Volta Global, the family office run by former managers of hedge fund firm Everest Capital, has turned to activism in Japan. Miami-based Volta’s first target is a small construction company: it’s asking Asanuma Corp. to spend 10 billion yen ($92 million) on a special dividend or share buyback, and to hand over all its profit for the current financial year to shareholders, according to a March 19 letter to the Japanese company that Volta provided to Bloomberg. Volta also urged Osaka-based Asanuma to publish more information in English.
