Hardware and software, built by hand.

Across three fields—BMS, flight computers, and RGB laser light-source technology—TEKJP develops everything in-house, from circuit design and embedded firmware to optical design.

Three technologies. Three fields of development.

TEKJP pursues practical, application-driven development across three fields: power management, flight control, and laser light-source technology.

01

BATTERY MANAGEMENT

BMS

Built around semiconductors from Texas Instruments (USA), we develop a fully domestic, Japan-made BMS that spans everything from PCB design to firmware. For drones, eVTOLs, and data center BBUs, we deliver safe power management through high-precision SoC estimation and proprietary firmware.

02

FLIGHT COMPUTER

Flight Computer

We develop a fully domestic, Japan-made flight computer compliant with the Pixhawk V6X standard. Built on the global-standard PX4 OS and U.S. NDAA compliance, and fused with edge AI and our own BMS, it forms the core of industrial drones.

03

RGB LASER

RGB Laser Light-Source Technology

RGB combiner technology that merges the three primary colors of light—red, blue, and green—on a single chip, together with non-diverging beam technology. These hold great promise for new fields of application that will support the society of the future.

Turning technology
into reality with our own hands.

TEKJP is an engineering company that works from both sides—hardware and software—rather than stopping at design alone or implementation alone.
We think through each goal, prototype it, verify it, and refine it into the form it needs to take.Because we are a small team, we value craftsmanship that keeps every detail within reach.

01

Proprietary technology backed by patents

We hold proprietary laser light-source technologies, including our RGB combiner and non-diverging beam technology.Drawing on the expertise we have built up over the years, we also pursue applied development tailored to each use case.

02

A track record of mass production and shipment

Our BMS charge-control boards are shipped to North American companies in the B2B sector. Through repeated cycles of design, manufacturing, verification, and refinement, we build quality that holds up in real-world operation.

03

Technical challenges that aim higher

We are developing technology built to meet the demands of the next generation of applications—higher voltages, more stable control, and more compact, easier-to-handle configurations.

We're looking for people to build with us

We are hiring engineers who bring depth in a specialized field—circuit design, embedded software, power control, data control—while also being willing to step into adjacent areas. If you want to build things that actually work with your own hands, from design through implementation to verification, we'd love to talk with you.
