If you really want to get a larynx work out, go to とうきょう. It's loud, it's crowded, and you have to yell the entire time to get people to hear what you have to say. You also know 18 levels of kanji and you really want to shout them all out, which makes your voice box tired (but makes you happy).

Because of my laryngeal inflammation, it's painful for me to even breathe or drink water.
