Aiba Masaki is the Arashi member I knew the least about. He was totally off my radar. I have seen his experiments in G no Arashi and few episodes of his pet shows. Nothing was extraordinary to me.  My rule for writing these guides is that I have to watch at least five shows or movies the actor has been in (Taemin's Stalker's Guide was an exception), so I queued up the five I was going to watch, without high hopes. I am so glad I was wrong. So for him, I am going to list EVERYTHING I have seen him in:

P.P.O.I. came out in 1999 and Masaki stars in this along with Yamashita Tomohisa, Nakamaru Yuichi, and Akanishi Jin. He is the suave ladies' man of this drama narrated by Takizawa Hideaki.

In Yoiko no Mikata, he starred as a guest (it was Sakurai Sho's drama) and he was also a guest in Ninomiya Kazunari's Freeter, Ie o Kau.

Engimono: Kuru ga Mama - I only found two episodes of this online, not subbed, and Masaki plays a poker player. His voice is TOTALLY different, but it is him.

My Girl - WHY in Kami-sama's name had I not been recommended this drama sooner? It is now in my top 10 favourites. Hands down, I love this drama.

Bartender - I liked it, it was a good, solid drama. Not bad but not AMAZING either.

Miracle: Devil Claus' Love and Magic did not impress me. Despite its great cast, it just did nothing for me.

Saigo no Yakusoku - All of Arashi are in this one, as well as in Pika*nchi Life Is Hard Dakedo Happy, Pika**nchi Life Is Hard Dakura Happy, Pika***nchi Life Is Hard Tabun Happy, and Yellow Tears. I have seen them all and I think I have written reviews for all of them.

And then there's Kizoku Tantei. I have a hate/hate relationship with this format of the show (just look at my Dropped and Not Interested lists).  His demeanour towards the leading actress did not help either. But it is winning awards so my opinion is in the minority.

I am getting ready to watch Yokoso Wagaya e now... if I can find English subs. So far, Japanese and Indonesian subs are all I have found.

Early Life

Masaki's family consists of his parents and a younger brother who is four years his junior. He was raised by his grandparents the first four years of his life as his parents had just started running a Chinese restaurant named Keikarou at that time.

- He is a huge fan of TOKIO.

- In Spring 2002, Aiba-chan decided to "buff" himself up after he had collapsed during one of Arashi's rehearsals due to the disease known as pneumothorax.

- He played baseball during elementary school and basketball during high school. He joined his high school basketball team because he got along “too well” with the people in his school’s baseball and soccer teams and felt scared/nervous.

- There is a large beauty mark on his shoulder that he refuses to let be photoshopped/edited out by magazines, saying that it's how his family can recognize him if he gets lost.

- He lived in Takizawa Hideaki's house for about a year before he debuted at the age of 16. He did all the cooking and laundry.

Entering Johnny's and Acting

Masaki has stated that he joined Johnny's Entertainment for two reasons: One is that he was a big fan of Miyake Ken, and the other is that he was watching an episode of Love Love SMAP, where they were playing Basketball. He thought if he sent an application to Johnny's Entertainment, he would be able to play basketball with SMAP. Aiba became a Johnny's Jr. in August 1996 at the age of 13, not wanting to be an idol, but just to play basketball.

His stage acting began in 1997 with Stand By Me as Gordie and Kyo to Kyo. In 2005, Aiba took up the lead role of Keiji Takashima (高島 啓治), a naive but honest station attendant living in a world after a World War III nuclear war, in Tsubame no Iru Eki (燕のいる駅, A Station with Swallows).

Aiba portrayed Adam, a shy young man with a heart defect, in Wasurerarenai Hito (忘れられない人, Unforgettable Person). It was the first stage adaptation of the 1993 film Untamed Heart in 2007. In early 2008, Aiba was given the lead role of Colin Briggs in a stage play called Greenfingers. He took on the lead role for Kimi to Miru Sen no Yume (君と見る千の夢, The Thousand Dreams I Dream With You), which ran from May 5 to May 24, 2010. He portrayed a young man hovering between life and death due to a violent traffic accident.

The voice work he did for one of his animal shows was a snippet in the beginning of one episode, then became the ending credits scene: This is Katsushika Ward pre-faction departure place No. 248 (January 6, 2002, Fuji Television).

Oh wait...  the other pictures I grabbed that were not included in this article:

I learned so much about this man while researching for this article,  and I am glad that I got the opportunity to write this article. He is no longer "the other guy in Arashi" to me. His tall, quiet, goofy, smiling idol persona has grown on me. Looking forward to seeing where his career takes him next.
