Sci-Fi & Space

Word frequency is counted across 10,184 subtitle lines classified into this genre from JESC, an open research corpus of 2.8 million Japanese TV & film subtitle lines (Pryzant et al. 2018, CC BY-SA 4.0).

The map only lists words that already have a reviewed entry in our library — a frequent word you expect may still be in production, and each new set extends the map.

A few entries are compound words counted under their core component (a student-council compound under its base word, for example), so a count can occasionally sit slightly above the entry ranked before it.

Counts tied to specific franchise titles are excluded or adjusted, and the corpus predates 2018 — so the newest slang of a genre can rank lower than it feels like it should.
