Selecting footwear for Japan in January depends on your destination: for Tokyo, Osaka, and Kyoto, sturdy, waterproof walking shoes or sneakers are essential. The weather is cold but rarely snowy in these cities, so comfort for walking 20,000+ steps a day on pavement is the priority. However, if you are heading to "snow country" like Hokkaido, Nagano, or the Japan Alps, you must wear insulated, waterproof boots with excellent traction. Ice is a major hazard on city sidewalks in the north, so many locals use "slip-on spikes" or cleats that can be bought at convenience stores. A crucial tip for any January trip is to choose shoes that are easy to slip on and off, as you will frequently be removing them to enter temples, traditional restaurants, or fitting rooms. Avoid shoes with complicated laces or those that require a shoehorn, and pair your footwear with thick, moisture-wicking wool socks (like Merino) to keep your feet warm during long days of exploring the crisp, winter landscapes.
