Japan has one of the lowest crime rates in the developed world - for a visitor, it feels like a place where everyone follows the rules.

But behind this reputation lies an extraordinary statistic - ninety nine percent of those accused of breaking laws here are found guilty.

Most of those convicted have confessed to the police. But a recent miscarriage of justice has sparked a debate about the methods police use to obtain confessions.

The BBC's Tokyo correspondent, Chris Hogg, reports on the case of a group of business people in a small town in southern Japan who were wrongly accused of involvement in a vote-buying scandal.

The way they were treated, and the way some of them were persuaded to confess, has prompted the Japanese authorities to push for a change in the law.

But will this change prevent a similar miscarriage of justice in future?
