Easiest first. “Words to 70%” is the size of the vocabulary that covers 70% of all dialogue; see methodology.

What makes a film easy or hard

Two things separate My Neighbor Totoro's 155 words from Porco Rosso's 373: how much vocabulary a film uses, and how much it reuses it. A film about daily life keeps returning to the same words (meals, school), so each word you learn pays for many lines. A film that ranges over war and spirits spreads its dialogue across far more words, and each one buys you less.

Length matters less than you would guess. What matters is dialogue density and range: quiet films with long wordless stretches sit near the top of the table almost regardless of runtime.

One vocabulary for the whole catalogue

Films share their everyday words, so the catalogue costs far less than the sum of its parts. Adding films in the cheapest order, all 17 Ghibli films reach 70% on 2,030 words. The first film is the expensive one; the last adds just 158 words you don't already know.

1,0152,0300films added, cheapest next film first
Cumulative vocabulary for 70% of every film added so far. Each dot is one film; the flatter the curve gets, the more the words you already know carry the next film.

Include the Kurosawa films and the whole catalogue reaches 70% on 2,877 words. Twenty-six films, one shared vocabulary.

Which one should you start with?

Not automatically the easiest: the film you want to understand is the one you will stay with. Still, the data gives defaults. My Neighbor Totoro for gentle family Japanese near the top of the ranking, Kiki's Delivery Service for everyday Japanese. If Spirited Away is the film that made you want to learn in the first place, start there.

The Kurosawa table

Nobody teaches Japanese through Kurosawa, so we did the same analysis for 9 of his films. Rashomon needs only 155 words to 70%, the smallest of any film in our catalogue, Ghibli included: one story told four times reuses its own vocabulary relentlessly. The full case: learning Japanese with Kurosawa.

Methodology

For each film we analyze the full Japanese subtitle track with a morphological parser and reduce every word to its dictionary form, dropping pure grammar (particles, auxiliaries) that no one studies as vocabulary. “Unique words” counts the distinct content words that remain; “lines” is the subtitle cue count we analyzed.

“Words to 70%” walks the film's words from most to least frequent, adding words until they cover 70% of everything said. It is the same computation Katarineko uses to build a learner's curriculum, run against an empty vocabulary. The ranking you see here is the plan the product would hand a beginner. We publish the number rather than an invented difficulty score: you can recompute it from any subtitle file.
