Hong Kong (CNN Business) Britain's dithering over Brexit has gone on too long for Sony.

The Japanese company said Wednesday that it would register its European business in Amsterdam, switching its legal base from London. It blamed uncertainty surrounding Britain's plans to leave the European Union.

The announcement underscores the fears over Brexit among top Japanese corporations, many of which are major investors in the UK economy.

Sony ( SNE ) said its move will be effective from March 29, the day Britain is set to exit the European Union. The company described it as insurance against the risk of a disorderly "no deal" Brexit.

Sony made the decision because "there is a lot of uncertainty around Brexit," spokesman Takashi Lida told CNN Business. It's "best to prepare in case no deal is reached" between London and Brussels, he added.
