According to a report in February by Business Korea, Samsung has even considered pulling out of Japan entirely, with the South Korean company reportedly making a loss on its presence in the country. There's a precedent for this: The English-language news site notes that in 2007, Samsung decided to pull its TV business out of Japan due to dire sales.
