If you already started a topic about allergies, then I will add my problem. I also have an allergy.

My allergy is fleas.

When I was half year ago in Ukraine, fleas bite me, and that started a full allergy on my body, the "vacation" was awful, it wasn't a vacation, 14 days of nightmare.

Now I don't want it to happen in Japan, so I wonder if I possibly can live in Japan for 3 weeks without touching 1 flea, and if possible to tell me where there no fleas.

I know that in forest or where many animals walking around might appear few fleas, however I from Israel, and here, there are no fleas, though street cats/dogs are walking around.

So can I go for a vacation to Japan?
Where should I go? (so I will have no contact with fleas) lol
And where should I NOT go? (to prevent contact with fleas).

Thanks in advance!
