一万(いちまん)

Note that the 一(いち) is required: just "万(まん)" alone is not used as a number on its own (unlike English "thousand," which can stand alone as a quantity).

Usage

Larger numbers in Japanese are grouped by ten-thousands rather than thousands, so reading large figures often requires re-parsing. For example, 250,000 is 二十五万(にじゅうごまん), not 二百五十千(にひゃくごじゅっせん).
