A member of the Time Patrol finds out that there is a disturbance in Japan, 1570. While heading to that particular time and location to investigate, she is attacked and ends up stuck underground the Nohara residence at the end of the 20th century Japan. Having limited resources at hand, she is forced to ask for the help of the Nohara family. Together they go back in time and meet with a samurai named Fubuki-maru who believes that they are the legendary three persons and dog whom someone from her family would eventually meet in a crucial moment. The lonely samurai asks for their assistance in defeating the man that possesses strange magical powers, the sinister Unkokusai lord.
If you know ShinChan only through the Adult Swim television series, you might be surprised how great this movie is. I know I was.
In this movie, Shinchan and his family have to go back in time to help Fubukimaru save his (her?) sister from a deviant time traveler. Because of this, the movie deviates early on from the usual scatological humor of the tv show into an epic samurai action flick, with Shinchan mostly along for the ride.
Don't be turned off by the art style. The lack of details in the characters allows for a fluidity of animation that is
rarely seen in anime movies.The movie starts off slow, but the middle of the movie in particular is one extended castle-raid, which is one of the best action scene I've ever seen in anime.
And just as you think everything is over, a twist reveals that time travel is much more complicated than you think. The future scenes have zany architecture reminiscent of Tekkon Kinkreet. The sight of a fuedal castle turning into a battle robot is wacky and awesome at the same time.
The movie drags on rather long, and ShinChan's juvenile humour never did make me laugh that much (then again, I am not the target audience) , but if you liked Castle of Cagliostro, or Samurai swordfights, check out this movie. You will be pleasantly surprised.
