A hackathon for modifying mini 4WDs - Speed is justice!! Hack the mini 4WDs with precision machining technologies -

Closed FRI, JUL 21, 2017 - THU, AUG 10, 2017

Hack Mini 4WD with precision processing technology in Suwa City, Nagano Prefecture!

Suwa City, Nagano Prefecture, where manufacturing companies with the highest precision processing technology in Japan are concentrated. Utilizing this technology, we will hold a tour & hackathon "SUWACKATHON" to create a special "Mini 4WD".

We are currently looking for creators to join SUWACKATHON. Cut, bend and polish your own mini 4WD with ultra-fine processing technology in micron units to create an innovative mini 4WD!

What are you doing?

SUWACKATHON participants will participate in a tour to Suwa City, Nagano Prefecture, and the Mini 4WD Hackathon in Tokyo by the following process.

Step 1: Factory tour and matching tour in Suwa City, Nagano Prefecture

On August 18th (Friday) to August 19th (Saturday), we visited 7 companies' factories with precision processing technology in Suwa City, Nagano Prefecture by bus tour. During the tour, matching will be performed to form a Mini 4WD team between the business operator and the participants.

Step 2: Prepare for the hackathon

The team is preparing for machine design and parts production for the hackathon. Each team will proceed with development in cooperation with Suwa operators.

Step 3: Hackathon, Mini 4WD production & race entry!

On October 14th and 15th, teams gathered again at a hackathon in Tokyo. A mini 4WD will be assembled and raced.

As a result of the review, the winning team will exhibit a work (Mini 4WD) at the Suwa Area Industrial Messe ( ) to be held in October. Award.

Recommended for such people!

・ Designers and engineers who want to connect with manufacturing companies with the highest precision processing technology in Japan

・ Creators and designers who want to make things using design and modeling technology

・ Engineers and designers from different industries who want to interact and connect with each other

Why Mini 4WD?

Mini 4WD is a small car. At first glance, this toy that looks like a child's play is currently evolving as creators and engineers from various industries compete for technology and pack various technologies into its small body.

SUWACKATHON is a collaborative project with Fab Racers , a global mini 4WD x manufacturing community where many engineers and industrial designers participate. Fab Racers has a Fab Mini 4WD Cup and workshops to broaden the monozukuri culture and take root. We aim to create new value by combining creative creators and engineers with highly technical businesses in Suwa City.

About Suwa City

After the war, the Suwa area in Nagano Prefecture, developed mainly in the production of watches, cameras, and music boxes, was called “Oriental Switzerland”. In the 2000s, we changed the industrial structure and made use of the ultra-fine processing technology cultivated in the manufacture of precision equipment, and shifted to the manufacture of high-precision industrial machinery and automobile-related parts that meet the needs of companies.

In the city, where many companies with the world's top processing technologies are located, the skills and “manufacturing DNA” are still handed down.

About SUWA design project

Suwa City, Nagano Prefecture, is a project that conveys the potential and appeal of Suwa City's high precision processing technology through matching and co-creation with manufacturing companies and creators in urban areas. This year, we will conduct a factory tour with engineers and creators from the Tokyo metropolitan area and human resources related to new business development under the theme of “Mini 4WD”. After that, mini 4WD utilizing precision technology will be produced at Hackathon, and the high precision processing technology of Suwa City will be widely communicated.


“SUWACKATHON” consists of two parts : a factory tour in Suwa City , Nagano Prefecture , and a hackathon in Tokyo . Participants are required to participate in both factory tours and hackathons.

Under the theme of “Mini 4WD”, we will tour the factory together with engineers and creators in the Tokyo metropolitan area and human resources related to new business development. After that, mini 4WD utilizing precision technology will be produced at Hackathon, and the high precision processing technology of Suwa City will be widely communicated.
