The company delivers end-to-end ("一気通貫") enterprise IT services — consulting, design, development, implementation, and ongoing operations/maintenance — through eight solution lines targeting large life insurance companies, manufacturers, logistics operators, rental/leasing firms, and cross-industry DX initiatives (insurance, manufacturing, logistics, rental, low-code/Power Platform, PC kitting, IoT, and cloud infrastructure). Its deepest domain expertise is in life insurance core systems, built over more than two decades.

The firm also operates a proprietary IIoT product portfolio under the iBRESS brand (Industrial BellChild Remote-location Executive System Service), developed through the Kansai-based Thundercloud Project. Products include DataHub middleware (distributed as master distributor for Skkynet Cloud Systems of Canada), iBRESS Cloud (secure non-VPN data transmission), PUERTO UA Monitor/Recorder/ClientCore (OPC UA Excel add-on and client modules, sourced from wholly-owned subsidiary Puerto), MT System (multivariate Mahalanobis-distance anomaly detection, licensed from Mitsubishi Heavy Industries), and OWCD (one-way data diode security, also MHI-licensed). It is an AWS Partner Network Technology Partner and an OPC Foundation Logo Member.

Revenue is generated primarily through professional services (system integration engagements) supplemented by product resale and licensing (Skkynet, MHI-patented, Puerto). The company employs 225 staff (266 with group companies Vantec and Puerto) and operates offices in Osaka (HQ), Tokyo (Hamamatsu-cho HQ + Kamata satellite), and Sendai. FY revenue is disclosed at ¥3.2 billion. Distribution is exclusively direct enterprise field sales with no channel partners, and the firm holds ISO 27001, Privacy Mark, Kurumin, and Women's Active Participation certifications.

Core offering

BellChild delivers end-to-end IT system integration services — consulting, design, development, implementation, and ongoing operations/maintenance (一気通貫) — for mission-critical enterprise systems in insurance, manufacturing, logistics, and rental/leasing industries, plus cloud migration (AWS/Azure/GCP) and low-code (Microsoft Power Platform) solutions. Alongside services, BellChild sells and distributes its proprietary iBRESS IoT/IIoT product suite including DataHub middleware, iBRESS Cloud secure data transmission, PUERTO OPC UA products, MT System predictive maintenance, and OWCD one-way data diode, as the Japanese master distributor for Skkynet Cloud Systems.

Product overview

BellChild offers a portfolio of IoT/IIoT products and enterprise IT solutions organized around two main pillars. The iBRESS suite is BellChild's core IoT platform — a collection of middleware and services that includes DataHub (Skkynet-sourced middleware for device-to-cloud connectivity), iBRESS Cloud (secure non-VPN data transmission), PUERTO UA Monitor/Recorder/ClientCore (OPC UA Excel add-on and client modules for industrial data acquisition), MT System (multivariate anomaly detection for predictive maintenance, patented by MHI), and OWCD (unidirectional data diode for network security, also MHI-patented). DZ Security adds biometric authentication. Complementing the IoT products are eight enterprise solution services: Insurance, Manufacturing, Logistics, Rental, Low-Code (Power Platform), PC Kitting, Cloud Infrastructure, and IoT Solutions. BellChild is also a master distributor of Skkynet products and resells MHI and Puerto products in Japan.
