Yamada Seiyu’s signature Nerigoma (black sesame paste), is rich, creamy, and deeply nutty with a smooth, velvety texture.

At Yamada Seiyu, the sesame paste is made using traditional stone mortars to grind the seeds without generating heat — preserving their full flavour and aroma. This labour-intensive method only yields only 1.2 kg (2.6 lb) per hour, but the result is a silky, intensely flavourful paste which the founder fondly referred to as ‘Goma Neri Neri’. The name reflects the heart of the craft: neri means “to grind” in Japanese, and Goma Neri Neri symbolises the patient, repetitive grinding process that produces an exceptionally fine texture.
