this film revolve as much around japanese culture a it do the life of one modern japanese family . physical contact be frown upon for those over 7 ( especially in public ) hence all that bow instead of hug even when you be close friend or relative . ballroom dance involves put your arm around someone else and that in public too . never the less ballroom dancing be ( on the quite ) immensely popular . people who do ballroom dancing in japan be view a bit like nudist in the west . many more would like to than do but be inhibit by the culture . a delightful family film and which any amateur dancer would enjoy for the dance sequence alone . i understand that it be more popular than titanic in japan . i guess the japanese be just like the rest of u they like to be hug too .
