Our Development Process
Discovery & Proposal
A Japanese-speaking PM/BrSE serves as your main contact and carefully supports requirements clarification and project management.
Offshore development helps reduce software development costs by building with teams in countries such as Vietnam, where engineering costs are more competitive. Many companies now use offshore teams directly or through development partners.
System Design
Offshore cost efficiency with enterprise-grade quality.
We continuously follow the latest technology trends and propose practical, modern solutions to our clients.
Development & Maintenance
Over eight years operating our own services and supporting long-term product growth.
We are not limited to frontend, backend, or mobile app development. KaiyouIT can handle the entire development process in one integrated team.

FAQ
FAQ
- What is the process before ordering?
- After you contact us through the form, we will review your request and schedule a discovery meeting.
We then prepare an estimate. Once the terms are agreed, we move to contract, development, and delivery. - What is the difference between fixed-scope and lab-style development?
- Fixed-scope development is similar to waterfall development and usually requires specifications, wireframes, or design files for estimation.
Lab-style development is a time-based quasi-mandate model. The minimum term is three months, with a minimum order volume of two person-months per month. - Can you develop iPhone and Android apps?
- Yes. Mobile app development is one of our strengths. For higher-budget projects, we recommend Swift for iOS and Kotlin for Android.
If cost efficiency is important, we recommend cross-platform development, especially Flutter. - Can we communicate entirely in Japanese?
- Yes. You can work with us entirely in Japanese. Our Japanese-speaking members support communication throughout the project.
