A clinic that does skin tests for allergies

Hi everyone,

I’m looking for a clinic that does skin testing for allergies, instead of the one where they draw blood. I have asthma and I’m very new to it. Last month, I had an episode that seemed to indicate that I developed a bad reaction to red pepper as what my doctor told me. I learned from the asthma subreddit that skin and blood tests can detect two different things. My blood tests came out negative so now I want to do skin testing. I’ve been googling and so far, google can’t give me very accurate clinics that might offer skin testing on allergies. Anyone knows a clinic that offers that in Tokyo?
I have been prescribed with an epipen just in case, but lately, even with just a tinge of red pepper on my food sends me to use my inhaler. I don’t like this and it’s scaring me.
I’ve always not been good with spicy food but I could tolerate it. When the spice was too much, it just usually sent me to the bathroom, not little anaphylactic shocks. This really scares me a lot.

Thanks for your support in advance.
