Flight to Japan

I decided to blog about my visit to Japan (rather than dialogues between Penguins and Polar Bears) beginning on Tuesday. I fly out with KLM from Edinburgh via Amsterdam, arriving in Tokyo at 9am local time on Wednesday. I'm spending three weeks in the land of the rising sun before returning to Scotland to 'thaul the winter's sleety drizzle'.
First question: what to do on the plane? It's a fourteen and a half hour total travel time, which I've never dealt with before. First key is obviously to avoid deep vein thrombosis. Frequent brisk marches up and down the aisle should see to that, with perhaps a calisthenics session over Moscow.
Next moot point: reading materials. Do I read up on the local culture, and try to bone up my Japanese in prep for meeting Yuuka's family? Or do I engross myself in a lengthy classic novel - say Tom Jones or Tristram Shandy, or Anna Karenina or even Moby Dick - one of those notorious behemoths that I've never quite got round to reading and always meant to? Adavantage of the latter - should pass the time quicker, and make me an intimidating intellectual powerhouse in the eyes of my fellow passengers. On the minus side, I will touch down in Tokyo in the mindset of a dilettante eighteenth century English rake - either that or a Russian nobleman anxious to discover the meaning of life at the same time as marrying off his daughters. Which is preferable? OK, yes, theoretically I could go for the tedious option of combining the two, but I'm inclined to think with the classics it's all or nothing.
Of course I could just cut the reading altogether and take advantage of the on-flight film option I presume will be available. Not sure about this one. What will I do when the film finishes? I've always found that watching a film makes me acutely conscious of not being as comfortable as I could be. If I'm on a cinema seat I want to be on the sofa. If I'm on the sofa I want to be in bed... and so on. But if I'm on the plane seat I'm not going to be going anywhere fast, so that may be frustrating. Not to mention I don't get to choose the film, and there's a high possibility it'll be dire. And it'll be really annoying to be watchign the same film as joe bloggs in the next seat, only half an hour behind. In such circumstances, the dignity of the printed word seems more and more attractive.
