Japan in December 2027: Complete Month Guide — Illuminations, Christmas, Year-End

December in Japan is three distinct trips in one month. 1-10 Dec is the final koyo week — Kyoto late-fall foliage lingers at Nanzen-ji, Osaka castle keeps its colors. 11-20 Dec is winter illumination season at full tilt — Nabana no Sato, Shiodome, Omotesando. 21-31 Dec is quiet pre-New Year — city streets empty, locals shopping for Osechi, atmospheric but shut.

Quick facts: Japan in December 2027
