It doesn’t end with just a kiss + kissdenpagumi.inc

This is Dempagumi.inc’s major-label debut song.

Thinking about the success story that began here fills me with emotion.

It’s a shame that Mogami Moga left, but with the new members joining, I’m excited for Dempagumi.inc’s future.

Let It Go!!PASSPO☆

This is the indie debut single by the idol group now known as PASSPO☆.

The music video, featuring members in flight-attendant-style blue outfits singing and dancing, is absolutely adorable.

It’s a powerful, upbeat, and encouraging song.

SoftlyRia Dizon

Leah Dizon, who was active as a talent, actually appeared on the NHK New Year’s Eve program (Kōhaku) back then in the “Akihabara-kei idol” category alongside people like Shoko Nakagawa—even though that’s not widely known.

It’s a mellow song that also served as the ending theme for TV Tokyo’s “Webtama.”

PurenessUeto Aya

This is Aya Ueto’s solo debut single; she was a member of the four-person idol group Z-1.

She’s an incredibly good singer.

Despite having no tie-in, it was a remarkable achievement for a debut song by a new female artist to reach the top five—the first since Kyoko Fukada.

Although she’s now active as an actress, she actually started out as an idol.

Believer – Song of Departure (Debut single released on April 21, 1999), U○ban edition

This is the solo debut single by Mikuni Shimokawa, who had just graduated from the idol group Cheki-kkko, produced by Kohmi Hirose.

It was used as the TV commercial song for KDDI Pocket.

Her vocal ability is a bit lacking, but that very unpolished quality adds to her charm.

Shokotan, who is now thriving as a variety TV personality, made her debut with this song back in her idol days.

She’s just as beautiful then as she is now.

Her voice is clear and expansive, and it’s truly captivating.

For the music video, in addition to the concept outfit, they reportedly prepared a total of 12 different costumes, including cosplay.

reasonAbe Asami

The debut song of Asami Abe, who drew attention as the younger sister of Morning Musume’s Natsumi Abe.

Her slightly nasal tone sounds youthful and cute.

The debut track was chosen from numerous candidates through a vote by 150,000 fans nationwide.
