The name "Johor" came from the Arabic word "Jauhar", 'gem/precious stone' . Before the name Johor was taken up, the area south of the Muar River to Singapore island was known as "Ujung Tanah" or 'land's end' in Malay, due to its location at the end of the Malay Peninsula. Coincidentally, Johor is the most southerly point of the Asian continental mainland.
