His family consists of a father, a mother named Hiromi, a younger brother named Ryuusei, and a dog named JAM-chan. His father wanted to name him Ikuta Tamegorou, but his mother changed it to Toma because it was easier to say. He used to be called Toma, Touma, or Toma-chan by his family and friends. Younger juniors in the agency used to call him Toma-san and that morphed to Tomasu. This name was used to be his “trademark” as he hosted a show named Meitantei Tomasu in the Shounen Club program.

* He used to be in a variety show for kids, then was offered to enter Johnny’s Jimusho (Johnny's Entertainment) at the age of twelve, and started to participate under Johnny's Jr.
* Soon he was grouped with some members of the current J-pop unit, Arashi. Together, they formed a group called M.A.I.N. (which stands for each member’s family name: Matsumoto, Aiba, Ikuta, and Ninomiya).
* After M.A.I.N., Toma was grouped again with a Jr. unit named B.I.G. (Bad Image Generation) along with ten other popular Juniors of that time. This is the time when he met Tomohisa Yamashita (NEWS), or YamaPi, with whom he is still very good friends. Soon, B.I.G. was reduced to just Toma and YamaPi.
* In 2002, upon Tackey & Tsubasa’s graduation from Johnny's Jr., the group 4Tops was formed in order to replace them as leaders. The group consisted of 4 members: Ikuta, YamaPi, Jun Hasegawa and Shunsuke Kazama. Their job was to host Shounen Club and to lead the Johnny's Jr.
* April 2003, NEWS was formed with YamaPi as the leader. This group debuted along with 9 members from Johnny’s Jr. so 4Tops became 3Tops, and not so long after that, they disbanded, and each member started working solo.
* As of June 2006, he became part of an unofficial group within Johnny's Entertainment called "No Border", which also includes YamaPi, Jun Matsumoto, Shingo Murakami (Kanjani8), Atsuhiro Satou (former Hikaru Genji), Koichi Domoto (Kinki Kids), Tatsuya Yamaguchi (TOKIO), and Hideaki Takizawa (Tackey & Tsubasa). It was formed when the 8 members from different JE groups met up for dinner and decided to name themselves "NO BORDER". They are known to interact freely, bypassing the senpai-kouhai relationships normally formed by Johnny's members. There is a 7-part round-robin on their J-webs about the formation of the group. Each member has a specific colour - White, Black, Red, Pink, Purple, Gold, Blue, and Grey. However, who holds which colour is still unknown.
* Ikuta has already participated in numerous performances of Musical Stage Plays. One of his biggest breakthrough was his first leading role in the Shinkansen*NEXUS stageplay "Cat in the Red Boots", as TOMA-sama. Furthermore, it's been decided that in October 2007, he will cast in a new stage play titled, "The Two Gentlemen of Verona" which will be held in Osaka and Tokyo.
* Ikuta had his own temporary J-web named Tomagoto (Toma’s words) where he could write his thoughts and experiences, but because it was temporary, it eventually came to an end. However, after a number of fan requests, they continued the series again and it was named “Tomagoto Returns” but read as “Tomagoto Hyper”. Being temporary, it ended last February 28, 2007. He also has a J-web collaboration with Musical Academy called KinToMA (Kindan no Tomagoto) and last June 7, 2007 they decided to continue Tomagoto, under the name "Tomagoto NEO".
* Ikuta also has his own corner on Wink Up Magazine titled “Ikuta Toma no Ikita Kotoba”. On this corner he used to talk about “heart touching” things, and he often writes about his mom.
* Ikuta was the one who came up with the name NO BORDER.
* He ranked no. 2 after Shun Oguri on Oricon survey conducted from High School girls "which celebrity they would want as a boyfriend" 
* He is a big fan of Backstreet Boys. He even begged Music Station’s staff to let him in the studio to watch Backstreet Boys rehearse.
* He used to call his mother “Okaa-chan” when he was little, but after being teased by M.A.I.N’s members, he called her “Okaa-san”.
* Toma is also a fan of X Japan, especially of popular guitarist Hideto Matsumoto. He once talked on the phone with Subaru Shibutani (Kanjani8) for an hour, just discussing X-Japan.
* He and his younger brother Ryuusei are fans of GLAY and they attend every single concert during his spare time.
* He and Shun Oguri had to kiss 12 times for the drama, Hanazakari No Kimitachi E.
* He and Oguri were the ones who came up with the nickname Horikitty for Maki Horikita who they acted together on Hanazakari no Kimitachi E.
* He and Eiji Wentz used to be in a kids band named "Strawberry Parfait", but when they got an offer to enter Johnny's, only Toma accepted.
