When I was in Merangin, Jambi Province of Indonesia, there are coffee fields wherever I go. Either it's along the road, near the river, on mountain feet, even on mountain slope. Have you ever smell Coffee's Flowers?
The height and heavy flow make it possible for the waterfall to create splashes even on radius of 50 metres. Moreover there are a lot of stones on the river below, so the watersplashes even create pretty haze. On the right amount of sunrays and the right angle, this condition will create beautiful rainbow on waterfall.
In past days, Otaru Canal plays an important rule in Hokkaido. The canal was completed in 1923. In 1986, one side of canal was restored and the other side was turned into land. The land were used as walking street and garden --it remains 'till today. Warehouses were transformed into museums, shops, and restaurants --it became tourist attractions today.
