Trade data from Japan gives an insight into how the falling yen has been affecting the economy.
So far, it is been a positive thing for exporters, because their goods are cheaper for people to buy.
But not all businesses are happy as the falling yen is driving up the cost of many imports, like power.
Dr Marie Owens Thomsen, chief economist with Crédit Agricole Private Banking, told the BBC's Rico Hizon that Japan's recent moves to stimulate its economy are still being perceived in a reasonably positive light around the region.
