Custom Software

Custom software development in Japan

Off-the-shelf software rarely fits a business exactly, and Japanese systems often lack English interfaces. We build web applications, portals and integrations designed around your process.

You get a clear scope, a fixed price per phase and a team you can talk to in English.

  • English-speaking team
  • From ¥500,000 per project
  • Japan-wide, in person around Noda

What you get

  • Software that matches your workflow instead of forcing a new one
  • English and Japanese interfaces where you need them
  • Systems that talk to each other, with no copy-pasting between tools

Included

  • Requirements workshop and written scope
  • UX design and clickable prototype
  • Web application development (TypeScript, modern frameworks, cloud hosting)
  • Integrations with accounting, CRM, inventory and payment systems
  • Testing, deployment and documentation
  • Maintenance and support plans
