A seasonal washing soap bar made from a plant-derived soap rich in palm kernel oil and palm oil acid, with added iyokan peel extract to align the skin. The blend of essential iyokan oil extracted at the Yamagami Citrus and Herb Garden with mandarin orange and geranium essential oils creates a sweet, invigorating, refreshing aroma. In addition to iyokan peel extract, it also contains amachazuru extract and, to assist washing, honeysuckle leaf extract. The rich foam has a refreshing finish that produces clean, smooth skin.
