Call them his three musketeers. They were not Athos, Porthos and Aramis with weapons of swords and guns but Tokio Hirano, Masahiko Kimura and Takahiko Ishikawa armed with lethal Judo. (...) The third of this trio was Takahiko Ishikawa. In one All Japan Ishikawa and Kimura fought a scoreless match for 25 minutes with both being declared All Japan champions." ;
