If you're talking about the Eternal Ring, it's just set to 'always run' in the US/EU versions.The slow movement speed in King's Field is a design choice, because that way they don't have to use loading screens and can make one gigantic, seamless dungeon. The FPP crawlers by From that have loading screens have noticeably faster movement speeds.
It's not just the running speed that's faster in Eternal Ring, but you turn faster as well.
