SYSTEM DEVELOPMENT & DX PARTNER

Your challenges are now solvable.

Advances in AI have opened paths to challenges that once seemed out of reach. From custom business-system development to AI-powered process improvement and building the capability to keep developing in-house, we support you from planning through operation.

Do any of these sound familiar?

Maintaining and updating an aging business system has become a burden
Development is fully outsourced, and no know-how stays in-house
You want to use AI and digital technologies, but don’t know where to start

Yokatai’s “development plus in-house enablement” approach solves these problems.

When system development or AI adoption fails, the cause is rarely the technology itself. More often, no one has designed where — and how — it fits into the actual work. Even an excellent tool never takes hold if it stays disconnected from existing workflows.

We start by mapping your operations and clarifying the real problems, identify where technology can genuinely help, and then build systems that fit into the way you work. After launch, we help you build the capability to operate and improve them with your own team.

From judging what the technology is good for, to keeping it working for you — covering that whole journey is what sets us apart.

What we offer

Start small, verify, then move forward

We turn ideas into working prototypes in a short time, so you can confirm real behavior as development proceeds. This prevents the classic “it wasn’t what we expected” failure and lets you make investment decisions step by step.

One partner from planning through operation

Problem framing, design, development, and post-launch operation and improvement — all through a single point of contact. From evaluating the technology to keeping it in productive use, you can leave the whole journey to us.

Services

Custom System Development

We build systems tailored to your specific challenges — from planning and new development of business systems and web applications to enhancing and operating existing systems, covering the full lifecycle end to end.

AI Adoption & DX

We embed generative AI and cloud technology into your operations to improve efficiency and create new services. Beyond simple chat-style Q&A, we specialize in AI agent technology that works autonomously over extended periods.

In-House Enablement & Training

Instead of leaving development and operations to outside vendors, we help you build a team that can operate and improve systems internally — from introducing generative AI into daily work and development processes to training your people, at a pace that fits your organization.

About us

Yokatai Inc. is a software development company centered on custom system development, extending into AI adoption, digital transformation, and in-house enablement — helping clients build the capability to keep developing on their own.

From operating large-scale infrastructure to applying the latest generative AI, we bring hands-on engineering experience to deliver systems that reliably work. From requirements through design, development, and continuous improvement, we support you through a single point of contact.

Company profile

Message from the founder

I have spent many years as an engineer in system development. Along the way I encountered the evolution of generative AI, and it feels unlike any technology that came before. It would be a waste to keep your distance just because it seems difficult. I founded Yokatai out of a desire to make this technology something anyone can use with confidence.

Even if your question is still at the “could software or AI do something like this?” stage, we would love to hear it. Please feel free to reach out.
