Too many sumo wrestlers
 

Not sure if this rather long and detailed article can be translated into English, but a recent domestic Japanese flight to Amami Oshima (one flight a day) could not take off due to overweight wrestlers and balance issues. Just four of them weighed 450 kg between them. Another aircraft had to found at short notice.

Google Translate is rather good now and seems to work well for Japanese -> English

I couldn't get it to work for some reason translating the whole web page, but within Chrome the translate option worked fine. Right-click, Choose Translate.

OK. It was my blocker, unusual.

Jimjim, that's brilliant. Many thanks! Not perfect, but close enough, and it saves me having to do the work. :ok:

Wot, nearly half a tonne!

I think you will find that that's 440lbs. But this is an aviation website, and confusing metric and imperial units happens regularly in aviation, sometimes with "interesting" consequences.

The wiki page you reference actually states:
