Is January a Good Time to Visit Osaka?
January is a good time to visit Osaka if you are seeking unique cultural experiences among smaller crowds. Weather-wise, Osaka's clear winter days can be cold, but will provide an excellent backdrop for sightseeing, which should include the Osaka Castle Illuminations. If you are arriving at the start of the month, you can witness Hatsumode, the first shrine visit of the year.
While January has its advantages, the cold weather can be challenging, with temperatures dipping close to freezing on some days. This can make outdoor activities a bit uncomfortable for those unaccustomed to colder climates. Rainfall, though limited, might also occur sporadically, which can make sightseeing less pleasant, particularly if you're unprepared.
The post-New-Year closure of specific shops, restaurants, and attractions can also be inconvenient. Most businesses close for a few days during and after the New Year holiday, which can limit dining or shopping options in earliest January.
Top Places and Activities in Osaka in January
One of the highlights of this season is visiting Osaka Castle when crowds are few and you can fully appreciate the architecture, calm atmosphere, and winter illuminations. Another interesting thing to do in January under the clear skies is to celebrate prosperity and good fortune at Osaka's Toka Ebisu Festival, especially on a sunny winter day
1. Celebrate New Year, the Most Important Festival in Japan
In January, Osaka comes alive with celebrations of New Year, the most important festival in Japan. One of the key traditions is Hatsumode, the first shrine visits of the year. Recommended shrines to witness or participate in these vibrant gatherings include Sumiyoshi Taisha and Osaka Tenmangu. In these gatherings, offerings are made, fortunes are drawn, and people celebrate the beginning of the year with their loved ones.
These visits typically happen in the first days of January, and the shrines are often decorated with colorful banners and lanterns to create a festive atmosphere.
2. Marvel at the Magical Winter Lights at Osaka Castle
January evenings in Osaka are perfect for enjoying the winter light displays at Osaka Castle. These illuminations transform the castle grounds into an incredible spectacle, with sparkling lights and reflective views over the moats.
Since the castle area is less crowded in January, you can appreciate the lights and the historical surroundings in a more peaceful setting.

3. Celebrate Prosperity and Good Fortune at Osaka's Vibrant Toka Ebisu Festival
Another major event in Osaka in January is the Toka Ebisu Festival, celebrated at Imamiya Ebisu Shrine from January 9th to 11th. This lively festival honors Ebisu, the god of business and prosperity. It attracts about a million visitors each year, and the event is marked by lively parades and ceremonial blessings as locals seek good fortune for their businesses in the new year.
One of the key traditions is purchasing lucky bamboo branches decorated with charms. Many visitors join the festive atmosphere, witnessing traditional performances and participating in rituals like ringing bells to attract the god's attention.
4. Stroll Around the Bustling Districts of Dotonbori and Namba
Known for their neon-lit signs such as the Glico Running Man and endless food stalls, Dotonbori and Namba are a haven for food lovers eager to try some of Osaka's famous dishes like takoyaki (octopus balls), okonomiyaki (savory pancakes) and steaming bowls of ramen.

What to Wear in Osaka in January
In January, Osaka's cold-to-cool weather means layering is essential. Be prepared for it to be much warmer indoors and to need to remove layers.
For outdoor activities like sightseeing, we recommend wearing a warm coat, scarf, and gloves. These would help you stay comfortable in the chilly air in the mornings or evenings. A sweater or fleece is also useful for layering underneath.
Waterproof shoes are recommended for the occasional rainy day. Lighter layers underneath a warm outer jacket would be sufficient for visiting an onsen, exploring museums, or shopping along the streets. Don't forget to pack thermal socks or innerwear.
