See this little guy? This is the Nagasaki mascot. They call him a sloth, I believe. Though I'm not sure what animal he actually looks like! You can see this critter outside of all the main tourist attractions not just in Nagasaki City, but also in Nagasaki Prefecture.
One of the tourist attractions where you can find this buddy is in Nagasaki City. After getting off the JR Train at Nagasaki Station, you turn left and take the number 1 train to Dejima. When you get off at Dejima you'll see this buddy standing outside of a large wooden gate.
Dejima is the once-fan-shaped island that was off the harbour at Nagasaki. There you could find the Dutch traders and their concubines kept. When Christianity was still banned from the Japanese islands, this man-made island was the only place western traders (and eventually ALL outsiders) were forced to stay while they were doing business. Now, due to land reclamation, the fan shape has disappeared and Dejima looks like it could never have been out at sea, since there is no water to even be seen outside of the salt water canal streaking along one side of it.
I'm not sure about tourists, but if you have a resident foreigner ID card, you get in for free (or cheaper). Inside is a wealth of knowledge in a reconstructed Dejima-setting museum. Very fascinating, especially the introduced plants that came with Dutch traders. Did you know that there are cacti in Nagasaki? There are!
Here is the main gate where you enter Dejima, you can see it from the Tram:
You can see the train station where you get off, sorry I don't have a picture from the tram! These two lovely gentlemen are playing the part of real Dejima guards from the 1600's.
If you ever come to Nagasaki, please enjoy your stay!
