Dust storm shrouds Tokyo in haze

64 Comments

A huge dust storm hit Tokyo Sunday, blanketing the city with dust that darkened the skies and rapidly transformed what had been a clear and sunny day.

Visibility in the capital deteriorated quickly as dry dust particles whirled through the air.

Meteorologists said the phenomenon was caused by a sudden cold front, and was not linked with the suffocating pollution that hung over the Chinese capital Beijing last winter.

"A rapidly developing low pressure system in the north was moving down south. It was bringing a snow storm in the north, and strong winds in Tokyo and surrounding areas," said a meteorologist at the Japan Meteorological Agency.

"In the Kanto region (Tokyo and surrounding areas), the strong winds picked up dry dust particles from the ground, which lowered visibility," he said.

The phenomenon was expected to be temporary, and rain should strip the dust from the air, he said.

Japan and other regional countries have voiced concern about the impact of airborne pollution drifting from their influential neighbor.

The toxic haze that periodically blankets parts of China has been blamed on emissions from coal burning in power stations but also on fumes from vehicles on the traffic-clogged streets of the world's largest largest auto market.

Media reports have said that environment ministers from Japan, China and South Korea will meet in May will discuss ways to combat air pollution.

Im confused. I heard the "smog" in Tokyo today was sand. Now this article says it is PM2.5. So which is it? And are the environment ministry telling people in TOKYO not to go outside too?

And don't forget. PM2.5 chemically interacts with the surface of the yellow sand to produce NPAH, which is a carcinogen. So we are actually getting a double punch from China. You can't breath easier. Just don't breath.

It is a combination of both PM2.5 and sand/dust. While many other parts of Japan have issued health warnings and recommended people stay inside the pollution levels are under the Tokyo metro Gov's health risk standard and they have not issued a warning. It is terrible stuff and gets in your eyes and throat. Anybody with any common sense would know to stay inside. I guess that is why I see so many Japanese wandering around and kids playing in the park from my apartment window.

The view out of my window earlier looked something like the darkest depths of Mordor.

That just maybe hay(pollen) fever.

It's actually a triple punch, two from the mainland and one domestic. Just stay home and if you do need to go out put on a decent mask and glasses and don't forget to dust yourself before entering the home.

I'd been looking forward to a day in the park with my little girl, since the weather started warming up. By the time the Mrs had finished pottering about the house it was lunchtime and when I looked out of the window it was like The Day After.

I'm asthmatic and my eyes and nose have been streaming all day too. Is this the new norm? Because if it is, I'm packing my bags.

It's not from China, according to the Yomiuri. It's dust and grit from the Kanto plain. That means we can relax, because it's "peaceful" particulate matter.

It's getting harder and harder to avoid pollution from China these days. You're not even safe in outer space where Chinese space debris recently hit a Russian satellite, knocking it out. Of course not everyone is complaining. Business must be booming for manufacturers of respirators and air filters.

http://www.arb.ca.gov/research/health/healthup/may02.pdf From here you can see that it's not just a "carcinogen", it's a floating death machine. 10microgram increase causes 8% increase in lung cancer and 4% increase in death, which is equivalent to 1000mSv/year in terms of cancer!

People need to start treating this stuff correctly, since it is incredibly dangerous, and unlike larger particles can't be stopped by even the best masks they sell in stores.

The Environment Ministry has recommended the public not to venture outside unless necessary.

Thank you, Jeff. I was wondering how we could be so certain this was of foreign origin as I watched the dust billowing up from the gravel "park" across the way from my home.

I'm finding it really difficult to believe the gov't is looking out for the public. I've been tracking pm2.5 down here in Kyushu for the past month using various websites. Since last Thursday the data has been mysteriously absent with occasional retroactive updates the following day. Prior to Thursday the data was updated every 2 hours. Yesterday a story was posted saying that the yellow sand would be high this weekend but that pm2.5 would not be a problem. Today they contradict themselves and admit the pm2.5 is high and then blame the data problem on overloaded websites. I've developed asthma and bronchitis since living here and I'm blaming it on the air quality. The public needs to pay attention to this issue and demand that the gov't try to protect its citizens. The air quality is only predicted to get worse over the next 5 years. Kyushu University has a forecast system, Sprintars, that has been accurate and reliable. Last week they predicted that this weekend's pollution would be the highest of the year - and then the gov't shuts off the data.

I read JeffLee's link,

WHich is it? China poison? Or Kanto dust?

Either way, I have been spending the last couple days indoors grading with my air filter on. (It is now also the height of the spring hay fever. Watery itchy eyes, runny nose.)

Folks this happens EVERY year in March, the early spring winds are quite nasty, they pick up dust & sand from farmers fields & it gets airborne, today was just a particularly bad day, some of the roads where I live have large drifts of sand today.

Toss in the pollen from all the sugi & it makes it pretty bad for many people.

