Has your outlook as a photographer changed over time? 

Photography has always been a product of its time, and has always changed with the times. My photographs may change in superficial terms, but what I am basically expressing and my mentality remain unchanged.

You mention that it was photographing your mother’s lipstick that led you to take colour photography. What difference is there between shooting in B&W and colour, and what impact does this have on the final image? 

I can do every step by myself when I’m working in black and white. My ideal here has been to take full responsibility for every stage: shooting, developing, printing. When I’m working in colour, I just take the photographs and have the rest of the work done at a lab. When I started doing this, it was very refreshing to have the works be out of my hands and be able to look at them more objectively.

With black and white, I felt like I was clinging to the photographs throughout the entire process. When I started working in colour, I felt in a way as if I had been liberated from photography. Black and white is a world of artistic creation, while colour is the world of everyday life. At the same time, both black and white and colour are just approaches, and it doesn’t matter which you use.

The photographs of Yokosuka are commended for their grainy texture. What are the attributes that make a powerful image? 

The Yokosuka photographs are not intended to have a powerful impact. When I printed my first photograph, I realized that a photograph is a collection of ink grains on paper. I wanted to print those particles properly, so I developed the film at a high temperature. Grains are like units of time, and I tried to make prints as if I were counting them one by one.

I like the analogy between your background in weaving and the process of photographic development.

Do you think there’s something similar with the photographs themselves; weaving moments of time into history? 

Photography and textiles are very similar – they are both water works. It was a revelation to me that the colour-fixing liquid used for dyeing yarn and the stopping liquid used for photography are the same thing. Making textiles is very labour-intensive work. Photography is the work of evoking time using light. Both of them are jobs done by hand.

A lot of your work involves photographs of objects and possessions. Do you see photographs as being objects and possessions too? 

Photographed subjects are given new value and meaning, and by becoming part of a photograph they become almost eternal.

Did you take a different approach photographing the possessions of your mother and Frida Kahlo, compared with the clothing of Hiroshima victims (whose identity we might not know)? 

/hiroshima, Mother’s, and Frida all share the same intent in that they focus on what has been left behind. I took the same approach to photographing these three subjects, but Mother’s began as my own personal project, then after being shown at the Venice Biennale it became a photographic work that transcends my own personal concerns, expanding from the private to the public. This later shaped the specific development of /hiroshima and Frida.

I find it interesting that you don’t attach messages or captions to your photographs. How does that relate to the objects (clothing/possessions) that you photograph? Do you try to interpret the meaning that their original owner gave them? 

I consider my photographs to be creative rather than documentary, and I take them from my own point of view and with my own values. I believe that adding a message or caption to my photos would take away the viewer’s freedom of thought. I want people to be free to see my photos from their own perspectives, and to attach their own words to them. 

I cannot photograph the past. My work is based on encounters with things left over from the past, but which are in front of me, in the same space and time, in the reality through which I am living in now. In particular, the bombed artefacts of Hiroshima cannot become part of the past.

/hiroshima is very different to Yokosuka Story – how do they capture the aftermath of the war in Japan and the country’s relationship with America? 

I made my debut with Yokosuka Story, a series that is kind of a personal sentimental journey.

There is a connection between Yokosuka and the history of the atomic bomb dropped on Hiroshima, which played a huge role in ending the war, and which I documented about 30 years later. Yokosuka still serves as the home port for Asia’s largest nuclear-powered aircraft carrier. The post-war period is not yet over, and the reality is that Japan is still under US control. My photographic work, which started in Yokosuka, inevitably turned toward Hiroshima, and /hiroshima is still an ongoing project.
