Natsu-oto (acoustic ver.)Yuuri

What kind of sound is the “sound of summer ending”? Listening to Yuuri’s “Natsune,” that question comes to mind, doesn’t it? The title is read “Natsune,” and its very ring is beautiful.

The flowing piano and the lyrics that depict fireworks and the end of summer stir a poignant feeling.

The sparkling days of summer and the fireworks that hint at their end feel fleeting, expressing a sense of loneliness.

Layered with Yuuri’s powerful, unmistakable vocals, it becomes a summer song that seems to nudge you forward into the next stage.

“September-san,” who heralds the end of summer and brings in September.

It’s a classic by RADWIMPS.

As we pivot from the height of summer to the melancholic air of early autumn—the beginning of September, when traces of summer still linger—this song feels like the perfect fit.

I bet some people instantly hear its intro the moment September arrives.

Autumn can feel a bit lonely, but “September-san” carries a warmth that makes you feel there’s someone who stays by your side even as the seasons change.
