I did almost 4 weeks with 2 teens in Asia and only did a carry on and pack for each of us. Who are you all that need so much clothing over 5 days in summer???! We did laundry 2x. Easy and done. Proper washers and dryers no need to buy detergent as it's preloaded in the washer. We stayed at 2/3 starred and 4 starred hotels throughout Japan and China.
