FACTORY development team is kicking off a writing festival 🎉

I'm Mizuno from the KINTO FACTORY development group.

Hello to those meeting me for the first time—and to those who already know me.
My name is Mizuno and I am the group manager of the KINTO FACTORY development group.
I usually work as the group manager for the KINTO FACTORY development group, and also take on other product management and progress management roles. Lately, I've been into growing vegetables in my garden.

What is the KINTO FACTORY Development Group?

The KINTO FACTORY Development Group is a team formed to launch and continuously improve the KINTO FACTORY e-commerce site . The upgrade business for genuine manufacturer parts for Toyota, Lexus, and GR vehicles, which started as a proof of concept about three years ago, was moved into full production two years ago through in-house development and a complete site renewal. Since then, we have continued to add products and improve our e-commerce site.

Currently, we operate as follows:

• Number of members: 12 (as of August 2025)
• Main roles: Product manager, web director, frontend engineer, backend engineer, QA engineer
• Team atmosphere: Open and flexible. If something sparks our interest, we dive in. We work together to fulfill requests.

Product Introduction

KINTO FACTORY is a service that allows you to "evolve" your vehicles after purchase. You can update your vehicles. What's more, you can enjoy a customization experience by applying online and receiving a PDF certificate that verifies your vehicle upgrade. Since the service name includes KINTO, it's easy to mistakenly think that this only applies to KINTO vehicles, but it actually applies to any TOYOTA or LEXUS vehicle you own.

There are three main service categories:

• Upgrades : Add safety features and comfort functions after purchase. For example, "smooth braking" and "parking support brake."
• Modification : Refresh the interior and exterior. Replacing the seats and steering wheel will give you a new feel.
• Personalization : Use driving data to tailor your car to better suit your individual style and needs.

From a technical point of view, it should be quite interesting as it runs on a microservice architecture on AWS behind the scenes, and the upgrade certificates (limited to products for which upgrades have been carried out) are issued digitally. If you're curious to know what kind of engineers are behind the system, be sure to check out the interviews below and our upcoming blog posts!

Now, we've come to the main topic of this post. It's short.
The KINTO FACTORY development group has decided to hold the summer tech blog writing festival from August through September!

• Explain what KINTO FACTORY is.
• Share technical knowledge.
• Communicate the team atmosphere.
• Increase contact with various people.
• Increase the number of team members who share the same goals.

We will start by letting people know about the team members behind KINTO FACTORY through this tech blog.
