Today is the 11月11日 (11th November), or, as Ezaki Glico would prefer, ポッキー&プリッツの日 (Pocky and Pretz Day). However, the confectioner is not the only one to claim the day. The Japan Anniversary Association has 49 entries for today.
Umaibo, crayons, bread rolls and fresh ginger are among the other similarly-shaped products promoting themselves today. https://www.kinenbi.gr.jp/
Bass, tachinomi (drinking standing up), Steamed pork buns, and Nagano mushrooms all want to get in on the act.
Those are just the days which registered with the Japan Anniversary Association. It costs 150,000 yen to certify a day with them (they do a discount for more than one day), and not everyone bothers to do so.
