<h2><span style="color: black;">A commemorative day established on this date because of the pun with the "Ichijiku" of "Ichijiku Farmaceutical Co. Ltd."!</span></h2>
<tn>The pun:
<i>Ichijiku</i> ≈ <i>ichijuuku</i> → <i>ichi</i>(1) <i>juuku</i>(19)</tn>
<div style="text-align: center; white-space: nowrap;"><h1><span style="color: black;">The 19th of January is
Ichijiku Enema day!</span></h1></div>
<tn><i>Ichijiku</i> means <i>fig</i> in Japanese, and although the origin of the term is not 100% clear, it seems they may be called like that because their shape does resemble a fig. This enema is also the namesake of the company that makes them (see below), so it may be best left untranslated.</tn>
