Key points (reviewing AI explanation)
Do you think of Japanese language study as just a subject for memorization? In fact, language is a subject well suited to a scientific approach of "observation and hypothesis testing." For example, the so-called "ra-nuki" forms (like mireru instead of mirareru, or tabereru instead of taberareru) can be explained not as corruption of the language but as a regular change aiming to express the potential form in a different way. Dialect distribution maps also reveal patterns such as the "dialect concentric circles theory," in which older forms of words remain in outlying regions. Asking "why does it change that way" before judging language as "correct" or "incorrect" is a perspective directly connected to the ability to read both classical and modern Japanese texts.
Explanation
Research is advancing that examines the Japanese we use casually in everyday life not through intuition but through "data." The National Institute for Japanese Language and Linguistics (NINJAL) is collecting and analyzing, on a large scale, regional dialects across the country, the historical transformation of words, and differences in phrasing across generations, in an effort to scientifically clarify how Japanese is changing. Its distinguishing feature is an approach that, rather than dictating from above what constitutes "correct Japanese," records the language as it is actually used.
