Mochi at the new year remains a hazardous substance

14 Comments

During the first three days of 2023, a total of 19 people in the greater Tokyo area received emergency treatment for mochi lodged in their throats, of whom four died. Once again confirming that mochi, a food made from glutinous rice, traditionally consumed at the new year and other celebratory occasions, can be a hazardous substance.

Broken down by age, 13 of the 19 receiving treatment were in their 80s, three in their 90s, and one each over age 100, in their 70s, and in their 30s, respectively. All four fatalities involved people in their 80s.

One 82-year old man was reportedly saved when a family member followed the instructions given over the telephone after they dialed the 119 emergency number.

As Nikkan Gendai (Dec 29) reports, two main factors can cause mochi to become lodged in the throat. One is that many seniors have missing teeth due to a variety of reasons, such as periodontal disease. What's more with advancing age their tongues become weaker and with it, the ability declines to transport chewed food to the throat. Moreover, elderly people's salivary glands tend to produce less saliva, leading to a decline in ability to swallow. If particles become lodged in the windpipe they can choke.

"Likewise, as people age their ability to dislodge food particles through reflex action weakens," said Dr Fujiki Ishihara, head of Kita-Shinagawa Fuji Clinic.

"The second factor is the nature of mochi itself," Dr Ishihara continues. "It is composed of alpha carbohydrates, but as the temperature cools it changes to beta carbohydrates, which have a different structure and are harder to digest. As the mochi's temperature cools inside the mouth the risk of its blocking the windpipe increases."

Problems can be avoided by breaking up mochi into smaller, more easily ingestible, pieces.

But Nikkan Gendai warns that consumption of mochi can also cause problems for people of any age. For one thing, not chewing it thoroughly before swallowing can result in its becoming impacted in the intestine.

"The problem occurs within one day of having consumed the mochi," Ishihara said. "It can not only block the intestine but also reduce the flow of digestive juices, leading to abdominal bloating, constipation and dehydration. In the worst cases it can cause serious dehydration or abnormal generation of electrolytes. The body can go into shock with loss of consciousness, and in extreme cases death can occur."

Neanwhile, another annoying impediment to new year's serenity has surfaced in the form of a report that many seasonal shimekazari decorations being sold in stores are not made in Japan.

A shimekazari is composed mostly of a shimenawa, a rope woven from hemp fiber or rice straw that is used for ritual purification in the Shinto religion. China has come to dominate the market for the new year's ornaments many people attach to their doors during the holiday period, this despite Shinto being a native Japanese religion.

In Yukan Fuji (Dec 29), Hidetoshi Tojo, representative director of the International Culture Promotional Association, grumbles that a majority of the shimekazari sold in supermarkets and convenience stores are woven from varieties of aquatic plants the Chinese call shuicao (literally water grass).

Tojo, 50, isn't just any Tojo, but the great-grandson of General Hideki Tojo, Japan's wartime prime minister from 1941 to 1944, who was found guilty of war crimes by the Tokyo Tribunal and executed by hanging in December 1948.

Tojo's allegations were confirmed by the unnamed president of a company that markets such decorations.

"Due to Japan's declining birth rate, these decorations have rapidly lost their regional flavor. And the craftsmen who make them are aging and dying out," he told Yukan Fuji.

As a result, he said, perhaps around 80% of the shimekazari now sold in Japan are imports from China.

Tojo, determined to adhere to the old traditions, has learned how to weave his own shimenawa from native Japanese straw.

"There's a difference between knowing the reasons behind a traditional custom or ritual and not knowing at all," Tojo asserted. "I even chose to study world history instead of Japanese history to avoid being confronted with my great-grandfather's name. But over the past 10 years, I've finally come to terms with his reputation. As a result, I now feel that to start making shimenawa on my own was a natural step."

Mochi still killing the elderly - 4 died in Tokyo alone - is quite unbelievable after all of the news, info and warnings about the dangers.

One can assume that in most of the 19 emergency cases, probably none of them prepared the mochi themselves or ate it alone in their homes.

What were the family / friends / assistants thinking of?

Mochi is so delicious that it is worth the risk. I like to wash it down with hot sake, chased by a cold beer.

How is this relevant to the story?

Shimenawa may be part of Japanese Shinto but profit is culturally the Chinese god. If Japanese don’t want to have imported shimenawa either make your own or there is a market opportunity for someone to exploit!

"Investing" 2000-3000 yen buying a chocking rescue device (a simple pump and mask over the face of the victim to suck the obstruction) can save lives since it requires very little training to be used effectively, specially in houses with small children or elderly people. The worst thing that could happen is that you waste this money in something you end up never using, which would be very fortunate.

I love grilled mochi then wrapped with nori…so tasty. It also goes well with a thick slice of meatloaf

Mochi with ice cream inside or mochi strawberries. Eat slowly. Leave the solid blocks to the old. Handmade mochi is the best.

Wow, so many people dying from mochi, it's worth reporting these numbers so we can prepare ourselves.

Do not eat mochi alone. Have some oil nearby to ease the flow.

No offense intended, but I have never understood the attraction of mochi. Sorry to hear about people choking on it.

I got some in my eye this year. We were very drunk.

Tokyo is a big city, and we’re making sweeping general statements about old people’s salivary glands. A huge number of really, really old people ate it it with no problem. We’re talking about 19 who didn’t. That’s much less than the daily number of young people who walk into walls while using their cell phones...

Glutinous rice is a well described cause of obstruction in the digestive track. It may not be the most common cause of it but it is very far from being "the last food" to cause this problem.
