Actually what is the issue when Yen Sinks? Really?
They little debt in US dollar.
Their inflation rate is very low..they welcome higher inflation.

Exporter will see windfall from cheap yen.
Large part of the economy domestic  and will not be affected by the USD/Yen rate

Unfortunately, Japan needs to import a lot of raw materials and energy. The prices have shot up. 

As a result, Japan has been having trade deficit for more than 1 year! Depriciation of Yen and ascalation of prices of raw materials and energy will make the trade deficit worse.
