Because it's an island....

Answer 2

The eastern coast of Japan is warm even in January because -

• The eastern Japan is actually an island, so the climate of this region is heavily impacted by the ocean currents of the nearby marine environment.
• The nearby marine environment of the eastern Japan is mainly dominated by the warm Pacific current.
• This warm Pacific current is the reason behind the warm weather situations of eastern Japan even in the month of January, when other countries are having their normal winter season.
