is there caffeine in this?

Please see http://www.itoen.com/ready-to-drink/oi-ocha/oi-ocha-dark-16-9-fl-oz-12-bottles-case, which is worded confusingly, saying that it has 50 mg per 8 oz even though each bottle is 16.9 oz, so it's actually a bit north of 100 mg. If you want less caffeine, the non-bold version only has 60 mg per bottle.

Does the cold green tea have the same health benefits as hot green tea?

I think what you want to ask is: does bottled tea have the same health benefits as freshly brewed tea? I heard that it doesn't. I think you lose some healthy components like within an hour after it is brewed. I don't think Bottling preserves everything good in fresh tea. I bet this has been researched. Wonder what good things are left in bottled teas, and if there's any Bad components created. Pretty sure plastic bottles will add some bad components.

Is this product made in Japan or China? I've seen product listing that state one or the other ... Thank you!

This clearly states on the box they come in and the bottles that it's a product of Taiwan. It is misleading because their Amazon account says made in Japan etc... The leaves might be from Japan but it's not a product of Japan. I was dissapointed when I saw this but I still like the tea.
