Mahoroba is an ancient japanese word describing a far-off land full of bliss and peace. It is roughly comparable to the western concepts of arcadia, a place surrounded by mountains full of harmony and quiet.

Mahoroba is only written in hiragana as まほろば. The origins of the word are not clear, it is described in a poem in the ancient Kojiki (古事記) as being the perfect place in the mythical country of Yamato:

Yamato ha

Kuni no mahoroba

Tatanatsuku

Awo-kaki yama-gomoreru

Yamato shi uruhashi

The Space Battleship Yamato had a sister-ship that was named Chou Jikuu Senkan Mahoroba (The Ultimate Time Sweeper Mahoroba)
