TOKYO (Reuters) - A Japanese government spokesman said on Friday that sudden moves in currencies and other financial markets related to Britain's referendum on membership in the European Union are undesirable.

Deputy Chief Cabinet Secretary Hiroshige Seko told reporters Japan's government is worried about market moves and prefers markets to move stably. Seko also said the government will continue to closely monitor market moves.
