According to Vulture, Yes.
Although this specific scene is not mentioned, Ran and other Kurosawa's works are and therefore it is likely the case.
Anderson remained mum back in Berlin when questioned as to how, exactly, Kurosawa’s work figures into Isle of Dogs. But even on the
first watch, a viewer is smacked right in the face with a panoramic
visual grandeur that could only belong to the painterly master of yore
— just rendered on an itsy-bitsy scale. Some of the references are
more Easter egg-ish and some have been integrated into the general
fabric of the film, but either way, Kurosawa’s all over the place.
For the benefit of the casual viewing public, Vulture has made five
selections from his extensive filmography that most closely inform
Isle of Dogs, as a pre- or post-viewing companion to this worthy
homage. Now strike up the taiko drums and read on...
And also stated here:
Isle of Dogs also pays a good deal of homage to Kurosawa’s period-set
films as well. The score for Seven Samurai is heard on the soundtrack
at one point (as is the score for Drunken Angel), and the same movie
gets some shot-for-shot reference too — for details on that and its
tributes to Throne of Blood, Ran, and more, Vulture has a great guide
to the Kurosawa Easter eggs. Stray Dog is also discussed there. But
some eggs are likely still hidden given what Anderson said during a
masterclass Q&A last year: “The reason to hide your [inspirations] is
because you’re trying to steal them, and if you can sneak them in then
you’ve gained something without having to lose something.”
And a bit more of a confirmation from Indiewire:
As for the second source of inspiration: It’s none other than Akira
Kurosawa. The director has never been one to shy away from his
admiration for Kurosawa, and he teased that “Isle Of Dogs” will be a
full blown homage to the Japanese icon. “The new film is less
influenced by stop-motion movies than it is by Akira Kurosawa,”
