  • A lot of times when he creates music, he calls himself "D.A..I." Most fans, however, just call him "Dai", "Nagao", "Mr. Nagao", or "Nagao-san".

  • What are some groups/artists that he has produced?
  • Some groups/artists he's produced include Sayaka Yamamoto (a member of the group "dream"), I-lulu, ZZ, Amasia Landscape and DAZZ FEED. He also helped produce moumoon's first two CDs and he helped SE7EN (a Korean artist) with several of his Japanese songs.

  • What is "Area404"?
  • This is Dai Nagao's music company.  Not too much is known about the company (and sadly, its official website went offline years ago), but I think Dai was the executive producer in the company. The company seemed to be independent (or "Indies") and not directly related to avex.

    I'm pretty sure Area404 did not have its own record label.  Every time I looked at the CD credits page for one of their artists (as an example, I'll use I-lulu), I saw a different record company listed (for I-lulu, their record company was "Get Over The Records").  So I think Dai Nagao outsourced the actual CD production to different companies, probably as a way to save money.

    In those same CD credits, Dai was usually listed as the "executive producer". And he was often listed as the main composer and/or arranger.

  • Why is it so hard to find pictures of this guy online?!!
  • This is a fantastic question. I've heard that in the early days of Do As Infinity, Dai Nagao wanted to stay out of the spotlight because he wanted to create music more than anything else (i.e., he left the TV commercials, interviews, and musical performances to Van and Ryo). And because of that, you'll rarely find any pictures of him.

    However...if you use Google Images (or more specifically, use Google Japan Images and enter his Japanese name, 長尾大), you'll see several nice pictures of him there.

  • Does Dai Nagao sing? Has he ever released a CD by himself?
  • As far as I can tell, no: Dai Nagao has never released a CD. But according to Jun Harada, he did sing "Yesterday & Today" ("Y&T") once...

    There was a party for the drama series that "Y&T" was being used in, but Van had to leave early.  And naturally, Dai took her place. (xD) If there's video footage of him singing, it's probably well-guarded by avex. (^^;)  I would LOVE to see it, wouldn't you?

  • Can Dai Nagao talk? I've never heard him talk before!
  • Since we rarely see this man, it's also rare to hear him talk. However...thanks to DAIForum user ainouta, you can actually hear Dai Nagao speak in this clip! (The clip came from "Do The Box", and was part of a special documentary. The clip also features an acoustic, street performance version of "Kokoro no Chizu".)

  • Is he single or married?
  • No one is really sure, because he's so secretive/mysterious!

    [ back to FAQ List ]


  • Why the heck is he so secretive/mysterious?!!
  • I explained part of this in Question #5. Bu he might also be "secretive" because he's...shady.  There was a rumor that he convinced one of his new artists to sleep with him and several problems happened as a result.  There's speculation that the "new artist" might be Aria Asia, who joined his Area404 label in 2007 or 2008.  You can read the entire article/forum thread here.

    Again, this is just a rumor so we don't know if it's true, and I seriously hope it's not.

  • Where can I buy Dai Nagao-related merchandise?
  • Be warned: since he composes a LOT of songs, he's "featured" on hundreds of CDs. If you want to buy some of these CDs, I highly suggest you use the "D.A.I Other Works" section as a guide (plus you can sample the songs there, and see which ones you like).

    There are tons of online stores that sell their merchandise. But I highly recommend YesAsia (their prices are low, their selection is large, and the shipping costs are low for people outside of Asia). You can also try CDJapan, Amazon and iTunes. If you want used items, there's an area in DAIForum called Aisle 3. Be sure to check it out! You can also go to eBay for used merchandise.

  • Where can I download [insert song here]?
  • I highly recommend you buy the CDs (or at least some of them). You can sample the songs on this site...but because there are so many songs, I didn't create a download section. Perhaps in the future, I'll make a download page and rotate the songs each month.
