Unknown Japanese rice crackers

From October 2010. Thanks aunt T. Since I received one of each individual packs without the outer box, I have no idea of their real identity. Each pack contains 3 cracker. They're very thin, airy and has the corresponding "toppings" sprinkled on top. You can taste the egg in the batter. This is expensive stuff.

Soy and plum:
Can't taste the soy but the hint of plum is very refreshing.

Pumpkin seed and almond:
The pumpkin seed is dominant and can't taste much of almond.

Green tea and red bean:
This one's different. Their tastes are equally matched and balanced. You can taste them both.

Peanut and sesame:
Smells strongly peanut. But you can tell there's sesame when you eat it.

Overall, very, very nice. It has to be expensive, though.
