I'm not sure why this has come to mind, but was thinking earlier that in a lot of video games Oda Nobunaga is seen as a villain, usually in cohorts with a devilish creature or figure. I was just wondering if this is rooted in history at all?
A lot more can be said about this, but you may like u/ParallelPains clickbait style but very comprehensive take on Oda Nobunaga here.
Video games (of the hack and slash variety) often simplifies relationships and play up Nobunaga's brutal side, since he is often known for his brutality.
However, on the whole, I would say Japanese greatly respect, even admire Nobunaga. Pre-Meiji people saw him as a great lord and warrior. Though they criticized certain actions (and maybe unfairly blame him for some others), Hideyoshi and to a lesser extent Ieyasu derived some parts of their legitimacy as successors to his legacy, so they showed him great respect.
In the Imperial era, as briefly touched upon in the April Fools thread, Nobunaga was seen as a revolutionary modern Japan should imitate. This I would actually say continues to this day amongst some authors and essayists, justified or not.
More in depth depictions of Nobunaga in fiction (novels, manga, tv drama, movies), especially since the 90s, also tend to be more nuanced, depicting him as a revolutionary, a quiet idealist, an charismatic (if ruthless) boss, etc. For instance, NHK's Taiga drama for the last two years gave his brief, supporting role as the enemy a fairly nuanced depiction: quiet, strict, perhaps ruthless, but processes great insight and is frighteningly efficient.
He also regularly tops internet polls on popular and favourite Sengoku figures, and is apparently the most often searched one on Google by a large margin, so there's that.
