Ahh, yes. I forgot about that. Good find.

Here is one that is from the metal heroes:
- It is most likely the reason Winspector did not follow the typical good guy defeats bad guy formula and was set as a special rescue team is because there was a serial killing in Saitama at the time and anime and toku were the subject of criticism regarding fictional violence.

- Juspion actor Hikaru Kurosaki was the lead of a manga to live action adaptation movie called Kotaro Makaritohru where he played the titular Kotaro and Kenji Ohba of Gavan fame played the antagonist, prior to Juspion he was a guest character for two episodes in Bioman

This....this would've been soooo much better!!

No doubt. And still Narutaki walks the Earth saying what he says best.
They should have kept Decade simple and short instead of not knowing what to do if they were not gonna use the idea Shin Henshin shared with us above.

Hmm..I am find some of similarities between Boukengers and Kamen Rider Birth:

1.Their helmet design is very similar especially the visors and the mouthpiece part.

2.Some of their weapons also has same weapon-types such as:

a. Drill Weapons (GoGo Drill with Drill Arm)
b. Crane Weapons (GoGo Crane with Crane Arm)
c. Shovel Weapons (GoGo Shovel with Shovel Arm)
d. Wing Jetpacks (GoGo Jet in Ultimate Daibouken Formation and a Cutter Wing on Birth's back)

3. Both Boukengers and Kamen Rider Birth collect special items. Boukenger collect Precious and Kamen Rider Birth collect Cell Medals.

I think Kamen Rider Birth has some inspiration from Boukengers.

Trivia for y'all

- Actor Shion Tsuchiya had his break in toku as young Isshu/Kuwaga Raiger in Hurricanger before appearing as JK in Kamen Rider Fourze

- Kyosuke Jinnai/Red Racer is known to be popular towards villainesses, first being Zonette in Carranger the next being Insarn in Gokaiger

- Yuuji Kishi who played Kyosuke/Red Racer played three Les Miserable characters in the Japanese production of Les Miserable, first as Brujon from 2003 ~ 2006, then Enjolras from 2005 ~ 2007, and in 2015 Javert(he is scheduled to reprise this role this year from May 21st to October)

- Before becoming Conductor/ToQ7, veteran comedian Tsutomu Sekine was a truck driver in episode 57 of Goranger

- The following toku alumni have appeared in the Do Not Laugh 24 Hours Specials of the Japanese comedy show Gaki No Tsukai Ya Arahende at least once:
Arthur Kuroda: Itsuro Takamizawa/Kamen Rider Verde from Kamen Rider Ryuki Special
Toori Matsuzaka: Takeru Shiba/Shinken Red from Shinkenger
Rin Takanashi: Mako Shiraishi/Shinken Pink from Shinkenger
Tsutomu Sekine: Conductor, ToQ7 from ToQger
Tomomitsu Yamaguchi: DJ Sagara from Kamen Rider Gaim
Itsuji Itao: Kamen Rider Fifteen from Showa Rider VS Heisei Rider movie

I love the Do Not Laugh specials.
I gotta keep a sharp eye next time I watch one to see if I can catch them.

Do you know which ones they appear in, and if those particular episodes have been subbed?

I looked up the Japanese wikipedia page for this. Matsuzaka's was the most recent in 2016 as a character from one of his dramas, Takanashi was 2015 also as a character from one of her dramas(funny thing, both are mystery drama characters), Yamaguchi was 2011 as Rickson Gracie(yes, THE RICKSON GRACIE), and Kuroda was 2010 as a "handsome spy". Itao and Sekine appears regularly so hard to pinpoint those two.

Matsuzaka: Do Not Laugh Scientist
Takanashi: Do Not Laugh Detective
Yamaguchi: Do Not Laugh Airport
Kuroda: Do Not Laugh Spy

I think those 4 have been subbed, so I gotta check them out and keep a keen eye!

As for Itao and Sekine, I never watched ToQger, and the Heisei vs Showa movie didn't leave an impact on me, so I probably would never catch them unless explicitly pointed out to me, despite them apparently being regulars.
