What Nakayo does

Nakayo Co., Ltd. (株式会社ナカヨ) is a Japanese telecommunications equipment manufacturer founded in 1944 in Setagaya, Tokyo, originally as Chūyo Communications Equipment Manufacturing, renamed in 1974. The company designs, manufactures, and sells business telephone systems (the NYC-X, NYC-Si, and NYC-2S IP PBX series), single-line design phones (Simor neo / NS-R01), intercom systems for residential buildings, healthcare and nursing-care communication systems (Care NYC emergency call, NYC Hikari), IoT sensing platforms (Building NYC, Micro Server), security products, and HVAC/air-quality devices, holding ISO 9001, 14001, and 27001 certifications plus a medical device manufacturing license. Core technology centers on-premises IP telephony, edge sensing hardware, and dealer-managed installation and lifecycle services.

Nakayo sells exclusively through a nationwide authorized dealer network called 'Nakayo Kai' (ナカヨ会), spanning Hokkaido, Tohoku, Kanto, Chubu, Kansai, Chugoku, Shikoku, and Kyushu, with pricing quote-based through dealers rather than publicly disclosed. Revenue is generated across three streams: hardware sales (business phones, intercoms, IoT devices), subscription/recurring services (Nakayo Hikari optical fiber, communication solutions), and Electronics Manufacturing Services (EMS) contract manufacturing. Primary customer segments are Japanese small and medium businesses, with secondary exposure to healthcare and nursing facilities, residential building operators, manufacturing plants, and hospitality venues. The company employs 501-1,000 people and operates from headquarters in Maebashi, Gunma (relocated from Tokyo in 2009), with additional offices in Tokyo and Hong Kong.

Nakayo was listed on the Tokyo Stock Exchange (ticker 6715) from 1974, with a First Section listing from 2005, and was delisted in 2025 when it became a wholly-owned subsidiary of Ai Holdings Corporation, ending 51 years of independent public company status. This acquisition followed a multi-year period of revenue contraction and negative EBITDA in 2023-2024, reflecting structural pressure on legacy Japanese business telephony hardware amid mobile substitution and cloud PBX competition.
