So I've taken some time to think. And...I think it would have to GokaiGreen. Doc was just a funny fighter.

Can't complain. :)

I actually would like to see one. We have recently had a member or two who are high school students such as Kyoryu Green, Shironinger, and Kininger but not the whole team.
And hey, who knows. Maybe we can do a Turboranger/Megaranger/Next High School Team mash-up. :)

So question for those who have visited Japan or live there.
Have you visited the tokusatsu bar run by either Ei Hamura (Shoji/Tenma Ranger) or Masaru Shishido(Goro/Oh Red)?
They each have their own bar themed after tokusatsu and I am curious if anyone has been to either one or both.

What your ideas for the 2020's season ?

I'm all sorts of okay with that Mash-Up. And as for the bars...well I've never been to Japan so I do plan on going one day and when I go I'll be sure to hit them both up and try to write a review of them for you all.

Like everyone else I want that Olympic or sport themed Sentai since Japan is hosting the Olympics in 2020.

I wouldn't. The Olympics guards their logo and trademarks like a hawk. I honestly think they would actively fight to prevent the series from being uploaded :lol

At the very least a sports theme would be cool. Have the helmets based on American football helmets and then the rest on other sports

A Sports Sentai team would be cool. I like each Ranger is based on a sport (Baseball, American Football, Basketball and a few others).

Oh I'm already spriting out an idea XD

I have been to Mr. Hamura's bar quite a lot of times in my last week in Tokyo and it was absolutely amazing. Mr. Hamura is a really nice guy and his co-worker was a very loveable girl around my age named Miyuu. It's a bit expensive because you have to pay a fee for the bar itself, but I found it to be worth the money. The decor is really nice, it's full of toys, books, posters and autographs and photos of the actors who came there. There's also a TV on which we would also watch toku from time to time (we watched Gosei vs. Shinken, a bit of Kamen Rider Amazons and some eps of Dairanger when I was there). The room itself is very small, there's a few seats around the bar and a sofa with some seats. Quite cozy ;)
The drinks on the menu were mostly created by actors (including suit actors) and are character- or show-themed.
You may meet some of the actors, writers or directors there, but it says in the rules (in the menu), that you can't just randomly chat them up or talk about it too much later. If they feel like chatting (as in, a conversation between all the guests and staff develops or they directly adress you), it's okay, but it's basically a "don't bother them" rule because they come there to relax. Photos of the interior are also not allowed (you may take photos of your drinks and food, though).
I was also there when they had the "Kirin bar" event, which was a night when Mr. Tsuchiya (Kirinranger) would be in charge. Or rather, entertain the guests xD You had to reserve a seat and could stay for 2 or 3 hours (I think it was around 1500 Yen that night...). You could by T-Shirts or get signed polaroids and while Mr. Hamura and Miyuu took care of the bar, Mr. Tsuchiya would go around and chat with the customers. They offered special drinks and snacks too :)

I would recommend speaking some Japanese though, because, while they are trying to learn it, none of the people there speak English too well.

While I didn't visit any other bars, I did have dinner at RedMask's Ramen shop. Since at some point I was the only customer, we also talked a bit. It's a bit hard to find (most of the bars and restaurants are in rather quiet parts of the cities, not too many tourist around and very small), but not to far from the next metro station.

I heard that MegaRed also opened a Yakiniku shop in Shizuoka, were I lived, but sadly it was late summer and I didn't get the news before I left. That's on my bucket list for when I come back :)
