Yes he have that hairstyle the entire series

Another question. Are there any shows that have episodes that take place in theme parks? I know Ghost does, but I haven't seen much else Rider.

Pretty sure Skyrider and maybe Stronger did. Think one showed up in Agito as well. There's probably more, not super sure though.

Ryuki has a scene in an amusement park which has the main character following a secondary character and they argue about things while they're using the rides and attractions, and Kabuto has an action scene in like episode 3 where they fight in a park, on top of a rollercoaster and inside a carousel and stuff.

Double has a scene in an amusement park as well, I think it's the debut episode of Accel, and in OOO the main character has to disarm bombs in an amusement park which some bad guy set there, I think. If I recall it correctly it’s the debut episode, or one of the two-part story at least, of the PuToTyra form.

These are the ones I remember right now but there are much more probably.

Besides the ones mentioned, I remember both Black RX and Faiz having amusement park episodes. Faiz's takes place near the end of the show and is, naturally, really fucking dark.

There's also an episode of Drive where they try to disarm bombs in an amusement park.

Or rather THAT amusement park, because it's always the same xD

This isn't the amusement park that people are talking about (looks like the outside of a sports arena), but do these four scenes also have the same location?

1. Kamen Rider W (Cyclone Joker)
2. Kamen Rider OOO (TaToBa)
3. Captain Marvelous and Fourze encounter
4. Go-Busters first battle

I love how once you've watched enough toku you start to notice all the suspiciously similar locations. Like that one tunnel people always walk into and get attacked by a monster. You know the one.

Oh, that's actually in front of the Tokyo Dome. I think the scenes you mentioned should have all been filmed there, but I haven't been there yet, so I can't say it for sure. If I get the chance to go, I might be able to confirm it.

Actually, it's not just Toku. It's basically all Tokyo -based live action dramas and movies.

I feel like Sentai uses the same cliff to fight in front of (at least the older series)
