What is your name?

Katsunori Aoki

Which country do you wish to represent?


What did you have in mind when creating your T-1 T-shirt design?

What initially came to my mind when I thought of "Japan" was Fujiyama Geisha.
I talked with Abe-san, who produced this design with me, and we wanted something that exists from long ago, and still exists now, from a “Fujiyama Geisha” point of view.
It was just before the Iris Festival of May, so I thought koinobori (carp streamers) may be nice.

What sort of places or situations will best fit your T-shirt design, do you think?

I don't have a specific place in mind, but I would like to think of a family wearing it.
Just like the koinobori song, the father, mother and children side by side.

Has your final T-shirt design turned out the same as you initially imagined it would?

I made detailed variations of the design, some having defined outlines, some not.
In the end, I decided to blend the outline into the t-shirt itself.

When you were designing your T-1 T-shirt, how did the process compare with your normal work?

I thought that the illustration itself already expresses Japan. When you think about being strong and cool, it might be better to design “Japan” in the back, but picturing people actually buying it, I put in the illustration fairly small around the chest. I thought that it would be easier for people to image themselves wearing a simple design like this. (I haven't made my final decision yet. I'm planning to decide when I check the proof.)
