Nope. ITZK releases three new chapters every month with some one month break here and there but that happens very rarely. It's just that Coolmic ENG and other Coolmic translations releases them in a very slow schedule. Coolmic JP, in other hand, is like 10-15 chapters ahead of the ENG version.
I have to know, does ITZK release like one chapter every 18 months, then go back into hibernation?
