This is a Mizu Konro (water grill) from Hasegama. I purchased it at a local event about 5-6 years ago, but I haven't been able to use it, so it's been stored away unused. I am now putting it up for sale. Includes instruction manual (with some stains). The size is approximately 27 cm in diameter. The instructions mention a ceramic base plate, but I can also include the accompanying cedar base plate (approximately 2 cm thick). Thank you very much!
