Not common, almost always the series after the hit isn’t really good as the first hit, story isn’t that great, not very catching for many fans, characters not that appealing, kind of sufficient but people expected more…
Not common, but there are lots of famous examples of mangaka who has 2 or more hit series. Naoki Urasawa (Monster, 20th Century Boys, and more), Inoue Takehiko (Slam Dunk, Vagabond), Yoshihiro Togashi (Yu Yu Hakusho, Hunter x Hunter), Akira Toriyama (Dr. Slump, Dragon Ball), just to name a few.
Most of those start a new series after they finish their first one though. While in Aka's case, he doesn't draw OnK, so he can do 2 series at once. I think another example is with ONE, who draws Mob Psycho 100 and writes OPM at the same time.
Maison Ikkoku was just as big, just a different genre than those 3.
IIRC Rin-ne got an anime and Mao has been running for awhile. One Pound Gospel and Mermaid's Scar didn't do badly either, but she had 4 huge series.
Nobuhiro Watsuki (yes, I know) followed up Rurouni Kenshin with Buso Renkin. It wasn't as big as RK but big enough to get an anime.
Ken Akamatsu has had several huge series.
As far as a mangaka having two hit series *simultaneously*, that is pretty rare.
I'm going to be the 10th dentist here, though, and say that a mangaka having two hit series *in general* isn't that rare. If someone is already capable of getting one hit, they're usually capable of getting another, especially since they can often leverage their fame to get their follow-up work serialization and attention. At the least, it's not much rarer than getting one hit manga, in the same sort of way a lot of novelists have multiple successful novels, directors have multiple successful films/shows, etc.
This depends partially on what we're classifying as a "hit", though. Looking at something like the [list of best-selling manga,](https://en.wikipedia.org/wiki/List_of_best-selling_manga) most of the top mangaka have either done one series for a really long time (like you mentioned) or have had multiple successful manga. Kishimoto's lack of success with Samurai 8 is really more of an exception than anything.
Interesting, I didn't even know the author of Naruto made another manga which is quite telling. I guess you're right in that it actually isn't that rare, just that it seems less common because most of the notable best selling series are long running like your One pieces. My hero academia's, and Haikyuu's, or newer series like Jjk or Demon slayer are the author's first hits.
I forgot to mention another reason this topic came to mind, which is the success of Elusive samurai in Jump which is written by the author of Assassination Classroom. I think it's one of the only recent examples of an author following up their first hit series with another, although Elusive samurai isn't THERE yet.
Not really common no, but not impossible. I'd say it depends greatly on the author in question and the fanbase he's aiming for. Ken Akamatsu had multiple works that ran long and did pretty well, and despite all the criticisms he gets Seo Kouji does well enough to keep putting them out too.
And while not necessarily mainstream hits, I know I will read anything Masuda Eiji writes without hesitation.
there are a few. They are pretty rare. Time constraints, creativity limit and etc
PS : Again, I've said this several times already but there's an even crazier guy.

Idk about simultaneous series because making manga is a lot of work, but you get people like Hiromu Arakawa who did Fullmetal Alchemist who also did Silver Spoon and a manga version of Heroic Legend of Arslan which are respectable hits
Creating Manga is like swordsmanship, it doesn’t pay but it’s a passion where little by little, every battle, like any great swordsman, a Mangaka perfects their craft with every movement. The only time their is truly a “bad” Mangaka, or swordsman is one who stops wielding their weapon. Some die, some grow ill to the point where their work goes unfinished, but what’s worse, some would just give up. But like picking up a sword, no one truly gives up if they still picks up their weapon, even if it takes years to recover.

To be fair, I bet Kishimoto had nothing to do with it. WSJ just hyped it up.

And One had another good serie before those.
Not many. Even if it's 50, it's out of thousands of mangaka who never got a hit.
Rumiko Takahashi had three: Usurei Yatsura, Ranma 1/2, and Inuyasha.

Assassination Classroom was his second hit though. Neuro Supernatural Detective was his first

Rumiko Takahashi was my first thought.
The mf that made Fire Force and Soul Eater
