NiziU are on their Korea 1st Mini Album. The music video for 'Sour Grapes' went up on the official JYP Entertainment channel on September 28 at 6:00 PM KST, and it is a short vertical one at 42 seconds rather than a full-length video.

The description names 'Sour Grapes' as that Korea 1st Mini Album and gives the release as 2026.09.28 MON 6PM KST, with a listening link sitting alongside it. The video went up at that same hour, so the post and the release landed together.

At the time of writing the video carries 137,999 views, 6,977 likes and 91 comments. That is one reading from the official page rather than a running total, and the page itself keeps the live figures for anyone who wants to check them.

NiziU were formed through JYP Entertainment and have been based in Japan, releasing there. That is what makes the wording on this one worth a second look, because it is not the group's first mini album overall but the first in a separate Korean count.

Context for International Fans

Korean and Japanese release counts are kept apart from each other, so a group that has already put out records in Japan can still be on its first Korean mini album. The Korea 1st label in the official post is what marks the start of that separate count.

Why It Matters

For anyone tracking NiziU release by release, the official post settles which count this one belongs to, along with the title, the hour it landed and where to listen.

What to Watch Next

The release is already out according to the official post, dated 2026.09.28 at 6PM KST, and the listening link sits in the same description.
