I search and found that it's located near Yaesu central gate but not sure whether it is in Okashi land or not? Thank you.

It's not Tokyo Okashi land.
諸国 ご当地プラザ(Shokoku gotouchi plaza) is moved. Now it's near the ramen street.
Although I don't know they still sell many kitkats.

OKay, today I visited the shop 諸国 ご当地プラザ that is located the end of TokyoEki-IchiBanGai(means the 1st Avenue in Tokyo station).
But there is 1 flavor "Matcha"(green tea) KitKat only.
The shop staff answered my question
"During summer, because chocolate is probably melting, the maker stop to produce it.
So we can sell goods left unsold now.
New ones will arrive after September."
And in the shop, there is this notice up announcing in English also.
I see KitKat is very popular with foreigners.

If you are keen for kitkat there is a duty free/ souvenir place at Odaiba- Aqua City that has lots of flavours- nicely packaged and not overpriced.

Also calling into random Family Mart/ 7-11 type stores may yeild rewards.

There was a few different flavors located in the gift stores at Narita Airport last month (blueberry cheesecake being one of them). Family Mart had mango flavor (brought back quite a few haha).

I'm interested to know more the one in Odaiba.
How is it per box?
