If you're in Tokyo and on the west side AND have an interest in ULF.... check out the small exhibition by landscape photographer Amano Takashi at Ikebukuro station. He shot 8x20 Provia 100F that was custom-ordered from Fuji, then enlarged to a length of about six feet. (You can see more of his work at amanotakashi.jp. Japanese text only.) It's not worth a trip across town, as there are only about a dozen images, but it was my first exposure to such a large format, and I was really impressed.
