+ He enjoys playing the saxophone, but stopped due to health reasons.
+ He has once suffered from pneumothorax, the collapse of one lung due to immense pressure change in the chest cavity caused by trauma or a spontaneous rupture in the lung. Symptoms include shortness of breath and severe chest pain when breathing. He collapsed during a rehearsal of a performance for their single "Naisu na Kokoroiki".
+ He sleeps with a stuffed animal dog.
+ His least favorite season of the year is spring because he suffers from hayfever.
+ His family owns a Chinese restaurant named "Keikarou" in his hometown. His father is the chef.
+ He has a very noticeable birthmark on his left shoulder.
+ He joined Johnny's Jimusho for two reasons:
1. He is a huge Ken Miyake fan
2. He has a huge obsession with basketball. He saw Johnny's idols (SMAP) playing basketball on the TV. He said, "I Love SMAP", and thought that he'd get to play basketball with them if he joined. It was not until he was asked to audition did he realize Johnny's Jimusho trained young boys to dance and sing.
+The U.S. movie "Untamed Heart" (which starred Christian Slater and Marisa Tomei) was dramatized and Aiba played the lead role Adam! The play was staged last 22 October to 11 November at The Globe Tokyo in Tokyo, and November 16-18 in Theater BRAVA! Osaka. The work is being directed by Keiko Miyata. In 2005, Miyata also directed "Tsubame no Iru Eki," the last play that Aiba starred in.
+He was the host of Arashi's program Golden Rush Arashi which is now replaced by VS arashi.

We have already debuted for 5 years and a lot of things had happened . No matter how hard, painful or happy moment it was, we are always together.
Recently we are working on different things. I am very happy to see that we all are doing our job conscientiously.
To me, ARASHI is a good friend, but is also a good competitor. When i look back, i notice that i have brought troubles to the other members and i feel sorry for that. When i was sick & had to be hospitalized (due to pneumothorax), i could not help but think about all the members. They had to cover for me for the works that are supposedly mine.
Now when i look at the scar that was left on my right chest, it encourages me to keep working harder. Taking this opportunity, I would like to say things that I am awkward to express.
Matsujun, Thank you for always thinking of ARASHI more than anybody else.
Nino, thank you for clearing the atmosphere and encouraging ARASHI.
Sho-kun; Thank you because we are five different characters and it is you that's keeping us together.
Finally, Leader; Ohno-kun, I'm afraid that you have not demonstrated your leadership, but we are always relieved by your existence and personality. Thank you, I am going to rely on you Leader.
Let's work together toward our success. Finally, we are definitely going to make our dream "Get to the top" come true.
I am so glad that I am a member of ARASHI. 
ahaha i lahv him~!
