Found this (partial?) interview from 2017. Many have probably seen it before, and if you know of any missing bits, definitely feel free to post them.

The first thing he said after seeing the Shonen Jump with chapter one of "JoJo's Bizarre Adventure" was, "First of all, those two colors are good."
Those "two colors," which are now only seen on article pages, refer to the black and red printing. Solid black lines with red shading.
"It gives it force, and expands the world view. I liked both seeing those colors and drawing them. I was a bit sad when they stopped being used. There's sort of a romance in them, as far as manga is concerned."
Hirohiko Araki made his Shonen Jump debut in 1980. Araki, a long-time reader of Shonen Jump, has described Jump in the '80s as, "like a minimally abstract, strange expressive medium consisting mostly of manga."
"I especially felt that when I saw Yoichi Takahashi's 'Captain Tsubasa' and work by Masami Kurumada [best known for Saint Seiya]. It's like, they just made the characters and story extremely simple. I found that amazing. I don't dare to do detailed descriptions of drawings, or depict the inner workings of characters. Even in the world of painting, people like Mark Rothko came along and abstract paintings ultimately became simpler. It's similar to that. The world that made me think 'this may be all I need' was in the early 80's and 90's Shonen Jump."
Although seemingly vastly different, Araki's style was influenced by the work of Kurumada and Takahashi.
"There was a time when I made a note of how many panels there were per chapter (laughs). I studied the work of these two artists and learned character creation and storytelling. I think Akira Toriyama was also an influence. I researched it and I think that 'Dragon Ball' was the first to use the minimum necessary elements. I think Shonen Jump makes it possible for everyone to influence everyone else."
And then, he continued like this. "Shonen Jump is a living organism that consists of various manga artists."
"Including the editors, I think. Each individual is like a body part of Shonen Jump. Various individual personalities get together as one body to give life to it. For example, when I see 'One Piece' by Eiichiro Oda and 'Naruto' by Masashi Kishimoto together, I feel like it's like yin and yang, or left and right, traveling along the same road. If either one is missing it feels lacking. There's those two, and Akimoto [best known for Kochikame, which ran in Jump for 40 years]. And it makes this life form called Shonen Jump. It lives so it also moves, its cells change over time, and its appearance may even change. I think that's because no work has the same personality, and no one part has to be the same as another to fit the body. If one part is the same as another, readers will shun it.
I'm no genius. I create while following a procedure.
If something has the same personality as another, readers will shun it; it's this Shonen Jump in which "JoJo" unleashed a truly unique personality.
"In music, there are guitarists you can recognize right away just hearing a little of the music. I want to create manga that's recognizable as mine at a glance. I was told in the beginning, 'Don't create anything that's similar!' (laughs)."
While treating individuality as important, he's repeatedly said his work is "main street."
"I'm traveling down main street (laughs). Artists like Kurumada and Toriyama create manga that's special. I draw and shade and remain faithful to the art. But, everyone does planar drawings. It's incredible. When I talk to them about it, it seems that they do it unconsciously, so they're probably geniuses. There are geniuses in Shonen Jump now too. Some manga, when I first read them I can't follow. It's like they aren't normal and don't make sense, but as I read I start to get it. Shonen Jump's solid popularity is because of those kinds of manga."
It's interesting that Araki, who may be called a genius himself, thinks of other artists as geniuses.
"I'm no genius. I create while following a procedure."
It's true that when you read "Araki Hirohiko's Manga Technique" written by Araki three years ago, you can tell that he creates in a logical way.
"I think that about myself (laughs). I also read books by Hitchcock on making films, 'manga for beginners' type books, and I even learned things from my teachers in junior high and high school art classes. I just brought those theories I learned to manga. I analyzed manga with my friends since elementary school. My friends would say things like, 'Mizuki Shigeru's backgrounds are scary, and Kazuo Umezu's people are scary.' (laughs)"
I wanted to discuss manga with other Shonen Jump artists.
In the '90s, Araki was in the middle of the fourth part of "JoJo" when Shonen Jump hit its peak circulation.
"I was in my 30s, about 10 years after my debut. I was sort of in my prime. I wasn't a rookie, and I was starting to really understand how to create manga. When I think about it now, I was fortunate at that age to have been published in Shonen Jump when it was really jumping (laughs). When I say 'jumping' I don't mean only circulation numbers, but also the content."
He seems unaware that when Jump was "jumping," he was one of the catalysts.
"There's always something above you. There are always more popular creators. I never felt I was like that."
He never felt that any other creator was a rival.
"Maybe it's because I created this kind of manga, that I didn't feel that way. But at the same time, I didn't feel much camaraderie with the other artists either. I guess I never had much of a competitive spirit (laughs). But I do sometimes wish I had discussed manga more with other Jump artists, like I used to with my friends in elementary school. I had no experience as an assistant, and no friends who were assistants, so I had no chance to talk about manga. Even now, I'd like to talk to them."
The inexpensiveness of Shonen Jump as a printed publication adds to the romance of it.
When entering the 2000s, Araki came to feel that the 19 pages per chapter mandated by Jump was unsatisfactory, and he moved to Ultra Jump where he felt he could produce higher number of pages. There are things he felt for the first time after leaving Shonen Jump.
"About four years ago (in Weekly Shonen Jump) I did a series of Rohan Kishibe stories, which I hadn't done in a while, and when I saw them in print I thought, "Ah, this is Shonen Jump!' There's a certain scent to it. Like I said, there's a certain romance to the inexpensive printed magazine. I wonder if that same charm will continue on. As printing technology evolves, and paper becomes slicker or digital, I'm concerned that the romance will disappear as new things are built and the old are discarded. There is also romance in the thinly colored printing. If you ask manga artists, we have preferences as to the print colors. But I don't get to select them myself. I don't like the times when the ink is blue. I feel like, "This isn't my manga!' (laughs). It's like… there's just something about printed ink. For example, Go Nagai draws women's skin with a stroke of a G-nib pen, and it comes to life. A manga artist feels that 'something' when drawing, and wants the reader to feel it too."
Many people around the world have felt that "something" from Araki's work, and continue to be influenced by him. What does he think is appealing to people about his work?
"Well, it's really nice to hear that, but I don't have any idea myself. Maybe it's the way I draw people. I don't rely on robots or equipment. I decided in the beginning to create human will and physicality because that's all I think about. Oh, and also, I recently met with my first editor and he said, 'You've been watching horror movies all this time, haven't you? I think that's good.' When I thought about it, I had been. Even if there's only one really bad horror movie at a certain rental shop, I rent it anyway expecting it to have some redeeming quality. I've been watching them for decades, so maybe something from one of them showed up in my work (laughs)."
What is Weekly Shonen Jump to Hirohiko Araki?
It's like a nostalgic home town.
I've been with it longer than I lived in my family home,
and I was raised with it. It feels nostalgic when I go back to it.
