What is Gojo Satoru’s type of girl?
In Jujutsu Kaisen volume 0, there’s a scene that he changed his mobile phone wallpaper to the Japanese female celebrity, Inoue Waka.

Waka? What kind of girl is she?

Here’s the video of Inoue Waka! Gojo Satoru in his high school days made her picture his mobile wallpaper.
Japanese binkini model, Inoe Waka
As you can see, she’s a sexy girl. She got popular as a bikini model with her excellent bust and thick lip. Some guys called her “Japanese Monroe”.
Gojo Satoru was a 2nd-year at Tokyo Jujutsu high school in the volume 0 episode. I think it’s very natural to like sexy girls like Inoue Waka as a teenager. At least, Gojo Satoru has a very normal sense of the type of woman.
Who’s Gojo Satoru’s girlfriend?
He doesn’t have a steady girlfriend for now.
Here’s a resource!

What does the tweet say?

The image in the tweet is from an official fan book of Jujutsu Kaisen. The reader asks the question to the author Akutami Gege.
The question asks “It seems Gojo knows he’s a cool guy. Doesn’t he want a lover?”
The answer is…
“I can’t imagine Gojo is being sincere against a particular woman.”
Mr. Akutami is always harsh against Gojo and treats him as a bastard. I think he doesn’t have any intention to describe Gojo Satoru’s love affair!
Does Gojo like Miwa Kasumi?
When it comes to Gojo’s type, you’ll remember the Juju Sanpo of the anime chapter 15.
The topic is everyone’s type and Gojo talked about the girl who seemed to be Miwa Kasumi. But it’s not unclear that he replied to the question of his type or not. It can be interpreted that they’re just chatting about their students.
Many Japanese fans of Gojo got despaired and confused with this Juju Sanpo episode 😅
At last, his ideal type is not officially announced. What I can say for sure is that his love interest is in women and his type is not eccentric!

Your comment encourages me!
I think, Gojo Satoru will make a great couple with Mei Mei. They always seems close together in JJK. If not with Mei Mei, Utahime is another best girls for Gojo Satoru despite she sometimes too harsh on him.
Teacher Gojo and Meimei! Wow, they’ll make the strongest couple and I bet they’ll rake in much money.
I agree that Utahime is harsh on Gojo. The official profile introduced in the Jujutsu Kaisen fan book says her stressor is Gojo Satoru🤣
