What Sakai does
Sakai Holdings Co., Ltd. (株式会社サカイホールディングス) is a Nagoya-headquartered, publicly listed Japanese holding company founded in 1991, operating four wholly owned subsidiaries across five business segments. Its core revenue line is the Mobile Communications Agency business, operated through SKI Inc. (株式会社エスケーアイ), which runs SoftBank-branded retail shops nationwide and has held the #1 overall ranking at SoftBank's national owner meetings for 7 consecutive terms. The group also sells life and casualty insurance through Central Partners (株式会社セントラルパートナーズ), operates funeral halls under the Tear brand via SKI Management (エスケーアイマネージメント株式会社), and conducts real estate leasing and management through SKI Development (エスケーアイ開発株式会社).
In November 2013, Sakai entered the renewable energy business and now operates 49.4 MW of solar power generation capacity across Japan, selling electricity to power companies under Japan's feed-in tariff (FIT) framework. Sakai also operates restaurant locations under the Omuraisu-tei chain (e.g., Rinku Premium Outlet) and has a partnership with JTB Corporation for an SDG Evangelist certification e-learning product. The group employs ~559 people across its five group companies as of September 2025 and is led by Representative Director and President Asahata Koji (朝田 康二郎).
The business model blends high-volume transactional/commission revenue (SoftBank agency sales, insurance commissions) with recurring regulated revenue (FIT solar) and direct-to-consumer services (funeral halls, restaurants, real estate). Distribution is overwhelmingly domestic Japan, primarily through physical retail storefronts in shopping centers and direct field sales. Revenue in fiscal 2025 was approximately 115 billion JPY (~USD 767M at ~150 JPY/USD), recovering from a 2022 trough. The company has disclosed active shareholder return policies and faces regulatory headwinds, including a 2024 surcharge payment order from the Financial Services Agency following a Securities and Exchange Surveillance Commission recommendation.
