While he's undeniably a famous historical figure in Japan, my impression is that the majority of Japanese people don't have any strong opinions about him. After all, how many people actually care so much about historical figures when they're busy watching cat videos on YouTube? But for the people who do have some interest, I assume many have mixed feelings on the matter, which is natural for citizens of a former military dictatorship turned democracy only because they lost the world war. The rest are far-right people who, as you can imagine, hate him with a passion, though I do hope they're only a minority of Japanese people whose voices are amplified by Twitter echo chambers.
I'll have to hunt down the article that talks about it, but McArthur was actually "Emperor of Japan" for a few years, in everything but title.
I had several people point out his office on the top floor of a building facing the Emperor's Palace (some of the priciest real estate on Earth), in hushed, reverential tones.
Yes, he did have a strong political influence during US occupation, and yes, there may be people who worship him, but I can guarantee that it's not the norm. I'm actually fluent enough in Japanese to know this.
Because the kinds of people who likes to pile on McArthur are mostly far-right people who are trying to discredit the positive things he did, especially his team's work on drafting the current Japanese constitution which established a democratic system with strong safeguards for human rights. It's not McArthur's own character that I'm taking issues with.
