There are many ways to send packages from Japan, but the same rule applies to all of them:
THE BIGGEST / HEAVIEST THE PACKAGE IS, THE MORE EXPENSIVE THE FEES ARE.


The safiest, the fastest but the more expensive:


Package reachs you within 4-5 days, is automaticly insured for a maximum value of 20 000 yen, and is checkable on internet. Be careful to get your package within one week, because some Post Offices may not inform you they tried to deliver you the package, it will be returned to me after 2 weeks and the shipping fees WILL NOT be refundable.
FEES

Slower, not insured but less expensive:
SAL
Package reachs you within 2 weeks, but is not checkable on the net and is not insured in case of lost or damages.
FEES, (Blue field)

The slowest, the less secured but the less expensive:
BY BOAT (Surface Mail)
NO insurance and a one month trip for your items.
FEES (Green Field)

You want cheaper? Ok, here it is:
SAL Small Packet for packages less than 2 kilos!
FEES


* EMS INSURANCE ONLY COVERS DECLARED VALUE !!
* Customs taxes are NOT of my responsabiliy. Usually, not too big and not too heavy packages are not taxed, but I do not work at the Customs and cannot tell you if your package will be taxed or not!
* Shipping methods other than EMS are AT YOUR OWNK RISK !!


Make up your mind!
