Meiji/Taisho Period Shark Skin tea sets (similar styles made in AIZU- HONGO, Fukushima, Shigaraki)

These prolific shark skin with raised enamel tea sets have been labeled as Banko ware, Aizu Hongo ware (see link below) and Shigaraki ware. I recently came upon a Japanese Pottery book with very similar ware from Shigaraki from the Meiji period labeled as Ichin Kake or inchin Yaki. See photo below. 

*Thanks to Tanii Hozan for doing some research for me on the Shigaraki shark skin ware.
