In Japan there is concern that the temple - traditional place of worship for Buddhists across the country - is under threat, particularly in rural areas where the population is aging and the younger generation are leaving for big cities, as Chris Hogg discovered

Shinkyo Toyoma has three sons and they are all mad keen on judo.

The eldest is 18, a big lad, and he is grimacing at me. No teenager likes to be shown off to guests.

Mr Toyoma takes no notice. He is proud of his three boys. But he is also worried about them.

One day one of them is going to have to take over the family business and none of them is keen.

He tells me that, when he was 18, he did not want to inherit the family firm either.

He rebelled at first but then, as now, there was a lot of expectation in the small community where they live that he would follow his father's example.
