Where Can I buy high quality Japanese or Chinese Green Tea?

I want to buy it for my mother for mothers day. She does not like any flavored kinds, just plain. It does not have to be in tea bags but it can. I am looking for a place locally in Columbus or for somewhere online. I want high quality (not cheap). Also, i am not sure if I can find a tea pot or pitcher that you steep the tea in and there is a strainer that catches the dregs as you pour it.

1. try Asian grocery stores or online at Adagio.com or Teaspring.com .
2. thats tough if you dont wanna make a trip to china or japan find an oriental market or some sort of chinese grocery store and they should have a collection of loose tea leaves they might have a tea pot as well.
3. I get mine at the local Asian market. They have a huge number of teas (although about 80% are in bags). Teavanna has great teas (some flavored) and you can buy a tin with as much as you're willing to buy. Other good tea store will have the same.
