I have been a fan of NiziU since their early days ... their early songs e.g. Make You Happy, Beyond The Rainbow, Take A Picture, Poppin Shakin, Super Summer and Clap Clap are amazing songs (and have amazing choreo)
They made their Korean debut in Oct 2023 with "Heartris", which is also an amazing song ... and seeing NiziU on Korean music shows felt amazing ... they even got their 1st Korean music show win on Show Champion!!!
In 2024, they focused exclusively on Japan (which is like 99.99% of their fanbase) .... they performed at festivals in Japan, both Japan-run ones and Korean-run ones e.g. KCON JAPAN ... and they have just finished their winter tour (in Japan, of course), and released their new album tied to the winter tour, called "Awake", with the title track "Yoake" ... (however, being exclusively in Japan since the start of 2024 has meant that NiziU has sadly lost a lot of non-Japanese fans...)
"Overseas Activities" are listed in their 2025 plans ... I'm really looking forward for their Korean comeback!
