What is the Gokusai series?

Gokusai is G Project's flagship onahole line. Each product is engineered around a specific internal concept — such as granular texturing, a uterus gimmick at the end of the tunnel, or multi-zone stimulation. The series spans both soft and firm options across different intensity levels.

Are G Project onaholes good for beginners?

G Project offers products across all experience levels. Softer, simpler tunnel designs in the Gokusai line are suitable for beginners, while products with pronounced textures or tight gimmick zones are better suited for experienced users.
