One thing to note about Iwatsuki is that it's hard to get his "sound," so to speak, because he frequently collaborated with other Natsume sound team members, most notably Iku Mizutani and Haruo Ohashi. However, four out of his six chiptune works were solo ventures, so from these we can get some insight into the man's usual style.

We can already see some similarities in the structure of the songs. Each loop has three basic sections: an intro, main body which ends in an upward sequence, and high conclusion. Both songs also have a driving bassline and percussion too. We'll see the tripartite structure and backbone in the next two co-composed samples from the SNES.

I've been hand-picking tracks on purpose to reinforce the first sentence in the post, that Iwatsuki is the master of the generic beat 'em up track. All four games featured so far are side-scrolling/platforming beat 'em ups. More important, though, is how similar these songs are; the games Iwatsuki has worked on are chock full of songs just like these that grab you and yell out, "Beat up enemies to me!"
However, what I like about these soundtracks are just how eminently listenable they are. "Generic" does not automatically mean a song is bad; despite the four songs I picked being mostly interchangeable with one another (discounting the synth qualities of the three platforms), each track has its own decent melody and hooks, variety, and development. If these types of tracks are up your alley, then you should definitely check Iwatsuki out, because there are lots more tracks just like these.
Now that I've talked about how his music is all the same, let's look about some of his work that actually does sound different!

So in addition to beat 'em up tracks, we also have almost Kirby-like ^___^ness, almost RPG dungeonness, and almost technocrapness. I used "almost" and "-ness" in all three of those "genres" because each track does manage to still retain a little bit of the Iwatsuki flavor. Staff Roll and Haunted House have pumpin' basslines, and Airport still gets you ready to kick the crap out of something. Iwatsuki has a consistent style in his works that just rocks.
