Makoto Kikuchi (Hiromi Hirata) is a Japanese artist credited under a dual-name listing. The performer is also known as Hiromi Hirata (平田宏美), and the available biographical data places the person’s birth in Hiroshima, Japan, on February 19, 1978.
That combined credit is useful in Japanese music and related catalog listings because the same performer may appear under different names across releases and databases. Keeping both forms together makes the entry easier to identify and helps connect related credits without confusion.
