Japanese media reports that Japanese OEMs are planning to increase vehicle production in the first quarter of 2014 ahead of a domestic tax change planned for April.

Reports suggest that Japanese automakers anticipate a big increase in car sales in Japan before a sales tax increase in April.

Toyota will increase domestic output in January-March by about 10%, the Nikkei business daily reported.

In January, Honda will operate two of its domestic plants two days longer than originally scheduled to meet demand for one of its smaller models, the Nikkei said.

The Nikkei said that Japan will raise its 5% sales tax to 8% in April to help pay for rising healthcare costs. The tax increase has prompted consumers to bring forward purchases of big-ticket items such as cars.
