Princess Princess (プリンセス・プリンセス, Purinsesu Purinsesu; commonly referred to as Puri-Puri) was a five-piece Japanese pop/rock girl band active from 1983 to 1996. They previously released music under the names "Julian Mama" (ジュリアン・ママ, Jurian Mama) and "Akasaka Komachi" (赤坂小町).

After being assembled via open audition of 1400 hopefuls as the female music group Akasaka Komachi by TDK Records in 1983, the band was housed with their manager in the Tokyo suburb of Nishi-Nippori for over two years to develop their musical skills and experience. In March 1984, the band made the first of several appearances on Japanese television. In 1985 the band transferred from TDK Records to another management company, changed their name to Julian Mama, but did not release any singles or albums.

In May 1986, the band made their recording debut with the EP Kiss de Crime, released by CBS Sony. In August 1986, the band transferred their management to Shinko Music Entertainment. In May of that year the CEO of Shinko had declined to represent the band, but the company employee Emiko Ichimura, who had seen the girls' live show and believed in their success, eventually persuaded the company to take them on. The band made seven concert appearances in 1986, playing in very small venues around Tokyo.

In 1987, the band released their first single as Princess Princess, "Koi wa Balance" ("Love Is Balance"). The single's lyrics were credited to the band's guitarist, Kanako Nakayama, but the music was credited to well-known music producer Saburo Suzuki. At this time the band decided that they would produce their own sound, so all new compositions from then on was credited to band members, with Nakayama and drummer Kyōko Tomita generally splitting the lyric duties while lead singer Kaori Okui took over two thirds of the music credits over the band's career. The band still struggled for fan notice, playing approximately 60 small venues, and releasing their second single, "Sekai de Ichiban Atsui Natsu" ("The Hottest Summer in the World") to little market response.

In 1988, the band made their major leap for recognition, releasing their second studio album Here We Are in February and touring during the summer in support of it. The album, which include the songs "19 Growing Up", "My Will", "Go Away Boy" and "Romancin' Blue", demonstrated significant artistic development and was met with increasing commercial success. The single "Go Away Boy" reached the Japanese Oricon Top 20 Singles Chart. In November, the band released their third album Let's Get Crazy which furthered their commercial momentum with another batch of rock anthems and popular concert standards. From November 1987 through February 1989, Princess Princess made 100 concert appearances, progressing from small clubs to regional public halls. In April 1988 the band accomplished the first goal they had as a group: playing the Shibuya Public Hall. Tickets sold out within two hours, causing their manager Ichimura to cry in her office; the band reportedly initially thought Ichimura was reacting to bad news until being informed of their sell-out. This period of increasing success culminated in their January 1989 shows at the Nippon Budokan, where Princess Princess became the first all-female group to play that important Tokyo venue.

1989 brought the band to the peak of their popular success. In April, their seventh single "Diamonds" was released, which reached No. 1 on the Oricon chart; the single also became the first CD single to become a "million seller" in Japan. In July, "Sekai de Ichiban Atsui Natsu" was re-released, and it also went to No. 1, earning Princess Princess the two top spots of the yearly sales rankings. The group made their first nationwide concert tour that summer, and finished out the year by releasing their fourth album, Lovers, which did not feature any single, but reached the No. 1 sales position in the albums chart.

In 1990, the band consolidated their media presence with another nationwide tour, playing 56 venues, including major sports arenas. Their ninth single "Oh Yeah!" was released exactly a year after "Diamonds" and also reached No. 1. The band again finished the year releasing another album, the self-titled Princess Princess, and the single "Julian", also a No. 1 single.

The following year saw Princess Princess continue their string of No. 1 singles with their 11th single, "Kiss", released in May, which would prove to be the band's last chart-topping song. Their next single "Seven Years After" peaked only at No. 3; the band's single sales into the 1990s never approached the heights of their 1989 period. In December 1991 the band released their 6th album, Dolls in Action.
