The last time I went, I destroyed my sleep schedule a week out to get it as close to Japan time as possible. By the time I left, I was going to bed immediately after coming home from work. This probably isn't an option for sane people though. Also, stay hydrated. That should help regardless of how sane you are and try to get as much sunlight as possible when you arrive. [....]
Ha... tried to do that the first time I went to Japan.
My flight started around 1pm with an approximate arrival time between 7 and 8 am (which would be midnight at my point of origin). The week before the flight I completely revamped my sleep schedule so I'd fall asleep at 1 pm. And then when I finally sat in the plane I was dead tired... but couldn't sleep for even a minute. Arrived in Narita at 7 am, hadn't slept in over 24h by that time, had to go to Shinjuku to pick up my keys for my Sharehouse room (which was quite a long train ride from Shinjuku). Additionally it was end of June and the first "real" day of summer with temperatures up to 33 degrees... couldn't eat anything because I felt like I was dying and then I had to stay awake for the whole day still since I had to get back into a normal rhythm for work 2 days later.
It was literally the worst day of my life.
The next time I flew to Tokyo I made sure to book a flight that would arrive around midnight so I could just go from the airport to my bed. It was a WAAAAY more pleasant experience. So that's what I did from there on out. I'd even pay extra for a flight that arrives slightly later.
tl:dr arriving in the morning is beyond miserable.
Nah, I've flown plenty. Just haven't had such a massive shift in my sleep schedule like this in over ten years. I live in Oregon, and the time shift literally is at a place that when I wake up in the morning, I would be going to bed in Japan. That 8 hour shift may be a problem. [...]
Flying to Japan from the US is a waaaaaaaaaaaay more enjoyable experience than going from europe since you're moving with the earth rotation. To your inner clock it feels like you lost a couple of hours, but is nowhere near as straining as loosing half a day.
Well, I fly out to Japan on Thursday! Will be there for three weeks.
Itinerary is roughly:
Tokyo - 7 days
Kyoto - 5 days
Ryokan close to Kyoto - 1 day
Kobe - 1 day
Osaka - 3 days
Hiroshima - 2 days
Fukuoka - 1 day
Nara - 2 days
[...]
you got a rail-pass I assume?
some parts of your schedule feel like slight overkill imho. Like you could only spend only 1 day in Nara (which is enough to see everything at a legerly pace. You could use that day to go to Himeiji instead. Also 4 days for Osaka and Kobe feels much. If you're already going down to Fukuoka, why not just go further and go to Nagasaki? I thought it was well worth the extra time (also their atomic bomb museum is vastly superior). Kyoto has a lot to see, but I'm not sure if there's enough to fill 5 days. (I've seen pretty much all the key attractions + a visit to the dentist in 3 days). Another idea would be to go to Beppu while you're in Kyushu to get in some Onsen time. There are quite a few nice ones. Do the 7 days in Tokyo include a trip to Nikko and Kamakura?
having a rough schedule is good for orientation, but don't force yourself to follow it through. If you get the feeling that you've seen everything, don't feel bad for just moving on to the next destination/area! On the other hand, also don't rush yourself to see as much as possible. A good balance is key!
