Grand Prix winning of NIKKEI National Geographic Photo Award 2016

I'm awarded Grand Prix of NIKKEI National Geographic Photo Award 2016. I'm very glad that I got the opportunity to look towards the world of small creatures like this in this way. Also, taking pictures at night in the ocean is impossible without the cooperation of the local people, so I would like to say thank you once again. In addition, I would like to thanks again for each of equipment manufacturers who support me from every day.
