So that's the "Under the Velvet Sky" one?
Back then you could still sort of tell what he was singing about.
4AnonymousNov 14, 2026 12:09
I wonder if Kiyoharu was influenced by Blankey Jet City at all?
5AnonymousNov 14, 2026 12:10
Re: #4
Blankey Jet City was too much of a genius, totally one-of-a-kind.
I've never once thought they sounded like Kiyoharu.

Re: #4
They're actually both from the Chukyo region (greater Nagoya area).
6AnonymousNov 14, 2026 12:12
Why did L'Arc~en~Ciel get to perform at Kohaku (NHK's big New Year's Eve song show) while Kuroyume never did?
7AnonymousNov 14, 2026 12:12
It was such a crappy era, where half-baked wannabe-thug types got hyped up as cool.
9AnonymousNov 14, 2026 12:14
The music video for 'Shounen' was as cool as something by Ozaki Yutaka, wasn't it?
10AnonymousNov 14, 2026 12:15
Re: #6
L'Arc~en~Ciel is a genuine collective of geniuses.
They're not even on the same level, let alone comparable.
15AnonymousNov 14, 2026 12:20
Re: #10
A clip of L'Arc~en~Ciel's band rehearsal showed up in my recommendations and I cracked up.
Hyde is speaking in this barely-there voice like he's facing a public execution, going "I think it'd be better if we did ~ this way,"
and this guy named Tetsu just fires back a single condescending "yeah, sure" in response.
Such a tense, cutthroat vibe — if I were actually in that band my stomach would be in knots.
21AnonymousNov 14, 2026 12:26
Re: #15
I heard they begged Hyde, who was in a different band at the time, to come join.
Probably that same Tetsu guy you mentioned —
apparently whoever's acting as the leader kept inviting him because he was just too good-looking to pass up.

Re: #15
It's wild that the band's most popular, most famous, best-looking frontman is more deferential to the other members than anyone.
It's like Freddie Mercury bowing and scraping to Brian May and Roger Taylor.
Just bizarre lol
11AnonymousNov 14, 2026 12:16
Kiyoharu hasn't lost a step at all.
He can actually hit higher notes now than he could back in the day.
57AnonymousNov 14, 2026 13:26
Re: #11
Well, the looks are, uh…
12AnonymousNov 14, 2026 12:17
Kuroyume has way too much "chuuni" (edgy-middle-schooler) energy, it's rough to listen to now.
13AnonymousNov 14, 2026 12:19
The pre-chorus (B-melo) is so good that the melody flows seamlessly from the intro all the way through to the chorus.
14AnonymousNov 14, 2026 12:20
Producer Akira Isoyama really was something, assembling a cast of people who'd all go on to become huge stars.
17AnonymousNov 14, 2026 12:25
If it had been Blankey Jet City, they'd have probably gotten pissed off and bailed the second someone told them to "make it catchier" lol
27AnonymousNov 14, 2026 12:30
Re: #17
Their theme song for Re: #19, "Dandelion," is exactly that case, and they didn't quit over it.
26AnonymousNov 14, 2026 12:30
As someone who remembers back then, it's unbelievable how close Kiyoharu and Hitoki are these days.
There was a stretch where they wouldn't even make eye contact — playing shows with zero conversation, not even a greeting.
30AnonymousNov 14, 2026 12:34
Just a bunch of nonsensical ◯✕A%-na??-no□/~ gibberish
31AnonymousNov 14, 2026 12:39
I thought this was about New Japan Pro-Wrestling for a second.
IWGP (same acronym as their heavyweight title)
32AnonymousNov 14, 2026 12:40
Kubozuka had already done okay for himself with stuff like GTO, but this is what really made him blow up.
35AnonymousNov 14, 2026 12:43
The very first live show I ever went to was Kuroyume at Kousei Nenkin Kaikan.
Kiyoharu was totally in the zone and gave us encore after encore.
Brings back memories.
36AnonymousNov 14, 2026 12:44
Not sure if the tall member actually lived in my neighborhood, but I used to see him walking around alone looking kind of sad all the time.
38AnonymousNov 14, 2026 12:48
Band theme songs from that era are just great.
A bit earlier than this, but stuff like Rebecca's "Friends" or Dreams Come True's "LOVE LOVE LOVE,"
"Tokyo Love Story"…
I could go on forever.
Seriously, there were tons of artists back then who could really sing a great song.
40AnonymousNov 14, 2026 12:49
I'm curious what kind of song would've come out of it if they'd asked Blankey Jet City instead.
Their last single, "SATURDAY NIGHT," might've fit the bill (though for some reason it ended up as the ending theme for HEY!HEY!HEY! instead…).

Re: #40
Not bad, but I'm just not a fan of his voice.
41AnonymousNov 14, 2026 12:49
"That song did a lot for me" lol, that's the ONLY song you've got, man lol
42AnonymousNov 14, 2026 12:51
Ikebukuro's got those color gangs, too scary to go near.
43AnonymousNov 14, 2026 12:51
I wonder if Makoto's still running around out there in the novels.

He said he finally figured out the formula for writing a hit song.
Though these days he seems like a total has-been.
59AnonymousNov 14, 2026 13:39
This is what happens when all you do when you're young is act cool.
You young guys should take this as a cautionary tale and watch yourselves.

Don't worry! I'm just as much of an old man as you are.

Kiyoharu once praised Blankey Jet City, The Hi-Lowdowns, and CASCADE in a magazine interview.

What a lame lineup lol

Background and Key Points of This Discussion

‘Ikebukuro West Gate Park’ is a drama based on the novels by Ira Ishida that aired on TBS in 2000, and it’s also a work often credited to the skill of producer Akira Isoyama, who cast future stars like Yosuke Kubozuka and Tomoya Nagase early in their careers. The theme song was “Under the Velvet Sky” by SADS (the band Kiyoharu formed after Kuroyume broke up), and as noted in the thread, there’s testimony that it was commonly heard as a ringtone around Ikebukuro’s shopping district at the time. The thread’s focus on this one song’s fame led some posters to frame Kiyoharu as a “one-hit wonder,” but it’s worth noting he’s had a long career spanning Kuroyume, SADS, and solo work, so it’s easy to conflate praise for this one piece of work with an assessment of his entire career. The conversation also branched out into anecdotes about contemporaries Blankey Jet City and L’Arc~en~Ciel — a tangent driven by nostalgia for the ’90s band scene in general rather than anything to do with IWGP itself, and it’s best read as a separate strand of reaction distinct from the article’s actual subject: the Kiyoharu–Kubozuka conversation.
