A figurative expression database was constructed based on the Balanced Corpus of Contemporary Written Japanese (BCCWJ), with the goal of understanding actual usage of figurative expressions in Japanese.

Examples were also classified into categories such as synecdoche, metonymy, contextual metaphor, and idiomatic expression. Although the work above was carried out by linguists, ratings were also assigned to each example for five aspects (figurativeness, novelty, comprehensibility, personification, and substantiation) based on evaluations by twenty two to seventy seven non-experts (average: thirty three) to evaluate how these figurative expressions were perceived. The usage trends for each of these figurative expression indicators in contemporary Japanese were determined based on their relative frequency in each register and distribution of their rating values.
