At the bottom of this eMail are the details for carry-on items ... everything else should be packed in your checked luggage.
Special note about flying: the air will be thin (low pressure) and very dry. For best results, you will want to untie your shoes and really loosen them up so your feet can swell, it is normal and they won't swell up that much, but if you don't they will begin to hurt and go numb (they fall asleep and they will tingle). DO NOT wear your contact lenses, your eye's will dry out and it will be more than 16 hours before you would likely take them out to give your eyes a rest. This will cause significant eye irritation ... you won't go blind, but they will be more than tired after the trip.
When you travel to Japan, if you don't wear your contact lens, wear your glasses and then you can pack your lens fluid in your checked luggage. Plan to use shampoo to shave with, then you can pack your shaving cream in your checked luggage.
We will send you a 1 quart zip-lock baggie, it will have 5 small containers, and all will meet the requirement of 3.4 ounce or smaller; use them for shampoo, conditioner, face wash, toothpaste, hair gel, eye drops, and anything else you might need below (including contact lens fluid if you like). Place the zip lock baggie in one of the side pockets of your carry-on bag; it should keep it isolated from everything else in case it leaks.
Let us know if this does not answer your concerns,
3-1-1 for Carry-ons
3-1-1 for carry-ons = 3.4 ounce (100ml) bottle or less (by volume); 1 quart-sized, clear plastic, zip-top bag; 1 bag per passenger placed in screening bin. One-quart bag per person limits the total liquid volume each traveler can bring. 3.4 ounce (100ml) container size is a security measure.
Be prepared. Each time TSA searches a carry-on it slows down the line. Practicing 3-1-1 will ensure a faster and easier checkpoint experience.
3-1-1 is for short trips. If in doubt, put your liquids in checked luggage.
Declare larger liquids. Medications, baby formula and food, and breast milk are allowed in reasonable quantities exceeding 3.4 ounces and are not required to be in the zip-top bag. Declare these items for inspection at the checkpoint. Officers may need to open these items to conduct additional screening.
