Inexpensive Health Insurance Zenrosai

Hello all. I recently heard of a reasonably priced health insurance plan called Zenrosai from another expat here in Japan. If I recall correctly, they said they pay about ¥3000 per month for pretty extensive coverage, but I haven't been able to track down this specific plan. Has anyone else heard of this or actually use this insurance plan? Would love to hear your opinion if you do use it. Thanks in advance.
