Please note that if you wish to write to a student at Yamasa, or send something to yourself - it is best to use the Institute's address, NOT your/their student accommodation address. Simply write the name of the student on the letter or package underneath the Institute address and our internal mail system will deliver it to the student. Also useful for registered mail and courier items - where they won't be able to deliver it unless someone signs for it. In many cases the courier services attempt to deliver parcels to a student accommodation during class hours, so its better to have it sent to the Institute where the Customer Services staff are always on hand to assist.
