We have developed a portable enterprise communication system that allows multiple users to talk simultaneously. 

Our company applies extensive digital wireless technologies to plan, develop, manufacture, and sell a range of products including low-delay wireless digital modules. We also offer digital wireless guide systems, digital wireless intercoms, handy speakers (smartphone output for TV sound), wireless LED control systems, and wireless LED color mixing systems. Our technology allows us to offer contract development and contract manufacturing services. Another characteristic of our company is that these products can be provided at low cost.

Sales Pitch

Low-delay wireless audio module 2.4GHz/5GHz
Our 2.4GHz digital wireless module has achieved the industry’s shortest delay, at 0.6 ms.
The 5GHz digital module has reduced the delay to less than 1 ms.
The sound quality is high because of digital processing. This product is applicable to wireless headphones and microphones of musical instruments and game devices where a delay is a bottleneck.
Our company takes complete action against interference. We compensate for missing data by two-wave simultaneous transmission and reception to avoid interference.
Consignment development and manufacturing based on digital wireless technology
Consignment development (mechanical design, circuit design, PCB design, firmware design, PC application design, smartphone application design, etc.)
Consignment manufacturing (from molding to part purchase, PCB manufacturing, main unit assembly, packaging material design and production, label design and production, inspection jig design and production, manufacturing process design, etc.)
Our group member company RONK Shanghai designs and manufactures products and provides them at low prices to satisfy the needs of Japanese customers. Our digital wireless products developed on the basis of needs are adopted by major companies, and their technical superiority is highly regarded.
Digital wireless intercom system
Our portable intercom does not require a base station. Setting one of the cordless handsets as the master enables two-way conversations simultaneously among four people. The system can be installed at a reasonable price because a base station is unnecessary.
Our intercom with base station allows two-way conversation among up to six people per base station. If the base station is expanded, up to 30 people can have two-way conversations. You can add an unlimited number of listening-only handset units.
You can use our product under any environment, such as a narrative earphone microphone, closed headset microphone, open headset microphone, and bone-conduction earphone microphone. We are ready to customize our products. Feel free to consult us.
Wireless guide system
The wireless guide (ear guide) adopted for the New Kabukiza Theater has an ultra-lightweight and ultra-compact design featuring noise cutting, clear sound, and no interception or interference.
The receiver is ultra-lightweight and ultra-compact, so it can be used like an ID card without feeling any stress.
This product is also used as a simultaneous interpretation system and can be customized to  customer needs.

[Representative's message]
Our company has worked with our subsidiary Ronk Shanghai since our establishment to separate the design and manufacturing processes of digital wireless devices from sales activities targeting the Japanese market. We try to evaluate quality and availability for individual materials and components in the design phase as well as enhance efficiency in terms of cost and delivery. We do this to faithfully satisfy customer needs. We sincerely hope that J-GoodTech will bring new customers who need the originality and advantages of our technologies. This includes our low-delay wireless modules, digital wireless guide systems, and digital wireless intercoms. 



[Company structure for market development/overseas expansion]
We have received sales support from the Sagamihara Incubation Center since our establishment because our office is housed in its building. We plan to participate in more exhibitions such as Wireless Japan to increase exchanges and opportunities in various industries for sales channel expansion. We can conduct business in Chinese and English, so we want to pursue potential customers in other countries.
