  "commentary": "## 大倉家全株譲渡直後の構成（1957年9月）\n\n1949年6月に大倉家保有株が役員・従業員へ正式譲渡された直後の構成（1957年9月末時点）は、千代田生命1,200,000株・千代田火災海上1,000,000株・富士銀行800,000株・山一証券602,800株・大和銀行500,000株、続いて佐野友二460,000株・都築紡績400,000株・東亜火災海上400,000株・東邦生命340,000株・大倉事業297,000株が上位10名に並ぶ（株式会社年鑑 昭和33年版）。筆頭の千代田生命は1904年に大倉喜八郎が設立した保険会社、大倉事業は大倉家系の持株会社であり、創業家による直接保有が解消したあとも、戦前期から続く大倉系金融機関を介した間接的な資本関係が上位株主のなかに残っていた。\n\n所有者別の区分では個人およびその他が67.0%、金融機関19.6%、その他法人9.8%、証券業者3.6%、株主総数3,642名のうち個人が3,538名を占め、創業家退場後に役員・従業員が株を引き継いだ経緯を反映した個人比率の高い構造が定着していた（株式会社年鑑 昭和33年版）。直近のFY24（2025年3月期）では日本マスタートラスト信託銀行（17.80%）と日本カストディ銀行（5.80%）の信託2行で発行済の23%超を占める信託銀行主導型の構造に変貌しており、大成建設取引先持株会（3.63%）と大成建設社員持株会（2.04%）が戦後譲渡の遺産として依然として上位10位に名を残している。",
