孝心館 is the title for Koushinkan, Koshinkan, or Kōshin-Kan.
The romanization of this title varies a little, but the original characters are the same.
孝 = Filial piety or obedience.
心 = Heart, mind, intention, or center.
馆 = Building or establishment (dojo).
This can be pronounced in Chinese and has the same meaning, but you should consider this a Japanese martial arts title.
