Ogasun, who is active as an artist focusing on various arts, has his roots in his student days. I used to play the guitar and sing during the folk boom, but I stopped playing when I entered the workforce. Other than that, I lived a long life that had little to do with art, other than going to museums once in a while.​ There came a turning point in my life. It was the 2010 Aichi Triennale. I bought a ticket and went to see it, feeling as if something terrible was about to happen, and I was very surprised! I felt it. Around that time, a certain artist was having a solo exhibition at a gallery in Nagoya, which was also his first time! I visited the gallery. I remember listening to the artist's story while watching the work... It was a very refreshing experience. From then on, I started going to galleries in Nagoya, nearby areas, and citizen galleries whenever I had free time.

While I was doing this, I wondered why? I want to live again! So I pulled out Matsuoka's acoustic guitar, which had been dormant for probably 30 years, changed the strings, and started practicing. I think I practiced for about a year and a half. When I asked a nearby live house, they said it was OK to perform, so I completed my entry. What is the entry name? When I was asked, I only intended to do it once, so without thinking too much, I decided that ``Ogasan'' would be fine. It was September 2012. However, live performances don't end once; they continue forever. For some reason, since I was about to start doing live shows like that, I suddenly wanted to draw, but at first I only drew flags. I drew many pictures using ballpoint pens, marker pens, colored pencils, and other art materials that were around me at the time.

In the meantime, the work had settled on a postcard size, and the style of drawing in pen drawings with his favorite words ``LOVE PEACE SMILE'' and foraging with colored pencils had solidified. Of course, I started going to galleries, listening to music at live music venues, and attending live shows here and there. (Now that I think about it, I feel like I often had that kind of time!) After that, I decided to participate in an exhibition at a certain gallery because they said, ``I'm painting!'' This is my exhibition debut. That was in 2015. At that time, I changed my artist name to ``ogasun'' and started participating in live shows under the name ``Ogasan.''

By 2023, we will have held over 100 live shows, 16 solo exhibitions, and over 60 group exhibitions, and will be active in various locations. The number of artworks will be over 4500. I have also held live shows at galleries and live events and exhibitions at live houses. i also planned and held an art and live event called space L.I also create healing music using a synthesizer for video works such as movies and slide shows.
