Which route are you hiking in May? For most areas here the rainy season doesn't start until june - unless you are right down in southern Kyushu or Okinawa. So in which case you might not have to worry too much about humidity at that time.
Looking at (more challenging parts of) the Kumano Kodo, south-west of Osaka, which is shaping up to be a fun trip! We were looking at further north, but my friend and me are flying from different parts of the world and want to maximise the time in the back country.
You are correct - it's a changeable time and we may be into summer without any sign of bad weather. Last time I visited was October, and we caught the tail end of a typhoon.
Edit: Just saw your location

I agree with a lot of the responses from everyone else, and will just chime in on certain items:
2. I typically shoot in warmer weather and exclusively in raw (and rarely with LV), and find I get slightly less than 400+ shots. I do find the genuine Pentax batteries to provide more shots than the after-market brand I bought.
3. The 18-135mm spends the most time on my K-70, and by a wide margin, compared to my other lenses. (Second would be the 55-300mm PLM.) Considering all factors and to maximize flexibility, I use the lens extensively when traveling. I find it's just a good, all-around "balanced" lens.
6. I have had my K-70 for just about two years, and am at around 6k shots...all good so far! (Knock on wood.)
Good luck!
Many thanks. Yeah, the 18-135 is a very known and solid commodity. I also thought about taking another copy of the 16-45, another lens I know well and which is lighter (and IMO gives better results), but not weather-sealed and with a much larger filter on the front.
