What BH does

BH Inc. (BH株式会社) is a Tokyo-based private IoT software and hardware company founded in October 2014 that builds wireless remote-control and automation products for industrial facility management and digital transformation (DX). Its portfolio centers on a proprietary LoRa wireless platform operating in Japan's 920MHz band, headlined by Field Magic — a controller system that pairs with relay-output, digital I/O, and analog-input units to monitor and control distributed equipment over line-of-sight ranges of approximately 5km, extendable to ~10km via three-hop relay, with visualization through a Map App and standard apps running on Node-RED, Grafana, and PostgreSQL. Surrounding products include the Area Operation Lighting System (FREETE), co-developed and jointly patented with Toyota Motor Corporation; AirRain Eco (smart urban-greening irrigation, Good Design Award 2025) and AirRain Turf (golf-course/farm irrigation); SMARTIO, a 4-in/4-out remote I/O device; and Smart Reporter, a wireless sensor monitoring cloud service with WebAPI integration.

The company sells predominantly through a direct, sales-led enterprise motion via website inquiry and phone (03-6407-1866), supported by industry exhibitions (Green Factory EXPO) and a distributor relationship with Harada Sangyo Co., Ltd. for FREETE. Hardware SKUs are priced on a one-time / perpetual-license basis (e.g., 238,000 JPY trial kits ex-tax), while AirRain Turf requires a monthly cloud subscription — making BH's revenue model a mix of upfront hardware revenue and limited recurring software. Customer use cases span factory lighting/HVAC/ventilation control, construction-site temporary power and lighting, golf-course irrigation, urban green space management, and disaster-prevention monitoring (water levels, flood, manhole). The company operates with 1-10 employees, has not disclosed any external funding rounds, and is led by Representative Director Sawa Norihito.
