The Japan Foundation Sydney website is a rich source of information, resources, and competition and grant opportunities.
Japanese Tea. If you miss that taste of Ocha you can buy it online at a much cheaper rate than locally. This company is reputable, having been used by some of us.
Fresh wasabi from Shima Wasabi outside Devonport: Tasmanian wasabi roots, leaves, and stems are available for online purchase.
Japanese Food.
In addition to Kawasemi Japanese Teahouse in Moonah, you can also have a unique sushi experience in Geeveston [not kidding at all] at Masaaki-san's little Sushiya which is getting increasingly popular with connoisseurs. You go in to the car park just to the back of the Forest & Heritage Centre off Church St. It's good to let Masaaki-san know you are coming as he often sells out by 2.30pm!
