Hitoaki Minami (南 人彰) - Shakkin Oh Official SEGA interviews have listed Super Daisenryaku (MD, 1989) and Advanced Daisenryaku (MD, 1991) as being designed by him. Both games credit a variation of this alias as such.
Chieko Aoki (青木 千恵子) - Otegami Chie (お手紙チエちゃん), Chiemushi Left Sega after getting married. Earned her nickname because she would always personally respond to fan letters.
Hiroto Saeki (佐伯 広人) - S2, Psyche Known to have directed Phantasy Star 2 and 3, which credit Psyche and S2 respectively.
Shiro Kinemura (杵村 史朗) - Rouly.S.Kine, Rouly The name is already a gimmie, plus he previously used the Twitter handle @rskine.
Toyonaka Ozaki (尾崎 豊中) - Toyo.Ozaki Confirmed on his personal site.
Kazunari Tsukamoto (塚本 一成) - Tsukapon, ??? Joined Sega in 1987, programmed Phantasy Star 3. Must have had at least one other alias?
Kazuyoshi Tsugawa (津川 一吉) - L.C. Has confirmed that Sorcerian (MD, 1990) was the first title he worked on.
Atsuhiko Nakamura (中村 篤彦) - Kyamura Lists Mercs (MD, 1991), Super Monaco GP II (MD, 1992), and Columns III (MD, 1993) as titles he worked on.
Hiroshi Momota (百田 浩司) - Momonga Momo Credited under his real name as early as 1987 (SMS Penguin Land). May have had another alias?
Kazuo Ikeda (池田 和男) - Ikepon, Dandadanikeda Credited as programmer on every Pro Striker game under different variations. Dandadanikeda is rather obvious, but several people worked on both MD Awoge and MD Teddy Boy Blues including this guy, Kazuyuki Hoshino, "Sunset", and "DSK".
Tomohiro Kondo (近藤 智宏) - Mu, Mu.Kondo Joined the consumer division in 1989 as a planner, and lists MD Shadow Dancer as his first work.
Kazuma Fujii (藤井 一馬) - K.Fuzzy, Fuzzy The name lines up (Fujii/Fuzzy), and he's credited together on several titles with Kazuo Ikeda, Junichi Tsuchiya, and Tetsuo Shinyu among others.
Ho-Gang Lee (李 浩康) - Hiroyasu Lee, Mr.Lee Name confirmed through a Japanese patent listing.
Junichi Tsuchiya (土屋 淳一) - J. Yatsuchi, Jun Tsu Chi, Jun Izy, J.T? Really, really obvious aliases here. Used several variations throughout the Pro Striker series, and J.Yatsuchi on MD Crying which shares several other staff.
Atsushi Seimiya (清宮 敦嗣) - Seishi Atsumiya Well-known and obvious alias. Still with Sega today.
Naohiro Warama (??) - Tarō Shizuoka (静岡 太郎), Shizuoka Taro Confirmed in interview.
Tsukasa Mori (森 司) - Sakatsu Rimo Simply the hiragana for his name spelled backwards (さかつりも).
Takako Kawaguchi (川口 貴子) - Choko (チョウコ), Choko Kawaguchi Confirmed by CRV as she used the twitter handle @choko_k
Tatsuo Matsuda (松田 達夫) - Healthy Tats, Dandy Matsu, Good Luck Matsuda Used his real name on SMS Penguin Land. Later went to work for Arc and Aspect, and today is a teacher at a game development school.
Yukinobu Arikawa (??) - Tombo Confirmed via interview.
Atsutoshi Takahashi (高橋 敦俊) - Tonsyun? Alternate reading of his given name.
Matsuhide Mizoguchi (??) - Mizoran?
Minoru Kanari (金成 貫) - Will Cane?
Noriyoshi Oba (大場 規勝) - The "Over", The Alive, Wanta/Wanter? Joined Sega in 1987, and was the project lead for the Super Shinobi and Streets of Rage series. Wanter/Wanta is yet unconfirmed. The studio name "Overworks" is a play on his name (Ōbaworks).
Koichi Nagata (永田 浩一) - Papa? There's a "Papa Koichi" credited on Alex Kidd in Miracle World (SMS, 1986). Nagata is said to have been the second-in-command of AM2 as late as 1990 (lines up with MD Rent-a-Hero) and later wound up in charge of CS4 which was created to do 32X software. Hard to discern as the credits to "Papa" are a mix of art, programming, and thanks.
Masaki Segawa (せがわ まさき) - Masa (雅), ??? Did character and monster design for Phantasy Star 3, along with the cover art. Now works as a manga artist. Did he ever actually *work* for Sega, or was he just a freelancer? Supposedly did the large ninja illustration when you lose the bonus game in AC Shinobi, and some of the story images in PS3 look like his work as well (confirmed: his signature can be clearly seen in the original paintings).
Kazuyuki Shibata (柴田 和幸) - Chaotic Kaz, Kaz the Werewolf, ??? Said in a 1993 interview that he worked on Phantasy Star 1 & 2, Pyramid Magic (!), and Surging Aura (!?) among others... Doesn't give a specific name he used.
Chie Yoshida (吉田 千恵) - Chie sama?, Chieriita? Well-known? Need to check this one...
Daisuke Yamamoto (山本 大輔) - DSK? Seems like a reasonable guess and the time-frame matches up, but I'm not 100% sure yet...
double check
Koki Sadamori (貞森 康毅) - 3712 SK Has specifically stated he joined Sega in 1986 working as an artist on Master System games, with Space Harrier being the first.
