Where can I watch One Day legally?
Right now, One Day is on Rakuten Viki. That said, anime licensing varies a lot by country — what's on Netflix in Japan might not be on Netflix in the US. If your go-to platform doesn't have it, try the other services listed above.
Is One Day on Netflix or Crunchyroll?
Can't confirm either right now. Both platforms rotate their catalogs pretty often, so it's worth searching directly on each one.
Is One Day available with an English dub?
Dub availability depends on the platform. Crunchyroll has been expanding their dubbed library a lot recently, and Funimation (now merged into Crunchyroll) historically had the biggest dub catalog. Check each platform's listing for One Day.
Can I watch One Day for free?
Crunchyroll offers a free ad-supported tier for some shows. Most other platforms require a subscription, but many offer free trials for new users. Tubi and Pluto TV occasionally have anime in their free rotation too.
