Tokyo LIve: January trade data showed an increase in Japanese exports of 17%, the largest increase in four years. At the same time the cost of imports fell sharply due to lower fuel costs and the Nikkei 225 average reached a 15-year high in trading this week. Now we just need to get Mrs Watanabe out shopping, get more immigrants to come here to work and get Mr Watanabe to make more babies with Mrs Watanabe.
