I love cucumbers, so it sound alright to me.
All of us agreed that it is pretty good... crisp and very refreshing. Sweet with subtle cucumber overtones, more like the taste of a melon as you get toward the rind. Not bitter at all. Pretty much like Sprite or 7-Up. Nice color, too. A light bluish-green - picture watered down mouthwash, lol.
We don't normally drink sugared sodas (or much diet ones either), but if they did make a diet version (not typical in Japan), I'd buy a supply for the summer.
FWIW
Now back to my Calpis Diet...
