Why Japanese can make a run faster
In some games, a player’s progress is held up by text: dialogue must finish appearing, or a message must be dismissed before the next action. Japanese versions can sometimes get through the same exchange sooner because kanji and kana often express an idea in fewer written characters than an English translation. If the game reveals text one character at a time, or splits long passages across message boxes, that can mean fewer frames spent waiting or pressing through dialogue.
The advantage is not simply that Japanese is “shorter.” It comes from how a particular game’s text and timing are implemented. A game might display a whole line at once, impose a fixed pause after each message, or spend far more time on animations and movement than on reading. In those cases, changing languages may save little or nothing.
Runners test the version, not just the language
Speedrunners compare the game’s actual behavior: how quickly text appears, how many boxes an exchange takes, and whether language changes affect other timing. A Japanese release may also differ in wording or presentation, so runners cannot assume that the same route will work identically. For a competitive run, even a small saving can matter—but only if it is repeatable and allowed by that game’s rules.
That is why Japanese is a common choice, not a universal shortcut. The useful question is whether a specific version removes time from a specific bottleneck. When dialogue is the bottleneck, a shorter text sequence can turn a language setting into part of the route.
