In the time period of long-life, it's not unusual for people to live until 100 years old. Although not many people wish to live till 100.

On the other hand, Japan has a traditional culture of respecting elders. For instance, traditional performing artists work all the way through their lives.

It inspired us to create a documentary films focusing on people of 100 years or older, who's challenging to their risks and overcoming their difficulties.

The film is not only a fancy 'images' , but a 'truth' of life story that proves audience that life is enjoyable regardless your age.

We conducted research in major regions such as Europe, America and Africa, for musicians over the age of 100 who exemplify a “Happy at one hundred”.

In order to qualify, you must be aggressively enjoying your life, while also gathering empathy from others.

Of those that qualified, we elected Kyosen Kineya, who was 104 years old at the time, as the best person.

After we casted Kyosen Kineya, it took approximately 1 year to hold her performance, due to her physical condition and difficulties in negotiating with her family members.
