AniTamaSai Saitama’s Largest Anime / Manga Event | OMIYA

October 18 @ 10:00 17:00

Anitamasai 2020

Anitamasai – Saitama’s largest Anime / Manga festival normally takes place in October annually in Omiya. Entry to the grounds is free. However, in 2020 on account of the Coronavirus it will be an online event.

Normally, there is over 80 booths and a wide variety of events. Some of the events require pre-registration. The cosplay fashion show is a highlight for many.

When and where is Anitamasai in 2020?

Anitamasai, Saitama’s largest anime and manga event, is being held online in 2020 on Sunday October 18th.


They normally have events on the main stage as well as three other halls. The main stage events are mainly live performances including some music and dance. The opening is at 10 am and the last performance goes on stage at 4.50 pm. Outside they will have anime cars and paraphernalia.

The tentative information for 2020 is that you can participate in events online. Online viewing is free. Whether events cost money or not is not yet known. The official website only has a press release currently to say that the 2020 event is an online event.

The event used to have an english webpage, but they have removed it (August 2019) and replaced it with a one page (2 paragraph) summary of what Anitamasai is. On that page they divulge that the aim of the festival is to create an image of Saitama being an Anime hub.
