Moriyama Family History
Moriyama Name Meaning
Japanese: usually written 森山 ‘forest mountain’ or 守山 ‘protecting mountain’. The latter version could be taken from any of the three widely scattered placenames in Owari (now part of Aichi prefecture) Iwaki (now part of Fukushima prefecture) or Etchū (now Toyama prefecture). The ‘forest mountain’ version could be taken from even more numerous placenames. Neither version is common as a surname in Japan; they are found mainly in the Ryūkyū Islands.
