Ogiya Group

What Ogiya Group does

Ogiya Group is a privately-held, family-controlled diversified service conglomerate headquartered in Toyohashi, Aichi Prefecture, Japan, founded in 1946 by Toshio Ooki and incorporated in 1950 as Ookiya Co., Ltd. The group operates five distinct business verticals through 7 related subsidiaries and 709 total employees (as of January 2026): (1) OGIYA-branded pachinko and slot amusement halls (17+ locations across Aichi, Shizuoka, Nagano, Gifu, Shiga, and Hyogo prefectures) — the core revenue driver; (2) Spaghettì-tei Chiao, an Italian-style spaghetti restaurant chain (6 locations: 3 directly operated and 3 franchise, celebrating its 60th anniversary in April 2025); (3) Harbor View, a single 64-tee golf driving range with body care salon and golf school in Toyohashi; (4) Machi no Oasis, a dementia-care group home / small-scale multifunctional home care operation with 4 facilities in Toyohashi and Anjo; and (5) Ooki Development, a real estate development subsidiary.

Revenue mechanics are predominantly transaction-based at point-of-sale in physical retail storefronts, supplemented by recurring annual memberships and golf lesson subscriptions at Harbor View, and managed-services compensation in the healthcare segment. Distribution is regional and physical-retail-led, with limited e-commerce (restaurant product sales via Rakuten) and a franchise channel for select restaurant locations. The company runs a direct-to-consumer go-to-market model with corporate recruitment supporting cross-division staffing.

Leadership is held by the Ooki family across generations: founder Toshio Ooki (1946), Chairman Masayoshi Ooki, and current Representative Director/President Nobuhiro Ooki (in role since 2001). The group holds no external institutional investment and is entirely family-controlled. There is no proprietary technology platform disclosed; operations are service-based with consumer-facing digital channels limited to brand websites, Instagram, LINE, a restaurant mobile app, and Rakuten storefront.

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Skylark Group: Operates multiple Japanese casual dining chains. Comparable as a multi-brand restaurant operator with franchise and company-operated formats serving regional Japanese consumers, similar to Spaghettì-tei Chiao's mixed model.
• Nichii Gakkan: Major Japanese operator of nursing care, group homes, and healthcare staffing services. Comparable to Ogiya's Machi no Oasis elderly/dementia care division as a residential care provider, but at national scale with broader medical and educational services.
• Sompo Care (Sompo Holdings): Operates a nationwide network of group homes, assisted living, and senior residences in Japan. Directly comparable care model to Machi no Oasis's group home operations, but with national distribution and corporate parent backing.

Direct peers

• Round One Corporation: Operates entertainment centers combining bowling, karaoke, sports, and amusement arcades across Japan and internationally. Comparable to Ogiya's amusement division as a multi-format indoor entertainment facility operator serving regional consumer bases.
• Saizeriya: Operates a large casual Italian restaurant chain in Japan with a similar value-priced pasta-focused menu and family dining positioning. Most directly comparable peer to Spaghettì-tei Chiao on price point and category, though at vastly greater scale.
• Fields Corporation: Pachinko hall operator and content/IP distributor in Japan. Comparable as a vertically integrated pachinko entertainment company operating physical amusement facilities across multiple regions.
• Nippon Leisure Development: Japanese operator of golf practice ranges and leisure facilities. Comparable to Ogiya's Harbor View driving range business as a regional golf practice and recreation operator.
• Universal Entertainment: Pachinko/pachislot machine maker and operator of pachinko halls. Comparable vertical overlap with Ogiya's core amusement business, though Universal is more manufacturing-weighted.
• Heiwa Corporation: Japan's largest pachinko machine manufacturer and pachinko hall operator. Directly comparable to Ogiya's 17+ OGIYA-branded pachinko halls as a multi-region amusement operator, though Heiwa is significantly larger and publicly listed.

Regional players

• Tokyu Recreation: Operates golf courses, ski resorts, and leisure facilities primarily in the Tokyo metropolitan and Kanto regions. Comparable recreation/leisure model to Ogiya's Harbor View, though serving a different geographic market than the Aichi/Tokai focus.
