on writing, and correlations between writing and semantic dimensions, were different between 2006 and 2016, suggesting reduced writing ability and stagnation in integrated mastery of kanji orthography and semantics in current-day Japanese adults. These findings provide the first evidence of the multidimensional nature of Japanese kanji abilities, and age/cohort differences in that dimensional structure. The importance of the habit of handwriting for literacy acquisition is discussed.
