Nosebleeds (鼻血) in Kansai

This is not a full-blown scientific study with massive a research base, just a small informal survey of children I have regular contact with in Kyoto and Osaka. I asked the question to 16 children "Recently, do you sometime get nosebleeds?". For privacy reasons, no names are given.

1. Girl M (14 years) NO

2. Girl S (10 years) YES

3. Girl A (10 years) YES

4. Girl H (10 years) YES

5. Girl H (10 years) NO

6. Girl T (13 years) NO

7. Girl M (13 years) YES

8. Boy N (8 years) YES

9. Boy J (12 years) YES

10. Girl S (4 years) NO

11. Girl S (10 years) YES

12. Girl K (12 years) YES

13. Boy K (8 years) YES

14. Boy M (10 years) YES

15. Girl Y (10 years) NO
16. Girl M (4 years) YES

Eleven out of sixteen reported that recently they have suffered nosebleeds. When asked about food, all said they ate sushi regularly. Only two didn't eat mushrooms, however, one of the common base ingredients in Japanese cooking is shiitake mushroom. All ate school lunches that includes milk daily. It was reported that Kyoto school lunch milk includes milk from Iwate.[1][2]
Another factor that can't be ignored is the burning of radionuclide contaminated debris from Tohoku in Osaka Bay[3]. The highly radioactive waste is then used as landfill in an island in Osaka Bay. This island is usually surrounded by local fishing boats.

As this is not an official study, it has to be taken with a grain of salt. But, this is not made up. Only the future will tell, as the Japanese government has a campaign to encourage citizens to eat Fukushima food to stop baseless rumours. Official medical research is discouraged.
