Trivia:
- His birthday is June 9th, making him a Gemini (the sign of the twins).
- He is 5'10". Every school check-up, he and Hikaru have grown the exact same amount.
- He is Blood Type B.
- There are three ways to tell the twins apart. One way is the parting of their hair, in which Kaoru is at the left and Hikaru is at the right. Kaoru's voice is also ever so slightly higher and raspier, which can be heard when they speak separately. Another way is whenever they were seen together, Hikaru is mostly on the right side and Kaoru's on the left (in the audience's view).
- A running gag is that Kaoru is described as often having nightmares that cause him to practically leap out of bed.
- He is the uke, neko or catcher in the twins' relationship.
- He is the mature one of the two despite being the youngest.

- Honey calls him "Kao-chan".
- It is revealed in "This Is Our Ouran Fair" that Hikaru is a talented equestrian, having driven the whole host club through the school campus in a horse-drawn carrige.
- His cell phone's ringtone is the opening theme for Ouran high School host Club, versus Hikaru's, which is the closing theme.
- Both Kaoru and Hikaru have one maid each, it just so happens that their maids are twins that look exactly like eachother, too.
- The Hitachiin Twins have the same birthday as the Kurusu Twins from Uta no Prince-Sama.
- He wore in episode 22 along with the others, excludig Tamaki, a forehead protector. Just like the ninjas in the popular anime Naruto and Naruto Shippuden do. The Host Club were actually cosplaying as the Shinsengumi, a private police force of samurai serving under the Bakufu back in the Edo to Meiji Eras of Japan, the forehead protectors were protective headbands members wore during battle, along with a blue and white haori
