To celebrate Tsuburaya Imagination’s 1 Year anniversary, The Final Odyssey and the Ultra 8 Brothers films, will be available soon on the platform! (details in comments)
One of the Franchise’s Biggest Movies, and one of the only times where Daigo those the grunts of Tiga instead of Machi.
Man if only we fould’ve gotten Final Odyssey on the Mill Creek set.
The following dates for both highly demanded films are as follows:
Premium Plan (21,780 yen annually including tax): March 1st
Standard Plan (550 yen per month including tax): April 1st
In addition, any people who are new or returning to the service can register the limited time coupon code to receive the standard plan free (majority of ultra shows but not non-ultra stuff) from Feburary 10th to Feburary 28th (which is also the length of the plan)!

*The code can only be redeemed on browser, not the app (for some reason) and cannot be used for those who are currently running standard or premium plans.
*You will need a Tsuburaya account and a D account (dアカウント) to access the service. It cannot be applied through docomo services.
*After the free period ends, you will be billed on March 1st. Cards are accepted but D-Payment is currently unacceptable.
Will the ending themes be changed due to Johnny Boy?
Superior 8 Ultra Brothers and Tiga: Final Odyssey are hands down the 2 very best Ultraman movies ever made, change my mind 
Ah, yes the ones with Daigo
Tsubaraya is definetely flexing
For a minute I thought this was gonna be on the TsuPro yt page and got super excited 
About Tsuburaya Imagination,
probably many have asked this before, but is watching on Tsuburaya Imagination free or paid like other streaming platforms?
I think things will be unchanged since they got Tiga with Take Me Higher intact. But you never know with Johnny.
The Tsuburaya Imagination distribution of Ultraman Tiga is uncut and unedited, unlike the milcreek dvd where they replace Take Me Higher opening and other BGM derived from Take Me Higher with other music, TsubuImagination have everything intact.
It’s really unfortunate how those 2 movies aren’t on TsuPro’s youtube channel yet but don’t worry tho cuz you can find them easily in youtube uploaded within other channels anyway dude! 
Okay, this is gonna be a long one but stick with me…
Imagination is mainly a paid service but you can watch stuff for free, albeit very limited overall such as no written articles to read (i.e rise of ultraman JP translation) and not being able to take place in live events such as stage shows until it has ended.
The service has mainly Ultra stuff but also has other projects that TsuPro worked in the past.
There are two paid options available: Standard and premium (see my other comment on pricing)
Standard plan is where you can watch and read pretty much all of the Ultraman-related media that the service has. However some written stuff and non-ultra media (such as Izenborg and the OG Gridman series) aren’t available. You can partake in live events but you may only be able to get some exclusive items.
Premium is a pricier, annual plan but you get everything both Ultraman and non-ultra related. For live events, you can get pretty much all of the event goods and even a earlier access to tickets. Not only that, but you can also access content earlier than the standard plan (i.e the two Tiga films I posted about)
Imagination Exclusive content such as Sevenger fight and UGF:TDC can be seen regardless of which PAID plan you are on.
Unfortunately, as its mainly a Japanese service, you’ll be needing a VPN if you want to access the content.
I know this went pretty long, but I do hope this answers your question!
As long as those uploads are not taken down. There’s a youtube channel by a chinese user who have uploaded all Ultraman series complete with all movies and special from bluray and dvd source. But the channel has been taken down last september
There’s actually a channel over at youtube who I watch majority of the Ultra shows on and his name is Avanaf and he has everything over there like the entirety of both the Showa and Heisei era shows and movies so i’m just glad that his channel hasn’t been taken down from copyright just yet so thank god for that!
