The campaign will run from sometime in April, and will be run for two years (or longer, depending on how long I end up staying in Japan this time), probably somewhere in the Nagoya area (ideally I'll get my own place that we can play at, and if not we can probably solve that problem somehow). One session every month to couple of weeks, since a friend of mine is coming from Yokohama to play and it depends a little on his workload. Other than that any day or the week will probably be fine, although ideally longer than average sessions are what I'm aiming for (basically whole-day sessions, or something like starting right after lunch and playing into the night), so weekends are perhaps the easiest for most people involved.
Perhaps the easiest, schedule-wise, will be to plan fairly far ahead, setting aside a weekend here and there? Hence why I'm posting here even though I'm still not in Japan yet.

I think that we can try to be flexible and play when everyone can, using 1-2 long-ish sessions a month as a benchmark.
Some (very brief) information (really just a short piece of fluff along with the organisational details I've just written here):

The mood of the game is in line with the dark 40k setting as I interpret it and enjoy it with all its nuances, fairly deep with extensive lore, dark secrets and heroism and villainy. The PCs should be human and (some kind of) 'good guys', although nothing is never black/white, especially when Rogue Traders are involved. The action will hopefully be larger-than-life and more heavy on tension and drama than rolling buckets of dice, since that suits my taste in GMing.
If it fits your tastes and if you feel that you can fit it into your schedule you're more than welcome! In that case you can PM/email me to discuss character creation.
