Mastodon is big in Japan, and the reason why is uncomfortable
&quot;Uncomfortable&quot; as in &quot;offends my American puritan-inspired sensibilities&quot;.<p>&quot;Pardon him, Theodotus: he is a barbarian, and thinks that the customs of his tribe and island are the laws of nature&quot;. George Bernard Shaw, &quot;Ceasar and Cleopatra&quot;.<p>(Slightly off topic: Feynman had a nice story in one of his books about how the main in a Japanese guesthouse he stayed walked in while he was naked and having a bath. She didn&#x27;t flinch and just went on about her business like nothing had happened, and he was thinking what a fuss&#x2F;embarrassment etc that would have caused if it happened in a hotel in the US -- when it&#x27;s just an adult being naked with another adult present. It&#x27;s not like everybody hasn&#x27;t seen genitals before or it&#x27;s a big deal.)
