Seiko Omori – Goodbye @ Mori, Michi, Ichiba 2016

A song included on the first single of 2012, “PINK.” Her a cappella performances of this song, singing while looking at each audience member’s face, are particularly striking.

She mentioned that she loves seeing everyone’s faces from the stage during live shows.

It’s a captivating track that delivers a powerful message with her strong, resonant vocals.

The song, with its colorful, poppy, bubblegum-like base reminiscent of candy and chewing gum, is delightfully cute and striking.

Yet in stark contrast to its bright sound, the darkness lurking in the lyrics stands out.

It’s a track that makes you want to uncover the message hiding behind the brightness.

Wedding BellOmori Seiko31rank/position

Seiko Omori “Wedding Bell” Music Clip (short ver.)

Originally released in 1981 as a song by the three-woman group Sugar, this track was covered and released in 2016 by singer-songwriter Seiko Oomori, who enjoys strong support from younger generations.

The mismatch between the catchy, fairy-tale-like brightness of the music and the lyrics, which are imbued with a terrifying level of resentment, is striking.

Because of that contrast, you can feel the intensity of the emotions held by the female protagonist in the lyrics.

The music video, which shows her singing in a blood-soaked dress, is also a must-see.

When I first listened without looking at the title, I thought, “What a nostalgic melody…” and the moment I saw the title, I felt a pang of frustration (laughs).

That’s how perfectly the song—and the melody carried by the vocals—embodies a captivating sense of nostalgia.

The lyrics make you want to dig into their meaning, but setting that aside, this is a track you can dive into purely through its sound.

Seiko Omori “Party Dress”

This song is included on the 2012 debut single “PINK.” Its serene atmosphere and beautiful vocals evoke a traditional Japanese sensibility.

However, the lyrics depict painful yet real events, making it a striking and impactful track.

Fan letterOmori Seiko35rank/position

Seiko Oomori “Fan Letter”

It’s a gently soothing, ballad-style song, but the lyrics are about life and death.

Even so, it’s very much her style, with familiar TV programs appearing, like “Iitomo” lit up in a quiet room.

The final line of the song, “I want to live, I want to live, and I tremble,” is deeply moving.
