What's the lettuce umbrella? Picture talks everything. Just go to the web site:

Yes. This is an umbrella looks like lettuce. This should be a quite good souvenir of Japan.

That is too cool, where can I get one and how much?

I would like to give them out as gifts.

Does it indicate if I can order them online and the cost anywhere?

After you click the bottom pink circle which is Contact page, you need to  fill out the form. Then they will send you e-mail by Japanese, I think.

That is adorable. I want one for me!
