Getting your ear cleaned in Japan

Hey everyone, short question. I live in tokyo for three monthes now and now my time came to get my ears cleaned so they dont get cloaked up. Problem is, i have very small ear canals, and because i had some bad expiriences while i still lived in germany. im a bit anxious when it comes to getting my ears cleaned because of that. So i ask does anybody have expirienc with getting theire ears cleaned in japan? And if they would have any recommandations what i should do
