Kazuhiko Yakushiji was born in Osaka, Japan in 1968.
In 1996, Yakushiji began to create transparent sculptures of marine mammals using materials like glass and acrylic.

He studied the ecology and behavioral characteristics of marine mammals at the Dolphin Research Center in Florida, USA. He also learned and obtained the basic glass engraving skills in Germany; however, most of the advanced techniques for the glass work are self taught. As for the acrylic work, he developed his original mist technique, in order to show a theme marine mammal light as mist inside the acrylic material.

In 2002, together with Bridgestone, one of the most well-know rubber makers in the world, Yakushiji started to take part in the artificial caudal finﾓ project formed by Churaumi aquarium in Okinawa for Fuji, a female dolphin which lost most of her caudal fin by the rare disease. This on-going project is the world very first experiment; therefore, there were a lot of challenges for creating the artificial fin using hi-tech materials from the beginning. In 2004, despite of　hardship and many trials and errors, the artificial caudal fin was completed and Fuji is now healthier than ever and able to jump as high as before she lost her own fin.

Yakushiji is always given inspiration for his art work by swimming with dolphins and whales. In addition, he sees marine mammals as his friends and/or family, so he dedicates his deep appreciation and his sense of intimacy for them in order to name his art studio HARAKARA which is an ancient Japanese word means friends and/or brothers.

Yakushiji love for marine mammals is truly genuine.
His art work is very original and one of a kind.
He is currently based and doing annual private exhibitions in Japan.
