The city of Matsumoto is famous in Japan for its apple.

Apples from this area are sweet and slightly hard.

However, the sales of apples in the city have decreased 30% over the past 20 years.

The sales of their biggest industry has affected the city financially.

Our objective was to solve this downward trend in the hard apple sales.

The dental checkup using the Dentapple is very simple.

First, authorize the sticker on the apple through a smartphone app.

Bite into the apple by following the navigation.

Answer questions as to whether you felt the pain when biting the apple, and send the picture.

The information will be diagnosed by associated dentists, and you will receive a diagnosis within 24 hours.

If you feel unsure about the diagnose, you can always make a reservation to your nearest dentist through GPS.

This ‘dental diagnosis apple’ started to go on the market on November 8th, the day to commemorate “Good Teeth Day” in Japan.

It was shipped out to many stores, and instantly gathered people’s attention.
