「万」(man) means "ten thousand" or "10,000". This is a very important unit in Japanese, as numbers are grouped in sets of four digits (e.g., thousands, ten thousands), unlike the Western system where they are grouped in threes. Example: 「一万円」(ichi-man-en) means "ten thousand yen".

「万」（まん）は「10,000」を意味します。日本の大きな数の数え方で、とても重要です。例：「一万円」（いちまんえん）。
