That is not correct. As the yen declines, goods sold in dollars or other foreign currencies bring back MORE yen to Fujifilm. A declining yen is good for Fujifilm since most of their sales are overseas. Their recent year end financial statement alluded to this as their imaging solutions group gained over 2% in income just due to currency moves.
If all film raw materials were imported, then it would be bad for Fujifilm. It is very unlikely that this is true.
I'm thinking primarily of silver, which is likely to be the largest cost driver (at least for traditional b/w film). Since commodities are generally priced in US dollars or in Euros, it will take more yen to purchase a given quantity. I'm sure not all materials are imported
