Japan deputy finance minister Motohisa Ikeda said on Thursday that a weak yen is generally beneficial to Japan as it has a high concentration of companies that export goods.

Ikeda, speaking to reporters, also said he would not comment on specific currency levels.

He added that he wasn't overly optimistic about the outlook for business sentiment after the Bank of Japan's tankan survey showed on Thursday that Japanese business confidence was at its best in two years in the three months to June and that big firms revised up capital spending plans.
