Hi all. I'm finally starting to invest in NISA, and for now I picked 2 indexes, a world and an emerging market. I picked two valued in Yen so that I don't pay dividends tax from their American counterpart (the same ETFs but traded in usd). Then I had a look at the yen/usd and the yen/euro charts, and I noticed a steady decline of the Yen. I did some research and it seems that the reason is Japan keeping inflation so low that investors go abroad to seek better yelds (sorry I don't know the correct wording in english).
So my idea is that I don't see Japan changing their policies in the close future, therefore I believe the Yen will keep weakening in the next years.
Would it be a good idea to buy American ETFs traded in USD, instead of indexes that replicate the same ETFs but traded in Yen?
Would it give me an edge if the Yen keeps weakening (If I have USD they'll be worth more yen), even considering the higher fees?
Could it be useful to buy half ETF in usd and half in Yen?
P.s.
in case it's needed to know: I'm going to invest periodically regardless of crashes, for 10-20 years.
I hope my questions make sense, I'm relatively new to investing and I'm researcging as much as I can.
thanks to everyone.
