Imperial Palace in Tokyo

If you have free time of 30 minutes in JR Tokyo station, you are able to enjoy magical and fantastic tour to explore the history of Japan.

Now, many joggers enjoy running for about 3 miles around Imperial Palace as their hobbies.

Do any of them get conscious of the truth that beyond the moat, shogun used to reign Japan for 280 years by absolute power、don't they?

I was a little scared to think that beyond the moat and thick forest, invisible grudge might be wriggling.

Am I coward or too sensitive?
