Who we are
Supporting the digitalization of small businesses, through real operations.
3WB is not a company that simply sells systems. We start from how our clients actually work: we understand the business, organize the flow, and then design the processes and systems it needs.
And we don’t stop at delivery. We stay with you through day-to-day operation.
We support the operations and digitalization of small and mid-sized businesses, from the ground up.
Our business
Three business areas
Technology, operations and business support, delivered by one team.
-
TECHNOLOGY
System development & DX support
We sort out the real operational issues a company faces, then design and build the systems and digital environment it needs.
-
OPERATION
Digital bookkeeping & back-office support
We turn daily work such as bookkeeping, invoicing and payroll into data, and make it more efficient by combining our own systems with hands-on operations.
-
BUSINESS SUPPORT
Japan market entry & business management support
For foreign companies and business owners operating in Japan, we support the back office, IT and operational setup after the company is established.

Our approach
DX that starts on the ground
Installing a system is not the goal. What matters is understanding the work and turning it into a more efficient process.
- 01 BUSINESSUnderstand the actual work
- 02 ISSUESort out problems and inefficiencies
- 03 DESIGNDesign the business process
- 04 SYSTEMBuild the process into a system
- 05 OPERATIONRun it in real operations
- 06 IMPROVEMENTKeep improving based on data
After improvement, we return to understanding the work again.

Technology follows Business.
We start from the business, not from the technology.
Products
Systems born from our own operations
We built these systems to solve problems we found in our own daily work, and keep improving them as we use them in-house.
