Original Article
[Note: This interview was conducted for the release of Vocalolegend, a CD which Hachi submitted Rakshasa to.]
  • I'm playing by myself around the clock. (laughs)
So your PVs are all your own work too, but you started out drawing with a mouse...
Hachi: I didn't yet have a tablet or a scanner, so I figured I'd just use what I had. Well, I still don't have a tablet, but I can at least scan in drawings.
Creating everything with a mouse must have taken a lot of time, right?
Hachi: Nah, it takes more now.
Is that because you draw rough drafts and improve them through trial and error?
Hachi: No, I hardly ever draw rough versions. Drawing on top of something I've already drawn once? I'd hate that.
Truly a genius.
Hachi: No, no, no. (laughs)
Now, about your most popular work, "Close and Open, the Rakshasa and the Corpse." Users tend to wonder about the peculiar art and the deep significance of the lyrics.
Hachi: Everybody imagines all sorts of things. That people would read so deeply into it really surprises me. I just wrote that song with a theme of everyday life, but some people interpret it as being about the services of certain women at night.
That's a long way off from everyday life. (laughs)
Hachi: But it makes me happy. Because it means people like it enough that they'd think so much about it.
When you posted that song, did you expect to get so many views?
Hachi: No, I didn't think it'd get much publicity at all! In fact, I didn't think it'd get anywhere, much less a million... I couldn't have imagined it. I guess I was too busy thinking it'd be nice if it got 10,000. Not that it'd go so much further...
Were you thinking of making it Japanese-style from the start?
Hachi: No, nothing of the sort. I still don't have any idea why I made it like that.
When you're writing a song, how do you usually conceptualize it?
Hachi: This isn't just limited to when I'm writing songs, but I have a kind of diorama in my head. From there, I work on introducing the pictures and the music... which kinda feels like playing with dolls or something. When I think of a character, they begin going about their business in my head. What kind of personality will they have? How will they act? I try to imagine these things, then spontaneously come to discover that a situation like this will lead to a song like this. The melody and lyrics pretty much follow from there. After that, I just need to output it.
So have you ever suddenly gotten a diorama forming while doing schoolwork?
Hachi: No, I can't think about anything else. (laughs) But yeah, that kind of playing on your own is pretty fun.
On that topic, are there any songs that you've had to particularly contemplate?
Hachi: Qualia, definitely. I mean, the PV took tons of time to make, and while the melody of the chorus had been in my head since years ago, giving it form took some thought.
  • I'm addicted to Vocaloid!
You play in a band. What parts do you play?
Hachi: Bass and vocals.
Though now deleted, you uploaded about 30 original songs you sang yourself.
Hachi: There were that many?
Yes. So why did you delete them?
Hachi: I'd put a lot into them, but listening to them again, it seemed like I couldn't understand them anymore, and I felt really ashamed. So I figured it was my duty to just delete them all already. (laughs)
And you began making songs sung by Hatsune Miku. Did you originally use Miku wanting female vocals?
Hachi: That was one reason, but the main one was that I had upgraded my PC. Until then, I'd been dealing with astoundingly terrible specs and could barely go on the internet, so I could hardly do anything. But when I got a new PC, all that changed, things were so much more agreeable. And feeling like I could do anything, I was introduced to digital music, figured I'd give it a shot, and bought Miku.
What did you think of Hatsune Miku?
Hachi: I always thought my songs would've been more suited to female vocals, so finally being able to have them that way made me happy.
Your songs get sung by a large variety of women. Have you listened to any of them?
Hachi: Yeah, I listen to them all the time.
Any singers in particular you like?
Hachi: It's not a woman, but I liked Sekihan singing Mrs. Pumpkin's Ridiculous Dream. He really mixed things up, but it didn't really get in the way of the song.
Would you want to write a song meant for human vocalists? And would you want anyone in particular to sing it?
Hachi: I have feelings that I want to sing, but Vocaloids don't have feelings at all. It may be a contradiction, but I really appreciate that they can express my own world views for me. So I really don't have any desire to sing now - I'm too addicted to Vocaloid! (laughs) But, still, people singing for me makes me really happy. I'm listening!
So far, you've only put out Hatsune Miku songs, but have you thought about any other Vocaloids?
Hachi: I want to try using Megurine Luka. Her English is supposed to be pretty good, so I thought I might check out her English pronunciation.
Any particular plans for her?
Hachi: No. I'm broke. (laughs)
  • As if I know how I should feel about changing situations.
With such popular songs, you must have had people asking you to contribute to collaboration CDs. What was your first contribution to a major CD?
Hachi: That was EXIT TUNES's Supernova.
When you were first talking about it, how did it feel?
Hachi: I was like, "really, me?" I felt that I stood alone, and thought that I maybe shouldn't go along. I didn't exactly have any "feelings" about it, though... Anyway, songmaking for me is like an extension of playing, so I figured it was fine. Even so, just like when I upload a song and have to pick out the thumbnail, I started to feel the tension rising. (laughs)
Afterward, you contributed "Close and Open, the Rakshasa and the Corpse" to the same EXIT TUNES's "Vocalolegend." Did you feel the same way then?
Hachi: I had more or less the same feelings of excitement, but... well, not quite. (laughs)
Both CDs were compilation albums with contributions from countless other Vocaloid producers. Do you listen to their songs?
Hachi: Oh, I definitely do. I really like Furukawa-P in particular. He just seems to have something other people don't.
Is there anyone you secretly consider a rival?
Hachi: Well, I don't have any reason for rivalries, but when I first started uploading Vocaloid songs, I was really worried about wowaka, who popped up at around the same time. He gave me a different feeling than other people did, too.
Worried that you were contemporaries? (laughs)
Hachi: Like you wouldn't believe! (laughs)
Lastly, a word for the fans.
Hachi: Thanks for always listening. I'll keep putting out songs, so I'd just appreciate your encouragement.
