Rain happens everywhere. What's the difference between rain here or rain there. Is it the signs around the rain? The people are the same everywhere I think. Maybe it's the density of the signs, the colors, and what's under it all. Yet, the 99 cents store isn't that cool in the rain, but it has to be the signs. Then again, is it the signs, or is it the font or the characters? If it says, Bob's Big Boy, would this look cool? It wouldn't. As simple as it may seem, it's nice to see the rain in Tokyo, and although people are scurrying away out of the water, I'm trying to get in it. My Ricoh may not agree.
