Wa-Suta

 (わーすた; The World Standard) is the fourth iDOL Street group formed in 2015.

The group has a cat theme to them, and their songs have a variety of genres that take place all over the world. The group's image is described as a digital age idol generation that works towards the world to spread "kawaii japan idol" culture using social media and "real idol" activities, such as allowing video recording and photo taking at their lives.

Each of the members is learning a different language, and their official music videos have English subtitles.

In Summer 2018, they collaborated with Adexe & Nau on a Japanese/Spanish remix of the single "Yo Quiero Vivir"

The group has performed several times outside of Japan, including Japan Expo Paris 2017, Japan Weekend Madrid 2018, Japan Expo Thailand 2017, 2018, 2019, Kizuna 2018 in Vietnam, Anime North 2019 in Canada, and Japan Festival in Mongolia 2019.

Wa-suta released their first photobook “Wasuta – Wonderful Collection” in 2019.
