There&#x27;s one word that I expected to be in the list but it isn&#x27;t, which is もったいない (mottai nai)<p>It describes the situation where something&#x2F;someone that is still of some use is left unused and wasted, such as leaving food on the table or wasting somebody&#x27;s talent.<p>I&#x27;m a Japanese who&#x27;s been living in the US for more than a decade, and I always thought this one word represents what&#x27;s missing in American culture the most.
