The very recent experience shows that a SAL parcel sent from Tokyo is arrived in Istanbul just in 5 days.

From a Tokyo local post office to the TOKYO INT’L POST OFFICE Outbound: 2 days – From Outbound to the İSTANBUL UKİM (INT’L PARCEL PROCESSING CENTER) Inbound: 3 days

So fast!

JAPAN POST has a very efficient mail system.
