## Early life and child actor career
According to a Prime Video biography, Kamiki was born in Fujimi and was diagnosed with a rare disease soon after birth, surviving an illness from which only about 1 percent survived; his mother registered him with an agency to record his growth in celebration.[9](https://www.primevideo.com/person/Ry%C3%BBnosuke-Kamiki/amzn1.dv.gti.dc85d704-aedc-4534-9ea3-855f41aa66ec/ref%3Datv_pp_co_4) He appeared in his first television commercial at age two and quickly became one of the prominent child actors of his generation.[9](https://www.primevideo.com/person/Ry%C3%BBnosuke-Kamiki/amzn1.dv.gti.dc85d704-aedc-4534-9ea3-855f41aa66ec/ref%3Datv_pp_co_4)
His television drama debut came in 1999, when he was six, playing the stepson of Masahiro Nakai's character in the TBS drama *Good News*.[9](https://www.primevideo.com/person/Ry%C3%BBnosuke-Kamiki/amzn1.dv.gti.dc85d704-aedc-4534-9ea3-855f41aa66ec/ref%3Datv_pp_co_4) Through the early 2000s he appeared in a series of dramas, including *Quiz* (2000), *Namida o Fuite* (2000), *Mukodono!* (2001), *Wedding Planner* (2001), and *Tantei Kazoku* (2002).[9](https://www.primevideo.com/person/Ry%C3%BBnosuke-Kamiki/amzn1.dv.gti.dc85d704-aedc-4534-9ea3-855f41aa66ec/ref%3Datv_pp_co_4)
