Rachman on Japan. Snuggling Ifbot anyone?

Of course, Japan has its problems. Its average age is rising steadily and its population is shrinking. One in five Japanese is over 65. The Democrats have promised to raise pensions and payments to parents – and to cut taxes. It is hard to see how the sums add up. While the US and the UK worry that their public-sector debts could hit 80 per cent of gross domestic product, Japan’s debt is heading for 200 per cent.

Some of its efforts to deal with an ageing society are positively unnerving. The country has led the world in developing robots as companions for the elderly. These include a “snuggling Ifbot” that, according to press reports, “lives in an astronaut suit, chats about the weather, sings and plays games”.

It is best not to laugh. As the US and Europe struggle to come to terms with the aftermath of a bubble economy, rising public debt and the retirement of the baby-boom generation, they should look to Japan with respect. It may be the future.
