Kirschblüten Hanami
This is the German mashup of UP! and LOST IN TRANSLATION that, like Aliens fighting Predators, prettymuch seemed inevitable to happen. You've got your old man who, upon losing his wife, is inspired to go on the exotic trip she always wanted to take; and once he gets to Japan, he forms a nice intergenerational friendship with a young woman going through the same emotional problems he is and they help each other by providing company and compassion.
The old man is Rudi, whose kids Karolin, Klaus, and Karl (like the Kardashians!

) are a bunch of ungrateful yuppie Struggling Background Artists. Karl took up his mum's fascination with Japan and lives there. So Rudi goes to stay with him. Karl acts like a complete shit and makes no time for his grieving father. In fact, he gets drunk and tells his father that he was a shitty father and a loser for working in the government, but Karl is one of those guys who blacks out so he doesn't remember any of that stuff the next day and is back to being somewhat polite to his father. Rudi gets bored snooping through his son's hentai collection and so he goes out to Tokyo's strip clubs. Rudi ultimately has a breakdown in a Tokyo rub 'n tug jerkoff parlour and decides to honour his dead wife in a way that doesn't involve Japanse snatch flying at his face.
Rudi then starts wearing his dead wife's clothes and wandering the streets of Tokyo, believing that in wearing her clothes, he is taking her on the trip with him. He quickly befriends a young homeless Japanese girl who likes old crossdressing German men, the two bond over losing loved ones and then simulate spring rolls by rolling themselves up in a giant tarp in a city park.
The two head out on a trek to see Mount Fuji, just like Rudi's dead wife always wanted to. Rudi puts on her clothes as well as Kabuki theatre makeup and does some Kabuki Tai Chi poses at the shore across from Mount Fuji and then
drops dead. This movie was fucking great.
