What 味千 does

味千ラーメン (Ajisen Ramen) is a Kumamoto-style tonkotsu ramen chain operated by 重光産業株式会社 (Shigemitsu Sangyo Co., Ltd.), a privately held, family-owned Japanese company headquartered in Kikuyo Town, Kumamoto Prefecture. Founded in 1968 as a single 7-tsubo (approximately 23 sqm) shop in Kumamoto, the company has grown to approximately 717 stores across 15+ countries, with ~80 directly operated or identified locations in Japan. The business is structured around three B2C revenue streams — franchise royalties (subscription/recurring), directly operated restaurant sales in Japan (transaction-based), and e-commerce packaged ramen and gift sets sold via the official aji1000.com store and Rakuten marketplace — plus international brand licensing. Pricing for in-store bowls ranges ¥450-800, with online gift sets priced at ¥2,200-3,000 and promotional ramen at ¥390-450 on the monthly '22nd Appreciation Day' (味千感謝デー).

The company's core technology centers on proprietary food production: a '秘伝のタレ' (secret sauce) developed over 50+ years used to braise pork ribs for the signature 'パイクー麺', a burnt garlic oil ('マー油') underlying the '黒マー油ラーメン', and an in-house manufacturing facility in Kikuyo Town producing noodles and retail products. The menu extends beyond ramen into dipping noodles (つけ麺), seasonal chilled tsukemen, and local Kumamoto specialties (Aso takana ramen, red beef gyoza), supported by a multi-brand portfolio including 拉麺 刘, 傳統熊本豚骨 傳, 千のちゃんぽん, 味千食堂, the Ajisen World international concept, and a co-branded joint venture with rival Keika Ramen (味千×桂花).

The company serves a broad horizontal consumer base — from students and young professionals to families and elderly diners — through affordable mass-market ramen, while also selling to gift/omiyage buyers and recruiting individual and corporate franchisees across Japan and internationally. Distribution combines the physical franchise network, the official e-commerce storefront and Rakuten marketplace, department store pop-ups (Takashimaya, Mitsukoshi), and food fair participation. Marketing leverages social media (Instagram, Facebook, YouTube), LINE sticker mascots, television appearances (TV Tokyo 2024, NTV 2022), and a long-running CSR program (味千出前隊, 250+ facility visits since 2008).
