前衛華道家。代表作の「花坊主」や、舞踏家大野一雄とのコラボレーション「天空散華」など、いけばなの既成概念を超えた表現で知られている。その創作活動は「いけばな」にとどまらず、書、ガラス、絵画など多岐に渡る。土門拳に師事し写真を学び、自らのいけばなを撮影することで刹那の美を写真に残した。
Nakagawa is one of the rarest artists in danger of extinction in the modern world. While being trained in flower-arrangement, Nakagawa was not limited to traditional flower arrangement arts but made his own unique installation works, using flowers, fruits, potteries, antiques, Japanese papers and natural stones. In addition to flower works, his works included glass objects, painting, calligraphy, and performance arts collaborating with contemporary dancer Kazuo ONO. He also learned photography from Ken DOMON and took photographs of his works by himself.