The vast majority of what hit Kanto today was MIJ, not MIC

this is definitely yellow sand from China. I mean, I could wipe it off the railing on my balcony. pretty obvious.

GW is right, this isn't the yellow sand and 2.5 PM that everyone is talking about. It's sand from the farms around Tokyo.

Yeah, I'd wish some of the posters here would actually read some other sources instead of relying solely on JT and heresay. Of course, I admit, I thought it was yellow sand from China too - so guess what? I did some research. Checked the internet to look at current maps of 2.5PM/yellow sand, and there was NOTHING over Kanto. And the TV reports even said it was nothing to do with yellow sand, but called it 煙霧 or 砂じん嵐.

Kimokekahuna Hawaii:

Sorry, you'll have to blame someone else this time.

The cat who owns me refused to go outside today. Bet that has something to do with this dust.

yes, well FNN is reporting it is yellow sand/polution from China, and displays a graphic showing the spread of the stuff over N. Korea (lucky them) to Japan. I guess they do not believe it is local stuff. I don't think so either. From my balcony in Shinjuku, it was definitely yellow, as is the thin coating of stuff on my balcony rail. Glad I didn't do the laundry today.

Nobody denies it's PM2.5, but that doesn't mean it's chinese sourced. Coal plants in the north and west of Tokyo would produce more than enough PM2.5 to cause smog, as would cars and other things too. The article had first stated "China [...] smog has been called PM2.5 in Japan", which is why the people above were quick to point out that it was ridiculous to state that. The new article reflects the correct information that states the smog did not come from china.

Folks this happens EVERY year in March

I've seen the yellow sand before, but never the whole landscape turning yellow like today. We were out in rural Gunma and saw the dust being blown off the fields. It looked almost like the ground was smoking. Dunno if any stuff was being blown over from China, but a lot of what we got today was definitely home-grown.

It was pretty crazy... I went into Don Quiote, in Kawasaki, and when I came out the sky was darkening in the direction I was heading. You could stand and watch the cloud coming in. All the while I was thinking... Is this that yellow dust from China?

Still no good unless you mean a particulate respirator mask like the 3m 1860, regular surgical masks used in hospitals and clinics offer absolutely no protection. Even with a respirator that exceeds N95, you are still letting 15% or so of the particulates in, and almost all under 0.3 micron (with modern coal plants, most of the pollution is this smallest type anyway)

@barry Exactly what I was thinking. If you have a look at the latest map of radiation published, the dirt whipped up by the winds are from the kanto region ESP Kashiwa and the surrounding areas. It is the top layer which contains the caesium So I hope there has been testing done for this particular threat. Around minami ku saitama city was especially bad and You had to remain indoors.

LOL. I hope you're being ironic. The current smog is reported all from Japan, and in summer I get regular photochemical smog warnings in my Tokyo neighbor, advising children to stay indoors.

Everyday I can look out at Osaka bay and see the factory produced pollution that leisurely wafts it's way east over the major conurbations of Osaka.japan produces a lot of pollution but China produces more with its inefficient factories. What other animal destroys the environment like we do?

Urqinchina...if there was research carried out by the government, would you honestly believe the results? I know I'd have a hard time suspending a healthy scepticism.

But if this is dust blown up from farms and construction sites...what are people in Kashiwa (to use your example) supposed to do?

This was downright weird. Was out and about and suddenly world changed - like a winter's day. Everyone O spoke to thought this was from China.

@jeff lee I think you will find it was a mixture of both Chinese and Japanese sands. From the top of Aeon car park in Iwatsuki you could see farm dirt swirling while at a higher elevation you see clouds of brownish nature coming in. I have lived in China for 5 years and also lived in Japan for 15, so When I write something that offends your nationalistic Tendencies don't call us ignorant, usually there are facts behind the article.

Not at all, came from the other side. What it does include are coal, car, cigarette, and farm particles, all of which are far worse in terms of lung cancer.

I was mobile, on my bicycle, when I saw the brown/yellow clouds...

The afternoon before 3/11, and I thought, "What the HELL is it, NOW?"

I passed a father and his two kids on what started as a nice day, walking their dog.

I made a quick U-turn, when it got dark, with a yellow tinge, in the sky.

Passing by the family again, the father said "Sugoi, ne"? It was starting to get like a sandstorm!

I smiled and gestured up: "From China, with love..."

I took a few pics, and got home as quickly as possible...

Later, I noticed my black, sandy tears, and yellow dust on my balcony, as souvenirs...

It was obvious from what I saw in Saitama, that there was a mix of CHinese sand and JApanese dirt being rolled around. Here is a quote from an expert

Sakamoto, a professor of electrical engineering at Kogakuin University in Tokyo and an expert on pollution analysis, found yellow sand in a dust sample taken Sunday from Nerima Ward that apparently got mixed up with other dust.
