What's a toku?
Tokusatsu is a Japanese term that means "special filming". As a genre it refers to pretty much any live-action production that makes extensive use of special effects. In the literal sense, anything from Wonder Woman to Doctor Who could be considered tokusatsu but, much like "anime", it is used colloquially in English to refer specifically to shows and movies of Japanese origin or adapted from them.
What's on?
Kamen Rider Fourze
Strange things are afoot at Amanogawa High School. Mysterious monsters called Zodiarts are wreaking havoc across the schoolgrounds. Gentaro Kisaragi is a delinquent who's just arrived at the school; an outgoing guy who isn't above beating his friendship into you. Teaming up with his space freak friend and a resistant loner, Gentaro becomes Kamen Rider Fourze in his quest to uncover the mystery of the Zodiarts and make friends with everybody in the school. Along for the rider are the members of the school's newly formed Kamen Rider Club. It's space time!
Tokumei Sentai Go-Busters
13 years ago, an evil energy being called Messiah was cast into subspace when it attempted to hijack the world's energy supplies and create a world for machines. Now his minions, lead by the Europhile Enter, are trying to steal energy in an attempt to revive him. Three survivors of the event 13 years ago come together to become the Go-Busters, a force designed to fend off Messiah's Vagras and discard as many pairs of sunglasses as possible. Let's morphin'!
Hikounin Sentai Akibaranger
In the electric town Akihabara a 29 year old Super Sentai fan/moe anime enthusiast, a cosplayer and a would-be martial artist are brought together to become the unofficial squadron Akibaranger. Utilising the powers of delusion, they become the Akibarangers in an effort to fend off a mysterious threat and maybe become an officially recognised Sentai along the way.
Ultraman Retsuden
More a franchise retrospective than a truly new series, Ultraman Retsuden seems to be largely comprised of episodes from previous entries in the Ultra series.
Power Rangers Super Samurai
The second half-season since the franchise's return to its original owners, Power Rangers Super Samurai continues the trend of basically being translated Samurai Sentai Shinkenger scripts with some leftover Bulk and Skull scenes randomly stapled in.
What's coming up?
The big release on the horizon is Kamen Rider x Super Sentai: Super Hero War. An inter-franchise crossover pitting the Kamen Riders, lead by the fabulous pink man himself Dickeido, against the Super Sentai, headed up by Gokai Red Captain Marvelous. Naturally, in the usual Super Sentai VS movie style they're likely to wind up working together against some larger threat after either realising that it was all a misunderstanding or revealing that they were pretending all along in order to trick the enemy.
What else is out there?
Garo series
Do you need mature toku for mature viewers such as yourself? Then Garo is the show for you. I haven't seen either of these shows yet, but my understanding is that their standout features are basically "omg tits and blood!"
Metal Heroes series
Running for 17 years, the Metal Heroes series featured 17 different shows. Generally using a technological motif, a handful of these shows were adapted as VR Troopers and Big Bad Beetleborgs at the height of the Power Rangers phenomenon. A popular hero from this series, Space Sheriff Gavan, was recently featured in a vs. movie with the Pirate Sentai Gokaiger.
Tomica Heroes series
Comprised of Rescue Force and Rescue Fire, the Tomica Heroes series ran for two years. Skewing a little lower demographically than even Super Sentai, the Tomica Heroes shows are nevertheless fun watches that feature great CGI and consummate boss Hiroshi Fujioka.
Monkey
Popular in the UK and Australia, Monkey is a retelling of the Journey to the West story. Featuring a funky soundtrack, fun fights, the odd bit of Buddhist philosophy and an over-the-top dub, Monkey is a true classic
