I agree with the advice to stay awake after arriving from the States. (If you're flying out of DFW, that's Central Time, the same as Minneapolis.) If arriving at 5:00PM, that means 2:00AM CST, so it will be hard to keep the kids (and yourself!) awake, but do your best. Fortunately, international flights these days have plenty of movies and games for all ages loaded into the in-flight entertainment systems, and if your children are old enough to read, you may want to load some books onto an iPad or other tablet.

Ideally, one should sleep no more than two hours on the flight over. Before pulling the shades down became nearly compulsory, I used to sit by a window and keep the shade up, creating the impression of an unusually long afternoon. I found it easier to adjust to the time difference that way, but I guess I'm outnumbered now.

I adjust easily to the time change when going TO Japan. I simply stay up till 10PM Japan Time, which is the equivalent of pulling an all-nighter, and then sleep for 8 hours, which puts me at 6:00AM Japan Time.

However, in 35 years of trans-Pacific travel, I have not found any way to prevent two or three days of brain fog after the trip back.
