Take your service to the next level with AI Take your service to the next level with AI

We use AI to streamline tasks such as customer inquiries, document creation, image checking, data analysis, information organization, and decision support that are still being done manually, helping to improve your service and reduce workload.

We handle everything from adding AI features to existing systems to developing brand-new AI services.

  • Streamline your internal systems

    We develop and improve web systems tailored to your daily operations, including attendance, inventory, customer management, delivery management, document output, and admin dashboards.

  • Launch your own service

    We bring new services to life, such as booking sites, matching services, membership sites, and Shopify (e-commerce) stores.

About us

The development environment for AI, web systems, and mobile apps is evolving every day.

We have been involved in a wide range of development projects for over twenty years.

Building on the experience we have gained over the years, we actively adopt new technologies to develop systems that are easy to use and easy to maintain.

From website production and web system development to mobile app development and AI-powered feature additions, we propose the best solution for each client's goals.

At Makoto Tejima, we take every inquiry seriously and put our full effort into each project, one at a time.

Difficulty

Do you feel that system development is difficult?

Many people who come to us for consultation say things like "we lost contact with our developer" or "the system we got wasn't what we expected."

Having worked in this industry for a long time, the solution is simple: align understanding in meetings and put it in writing as documentation (specifications).

This is standard practice in other industries, but in the IT industry this step is very often skipped. Doing this step properly improves the following:

AI can support the creation of that documentation, as well as the development work that follows.

Lack of communication

Misunderstandings and missed information lead to trouble and rework.

AI Assist AI automatically organizes meeting notes and key points to prevent misunderstandings.

The system turns out different than expected

After completion, clients often find "this isn't what I imagined," leading to extra costs and delays.

AI Assist AI visualizes and compares requirements, helping catch discrepancies early.

That's why we create documentation

Clarifying requirements and specifications in documentation helps align understanding and stabilize quality.

AI Assist AI supports documentation creation, improving both quality and efficiency.

Process

Flow

  1. Meeting

    We start with a meeting to understand your needs, and will propose ideas ourselves if needed.

    Supported by AI assistant

    AI analyzes the meeting notes to help organize challenges and suggest the best direction for our proposal.

  2. Contract

    Once the requirements have taken shape through discussion, we sign a contract.

    Supported by AI assistant

    AI checks the contract contents to help detect risks and confirm unclear points.

  3. Design

    While listening to your requirements, we create the specifications that serve as the blueprint for the system.

    Supported by AI assistant

    AI organizes requirements and helps check for gaps in the design and suggest the optimal structure.

  4. Development

    We develop the design and system accordingly, making adjustments along the way if you have further requests.

    Supported by AI assistant

    AI visualizes development progress, supporting quality checks and more efficient code review.

  5. Delivery

    After you review the completed work and we make any necessary adjustments, we deliver the final product.

    Supported by AI assistant

    AI automatically organizes test results and documentation, streamlining the delivery process.
