I'm looking to buy a replacement Pan (B273) for my Zojirushi NP-GBC05 (3 Cup Model) rice cooker. On my last trip to Tokyo (4/4) I couldn't find a single store that sold replacement parts, only complete rice cookers (which by the way there are about a gazillion varieties of). I'm headed back on 5/24 and I was wondering if someone could please point me in the right direction on where I could possibly find one to buy? Thank you.
