Staying up late on New Year’s Eve is allowed to welcome the Toshigami (New Year deity).
As a New Year’s Eve memory, many people probably remember being allowed to stay up later than usual.
A leading explanation is that it was to welcome the Toshigami (the New Year deity), and going to bed early on this day alone was thought to be disrespectful to the deity.
Today, midnight marks the change of date and is quite late, but in the past, sunset was considered the boundary between days, so even “staying up late” might have meant going to bed earlier than we do now.
Even if you usually just stay up without thinking much about it, knowing this reason might help you welcome the New Year with an even happier feeling.
In the Edo period, snowmen were shaped like Daruma figures.
During the mid-Edo period, the roly-poly toy, which came from China, became popular.
This roly-poly evolved into the limbless Daruma shape and spread as a children’s toy.
It’s believed that children imitated the familiar Daruma to make snowmen.
Unlike modern snowmen assembled from multiple parts, Edo-period snowmen were represented as a single round mass, and it’s said that offerings such as fish and green onions were sometimes placed before them.
In the Edo period, snowmen were often appreciated for viewing and treated as good-luck charms.
The taste of oden differs between the Kanto and Kansai regions.
Oden, a classic winter dish, is beloved nationwide in Japan, but it’s often said that Kanto and Kansai have their differences.
While both share a dashi base made from bonito and kelp, Kanto typically uses broth seasoned with mirin and sake plus dark soy sauce, whereas Kansai uses broth seasoned with salt and light soy sauce—this is the biggest distinction.
The simmering method is also said to differ, and Kansai’s version is generally considered lighter in flavor compared to Kanto’s.
The ingredients used can vary as well, so it’s also recommended to look beyond just Kanto and Kansai and find the style of oden that suits you best.
In the old lunar calendar, December is called “Shiwasu.”
The alternative names for each month, also called the traditional Japanese month names (wafū getsumei), have ancient origins and are mentioned in Japan’s oldest chronicle, the Nihon Shoki.
When December is expressed using these traditional names, it is called Shiwasu; even the characters themselves convey the sense of bustle as the new year approaches.
While Shiwasu is the standard, there are also names like Gokugetsu and Harumachizuki, all of which evoke the severe cold of winter and the period of moving toward the New Year.
It’s also worth noting that these names were used in the old lunar calendar; let’s consider what time of year they correspond to in the present day.
It is said that the custom of everyone sharing a hot pot began with a dish called “shippoku.”
When it comes to classic winter dishes, hot pot is a staple—not only for its variety of flavors, but also for the fun of everyone gathering around the table.
It’s said that this style of sharing a single pot originates from shippoku cuisine, a traditional Nagasaki fare introduced from China.
In shippoku, dishes are laid out on a large round table for everyone to share, and from there the practice of taking food from a single platter or pot spread.
It’s also recommended to learn about the history—how hot pot evolved from individual small pots to today’s communal style.
