Trivia:
- In the manga and the anime, Hikaru and Kaoru's relationship is represented by a single egg with two plant stalks coming out of it. Later, to represent their individuality, two huge flowers bloom from the same egg. The flowers are exactly identical, save for their colouring, which makes them easy to distinguish.
- His voice is slightly lower than Kaoru's.
- Another way to tell them apart is whenever they were seen together, Hikaru is mostly on the right side and Kaoru's on the left (in the audience's view).
- Ironically, he is often less mature than Kaoru, but shows that he is capable of being a mature older brother after the two make up their fight over Haruhi.
- He has a character song along with Kaoru named "Bokura No Love Style".
- Opposite of his twin, Hikaru is the seme or pitcher twin.
- Honey calls him "Hika-chan".
- When upset with Kaoru, Hikaru turns to Mori-sempai for advice and companionship, whereas Kaoru is often seen turning to Honey-sempai.
- He tosses and turns a lot when he sleeps, and for example, in episode 15, "The Battle in Karuizawa!", Kaoru wakes up on the floor and later complains to Hikaru because he pushed him out of bed.
- In the manga, Hikaru dyes his hair an ash color in order for others to tell the twins apart.
- In episode 20, when Hikaru and Kaoru were children, they wore dresses. This scene also takes place in the manga, the explanation being that their mother started to design child's clothing for girls and boys and used her children as models.
- When the twins were younger, their mother used to dye their hair. Hikaru's hair was dyed with pink and Kaoru's was blue. Coincidentally, during their false fight, they dyed their hair of the same color as the ones when they were children.
- His ringtone is the closing theme to the Ouran High School Host Club episodes.
- Hikaru and Kaoru are 178cm tall (5'10").
- The Hitachiin Twins have the same birthday as the Kurusu Twins from Uta no Prince-Sama.
- In episode 22, he, along with the others (excluding Tamaki), wore a forehead protector, just like the ninjas in the popular anime Naruto and Naruto Shippuden do.
- Hikaru's phone like some of the other hosts is blue to match his rose colour.
- He has been compared by many to Fred Weasly from the Harry Potter series
- Hikaru's seiyuu in the anime originally voiced Kaoru in the Drama CDs
- The person who does the voice for Hikaru is married to the person who does the voice for Haruhi Fujioka.
