成宫宽贵是当前大受欢迎的个性派新秀，活跃于影视两个领域，在年轻女孩子中很有口碑。

成宫出生在东京，而双亲是冲绳人。他幼年坎坷，自小父母离异，初中时母亲又撒手人寰，此后和弟弟一起由外婆照顾。学生时代的成宫并不是一个爱念书的乖孩子，经常旷课逃学。

2000年，成宫走上了演艺之路。他过关斩将在试镜选拔中脱颖而出，成为话剧《残存人类、爱之本质》的主演之一。这出充满后现代味道的戏是著名剧作家Brad Fraser的作品，由日本著名舞台导演宫本亚门执导，在当时很受关注。

此前并无表演经验的成宫以其出色的表现获得了好评。此后，成宫的星路走得顺风顺水。次年，他出演《溺水的鱼》初登大银幕。02年，由于J-PHONE广告和《极道鲜师》里那个暗恋英语老师的男生，成宫的知名度迅速飙升。接着，03版《高校教师》里的邪恶牛郎、《少女杀手阿墨》里惊鸿一瞥的杀手令成宫的演技获得了进一步肯定，粉丝群的规模也逐日壮大。04年，他获得了主演电影的机会，在改编自同名漫画的奇幻《下弦之月》中和栗山千明演对手戏。

这些年来，成宫每年都有不少新作问世，他拥有独特的气质，戏路却不拘泥一格，《娜娜》系列中憨直的吉他手、电视剧版《蜂蜜与四叶草》中不羁的美大学生、《爱无罪》中心事重重的彷徨者、电视片《无法守护》中的变态狂人、《六宅一生》中的边缘青年……每一个角色都展现出保有本真但有所不同的成宫宽贵。值得一提的是，他还曾经为动画电影《翡翠森林-狼与羊》中那只胖乎乎的小羊咩咩配音，展现出难得的柔弱的一面。

Narimiya Hiroki, born Narimiya Hiroshige, is a Japanese actor and model. His parents divorced when he was young, and in his 3rd year of junior high school, his mother died, and he and his brother were raised by his grandmother. He had made a promise to his mother to become serious about acting and soon dropped out of school to pursue his career.

He soon debuted in 2000 in the play "Horobikaketa Jinrui, Sono Ai no Honshitsu to wa (Perishing Humankind, What is the Essence of Its Love?)". Hiroki was chosen for the part of Kane out of the 3000 actors who auditioned.

In February 2001, he made his movie debut in "Oboreru Sakana". In 2002, he appeared as Noda in the television drama, "Gokusen". With his life-sized performance in this role, Hiroki won both serious acclaim and popularity. In 2003, he performed in his first-period film, "Azumi", which became a box office hit and allowed Hiroki to display his swordplay skills from daily training.

On December 2, 2016, Narimiya announced retirement from the entertainment industry following allegations of illicit drug use. The drug allegations were never confirmed, but Hiroki insisted on retiring. He is currently devoting himself to other personal artistic projects, but not in the field of acting.
