Nao's Sticky Riddles

(formerly known as "Nao's Ten Riddles — Vol.03")

Hello my friends! This is Nao Fénix from Japan.

日本人挑戦者の皆様へ →

This is the first (and maybe the final) online riddle game I made in English.
In this riddle game you are supposed to proceed solving the riddles I present you, aiming for the Finale page that will be shown after passing the last (the 10th) page.

In each page of riddle you put your answer in the text box and click [Go].
If the answer is correct you will be taken to the next page; otherwise the error message will be shown.
When you put your answer follow the rules indicated below, unless otherwise specified:

Use Latin alphabet letters in lower case and/or Arabic numerals (eg. enter "japan" instead of "Japan")
If you believe the answer should consist of more than one word, just combine the words without any space inserted and make up a single character string (eg. enter "twowords" instead of "two words").

Each page also contains the [Clue] button, which will give you a clue for the riddle.
There might be other clues which are hidden (or implicitly shown) somewhere in the page.
But, of course, make your best effort NOT to use these clues to pass...

Note that the riddles presented here are mainly targeted for Occidentals (although some are for Japanese).
For "outsiders" it must be difficult to find the answer, but I hope you will never give up.

If your security tool blocks "referer" information, this riddle may not work successfully.
