There is a place which makes olive in Japan, Syoudo-shima(in Japanese). I've received a olive paste yesterday, The taste is very Japanese style. The ingredients were green olive, ginger, and ao-nori(green laver). You can paste it on Yu-doufu(warmed Tofu). Kinugoshi-Dofu would be better, but I only had Momen-Dofu, but not bad at all. Kinugoshi is more soften than kinugoshi.
