So, since Kleeners seemed to have no idea what to request, here's a Q&A for the winners.
What pokemon stuff can we request?
Anything. This could be a plush or a small figure of your favourite Pokemon. Just as long as you don't ask for things that exceed the given budget.
Also keep in mind that the Pokemon merch available changes with what game was recently released. It could mean your requested Pokemon is not available.[/spoiler]
What omamori can we get?
You can get one of any type. The most common ones are fortune, good luck, health and safe travels.[/spoiler]
What do you mean with local candy?
With local candy I don't mean funny kitkats or puccho, but rather traditional Japan sweets called wagashi. I might swap to more modern candy if it proves impossible to find, however.[/spoiler]
What could I request? Or where from?
What you choose could be anything I can get in Japan as long as it falls within the price limit. This also means that you can also request multiple items as long as they don't exceed the budget.
You could, for example, ask for Magic Kaito 1412's Character CD, or instead ask for chopsticks, a hand fan and a small daruma doll.

Do we request the Conan stuff from the site you linked?
The Conan thing included will be completely random and varies in price depending on what place you got. First place could, for example, get a mug while third place gets a button. Only time will tell.[/spoiler]
