Misato Watanabe [MV] “Folding Umbrella”

This work was released in a milestone year marking the singer’s 40th anniversary since debut.

Performed by Misato Watanabe, it was released as a single in June 2025 and was also included on the commemorative best-of album “ULTRA POP.” As the first song provided by Noriyuki Makihara in roughly 20 years—who wrote both the lyrics and music—it has generated considerable buzz.

It’s a mature ballad that delicately portrays care for a loved one and the lingering afterglow of parting through small scenes from everyday life.

It’s recommended for the rainy tsuyu season, when you spend quiet time indoors and find yourself recalling kindness someone once showed you.

Its heartwarming melody and vocals gently complement the moist, tranquil air of the rainy season.

With breath-infused expression and ventures into higher registers, it draws you in with a new, humidity-laden vocal quality that differs from her previously powerful rock vocals.

The intricately crafted, Vocaloid-like melodic lines are also captivating, making it a song that gently stays by your heart when you want to quietly face your feelings alone on a rainy season night.

This is a single released in April 1997, a RAZZ MA TAZZ track chosen as the opening theme for TBS’s “COUNT DOWN TV.” The gentle tones of the acoustic guitar and the smooth, beautiful melody envelop the heart.

Using a hydrangea found at a flower shop as its motif, this love song portrays the gradual deepening of a couple’s relationship.

Sung gently yet poignantly from my perspective—as someone who notices the other person’s lies but still wants to cherish the relationship—this piece weaves a rain motif into a light pop sound, with stage-like scene descriptions that resonate deeply.

It’s a track you’ll want to savor slowly in your room on a softly rainy day.
