尻取り

The word shiritori breaks into two parts: shiri (尻), meaning the rear end or tail, and tori (取り), meaning taking or grabbing, from the verb toru. The name describes exactly what the game requires: grab the tail of the previous word and start fresh from it. If the previous player says sakura, you must begin with ra. The game ends when someone says a word ending in ん, the one mora in Japanese that has no valid successor.

Word-chain games appear in Heian court literature of the 11th century, and a form resembling shiritori circulated among aristocrats who competed on breadth of classical vocabulary. The specific name shiritori was established by the Edo period, when it spread among merchants, students, and travelers who needed no equipment and no common ground beyond shared vocabulary. Schools adopted it as a vocabulary exercise; children played it because the ん-ending felt like losing a bet.

Shiritori is harder than it looks. Japanese phonology consists almost entirely of open syllables, so the chain can continue almost indefinitely. The constraint is vocabulary, not phonology. Advanced players avoid words ending in り (ri) because ri-words are common and the chain spirals through them rapidly, and they maneuver opponents toward words with few valid successors.

The game traveled into Japanese pop culture through television variety shows, anime, and mobile apps. The 2012 anime series Jinrui wa Suitai Shimashita uses shiritori as a survival mechanism, and NHK has broadcast shiritori competitions. App versions log millions of word submissions. It is now a cultural export, taught to Japanese-language learners worldwide as one of the first games they can play.
