Morning Musume is a famous Japanese girl group. 
Becoming a member involves a special way of joining called an audition. A producer named Tsunku started the group in 1997. He held an audition on a TV show called Asayan. He wanted to find a rock singer for his band. Instead, he decided to form a girl group with five runners-up. These first five girls were Natsumi Abe, Yuko Nakazawa, Kaori Iida, Asuka Fukuda, and Aya Ishiguro. They had a hard job to sell 50,000 copies of their first song. They finished this task in just four days of promotion.
The group has changed many times since those early days. Members join through new auditions, and others leave to do other things. This is why the group stays fresh for many years. Sometimes, members form smaller groups called sub-units. One group was called Tanpopo, which sang slower and more mature songs. Another was Petit Moni, which featured Maki Goto. There was also Mini Moni, which was made for younger fans. These smaller groups allowed the singers to try different kinds of music.
Morning Musume has many amazing records in the music world. Their song "Love Machine" was a huge hit in 1999. It was their first song to reach number one on the Oricon charts. That single sold over 1 million copies right away. Another song, "Koi no Dance Site," also sold over a million copies. In 2012, they held a record for having 64 top-ten singles. This showed how much people in Japan loved their music. They have stayed important in the music industry for a very long time.
You might recognize their influence in modern pop music today. They helped make the "idol" way of performing very popular. They even started a tradition of performing in musicals. One of their shows was called "Love Century: Yume wa Minakerya Hajimanai." This showed that idols could do more than just sing songs. They could act and dance on a big stage too. 
Morning Musume is a highly influential Japanese girl group. 
The group's formation began with a specific goal. In 1997, Tsunku held auditions on the Japanese TV show Asayan. He originally sought a female rock vocalist for his band, Sharam Q. Instead, he decided to form a girl group using five runners-up. These original members were Natsumi Abe, Yuko Nakazawa, Kaori Iida, Asuka Fukuda, and Aya Ishiguro. To prove their potential, they faced a difficult challenge. They had to sell 50,000 copies of their demo single, "Ai no Tane." They achieved this goal in just four days of grassroots promotion in November 1997.
As the group grew, they developed a system of generations and sub-units. When a single became successful, new members were often added to the lineup. For example, the success of "Morning Coffee" in 1998 brought three second-generation members. The third generation arrived in 1999 with the addition of Maki Goto. These new members changed the group's energy and sound. Additionally, the group created sub-units, which are smaller groups made from the main members. Tanpopo focused on slower, mature songs. Petit Moni featured different members, while Mini Moni was designed for younger audiences. Some sub-units, like Mini Moni, included members under 150 centimeters tall.
The history of Morning Musume is marked by massive commercial milestones. Their 1999 single, "Love Machine," was a turning point for the group. It was their first single to reach number one on the Oricon Weekly Singles Chart. Upon its release, it sold over 1 million copies. Another major hit, "Koi no Dance Site," released in 2000, sold over a million copies as well. This single achieved the highest first-week sales in the group's history with 600,860 copies. Even when they did not hit number one, their sales remained enormous. Their third studio album, "3rd: Love Paradise," sold more than 800,000 copies.
The group's impact is visible in their impressive statistics and records. By 2012, Morning Musume held the record for the most top-ten singles on the Oricon chart. They achieved this with a total of 64 top-ten hits. They also held the second-highest overall single sales for a female group on that same chart. Their best-selling album, "Best! Morning Musume 1," sold 2,259,510 copies. These numbers demonstrate the massive scale of their popularity in Japan. Such success helped establish the foundation for many other groups under the Hello! Project collective.
Morning Musume also expanded the definition of what an idol could do. They began a tradition of performing in annual musicals. One such production was titled "Love Century: Yume wa Minakerya Hajimanai." This moved the group beyond just singing and dancing to pop songs. It allowed them to explore theatrical acting on a large stage. This helped break new ground for the entire idol industry. They showed that musical performers could be versatile artists across different media.
The group's structure has influenced the broader Japanese music system. Morning Musume served as the basis for several other groups. These include Country Musume, Coconuts Musume, and Ice Creamusume. The concept of "shuffle units" was also introduced to the industry. In 2000, all 16 members of the Hello! Project family were shuffled into three one-time groups. These groups were Akagumi 4, Kiiro 5, and Aoiro 7. They competed against each other to see which group could achieve the highest single sales. This created a sense of excitement and competition within the musical collective.
