After stumbling across the Christmas Market at Hakata Station, I discovered that Kyushu was actually holding many Christmas Markets across different JR Station locations. Kagoshima-chuo station happened to be another of those market locations, and despite being a lot smaller in size than the Hakata one, this market still had beautiful lights and some lovely stalls.
