Dwango has announced that support for the Nico Nico Douga app on Nintendo Switch will end on March 31, 2027. There are currently no plans for a Nintendo Switch 2 version.

As thanks for ten years of support, eligible users will receive a special profile flair and the ability to look back at their activities on the site. Provided that you have used your account to view a video on Nico Nico Douga through both the Nintendo Switch and the website or smartphone app by February 28 next year, you'll be able to see:
