Hi,
Yes Japan is a wonderful place for photography. Some of your images made me feel nasukashi.
I lived there for 15 years (I am now in Singapore) and I hope to get back this next year to visit friends and so some photography.
As for fine cameras, I just sold my Ebony 45 SV which, IMHO is the finest flatbed veiw camera you can buy. I got so spoiled there with my darkroom and access to chemicals, etc. When I moved to Singapore I realized my darkroom days were gone for sure. I have recently switch do digital thus the reason I sold my Ebony to help pay for my 1DS MK II. But I digress. . .
The only problem with photography in Japan is power lines! It is amazing how many wonderful views and scenes are marred by them.
Gambatte,
Spencer
