See the original story in Japanese.

Tokyo-based KDDI Mugen Labo, the tech incubator of Japan’s second largest telco, hosted a demo day event today. Five startups that graduated from the seventh batch of the incubator’s program showcased their achievements over the last several months, upon receiving assistance from 13 big companies supporting the initiative.

Dr. Joy, the service improvement platform for hospitals and other healthcare organizations, won the top award and the audience vote award.

Dr. Joy

Dr. Joy CEO Hiroaki Ishimatsu

Dr. Joy is a social platform aiming to eliminate waste in medical services. Dr. Joy CEO Hiroaki Ishimatsu is a practicing medical doctor who settled in a hospital for an year to find out what the platform requires.

Ishimatsu explained:

At hospital, we usually have to wait so long but a doctor’s consultation will finish in a minute. Medical offices are busily occupied with document processing. As soon as your doctor starts your consultation, his phone will ring and he has to care about another patient.

Dr. Joy aims to streamline this work flow, by helping doctors and other employees in a hospital share information resources while improving  their daily operations. The team is testing the product at several medical institutions, preparing to deploy the platform at four university hospitals.


Goal CEO Yusuke Nishiyama

Sakaseru enables a flower gift to be delivered using smartphones while consulting with advisors. Goal, the company behind Sakaseru, was founded by Yusuke Nishiyama, who owns a flower shop in Tokyo’s fashionable Roppongi district, and award-winning florist Akihiro Nozaki.

Via the Sakaseru platform, users can ask for one’s favorite flower designer by filling an online questionnaire form to create and order a bouquet for someone, regardless of one’s knowledge of flowers. The bouquet can be delivered to a designated location at a designated time.



Ingram allowa one to locate a product of choice for purchase, by taking a picture of it on TV shows or magazines with a smartphone camera. The app was developed by Tokyo-based Add Quality.

Add Quality CEO Soichi Matsuda explained:

Add Quality CEO Soichi Matsuda

The accuracy of our app in finding relevant results depends on how much its artificial intelligence has learned user cases. We would need to ask someone for additional data if we wanted to increase user cases, obviously a time-consuming task. That’s why we developed an independently-learning system that collects data from users.

While the app is still not good at qualitative search, it allows you to find relevant data without meta information utilizing a statistical observation method. The clipping feature in the app will provide  notification upon spotting a price decrease associated with a product of choice.


Meleap CEO Hiroshi Fukuda

Meleap has developed a sports game environment called Hado, leveraging a combination of several technologies such as spatial perception, head-mounted display (HMD) and motion sensors. It virtually reproduces decorated rooms and townscapes for users upon enjoying games or exercises.

The platform consists of a smart watch and a smartphone-connected HMD, aiming to serve users for affordable prices. Yuki Mori of Tokyo-based private broadcaster TV Asahi supporting this startup commented on their mentoring result.

We gave the Meleap team our expertise of engineering and video production as well as event opportunities. We henceforth plan to collaborate with the team for developing content and producing TV programs.

∞books (Mugen Books)

Mugen Books CEO Yukihiro Sada

Mugen Books is a non-inventory book publishing platform leveraging on-demand printing services. Users can create an article using a web app and order its publication just by pressing a button on the web.

Mugen Books CEO Yukihiro Sada has developed a service that allows authors to publish a book starting with a single copy, having brought 250 book titles. He found that many people are interested in creating their books but are unlikely to do so because of the possible expensive  and obstacles.

Published titles can be distributed digitally as well as in print, which can be put on sale at online bookstores like Amazon.

KDDI SVP Makoto Takahashi

In the final part of the Demo Day event, KDDI’s SVP Makoto Takahashi unveiled their strategy about how they will conduct the next batch:

I believe that the three-month batch was a memorable experience for participating startups. During the batch, we have given eight business-matching opportunities with our supporting companies to each of these startups. We have also worked on helping companies and startups co-create new ideas together, resulting in bringing out four actual cases.

KDDI will enhance the alliance program for startups in the next batch, adding Credit Saison and Hitachi to a group of the program’s supporting companies. In addition, they will strengthen regional expansion, starting with partnering with Osaka Innovation Hubto better nourish startup communities outside the Tokyo Metropolitan Area.
