"Jiwaru Days" (ジワるDAYS) is the 55th single by Japanese idol group AKB48.

The single features departing member Rino Sashihara as the center performer.

This made the band second to only B'z in terms of overall best-selling artists in Japan.

[2] Despite this, this was considered average in terms of AKB48's past sales, which was attributed to the cancellation of the group's General Election for 2019, which gives fans the opportunity to vote for their favourite singer from the group to front upcoming projects.

It is their 1st special single for 1st generation members released on November 20, 2022.
