First time I saw this film must have been around 1987, on German TV I remember. "Die Familie mit dem umgekehrten Düsenantrieb". Either this one or 'Tampopo', which I saw around the same time, are the first Japanese films I even saw.
I was gobsmacked by this one. Loved every minute of it. It's totally zany. It's a wonderful satire on 'booming Japan' in the 1980's. I particularly liked the role of the mother played by Mitsuko Baishô. I would say in the film, she's a kind of Japanse Teri Garr. Very subtle satire next to the outrageous things going on. The rest of the roles are filled perfectly which makes this a little gem. Of course, being 17 when I first saw it, Yûki Kudô did make an impression. Not sure though if this film would work for younger audiences in 2017, you probably have to know the zeitgeist of the 1980's a bit.
Have been trying to get this film on DVD or Blue-Ray for YEARS and finally managed to find a copy on German Amazon. It belongs to my personal list of 'cult-films'.
10 out of 10 would be a bit off, the film is good and very entertaining but not a masterpiece, but I give it 9 for pure personal reasons.
