Hakone yunessun launches food loss citrus bath this November

The Hakone Kowakien Yunessun, Hakone’s largest day-use hot spring facility, is set to launch its unique Mikan no Yu (Citrus Bath) on Nov. 1, in collaboration with JA Kanagawa Seisho.

The citrus bath, a winter staple in Japan, features locally sourced citrus from JA Kanagawa Seisho, utilizing fruits that are labeled as “processing use” due to minor blemishes, splits, or color inconsistencies that typically hinder their commercial distribution. The initiative aims to reduce food waste and effectively utilize produce that may not enter the market, while promoting local specialty products.

The Mikan no Yu is part of Japan’s long-standing tradition of “seasonal baths,” where medicinal herbs or seasonal plants are added to bath water. Bathing in citrus-infused water is believed to warm the body and prevent colds, thanks to the essential oil component “limonene” found in citrus peels, which is known to improve blood circulation.

As autumn brings vibrant colors to the mountains of Hakone and temperatures drop, Yunessun invites guests to immerse themselves in the sweet and refreshing scent of citrus while experiencing the local blessings and warming up from the core.
