What Day Was November 14, 2025?

I have summarized what kind of day yesterday, November 14th, was in Japan.

World Diabetes Day

This is an international day established by the UN General Assembly in 2006. The date was chosen to coincide with the birthday of Dr. Frederick Banting of Canada, who discovered insulin. The purpose is to raise awareness of the global threat of diabetes, which claims one life every six seconds worldwide. The symbol is the "Blue Circle," which features a blue circle motif, with "blue" representing the UN and the sky, and the "ring" representing unity. Around this day, blue light-ups, events, and symposiums are held all over the world.

Good Stone Day

Established in 1999 by the Yamanashi Stone Processing Industry Cooperative. The date comes from the wordplay "ii (11) ishi (14)" and the "Taishi-ko," the memorial day of Prince Shotoku, who is revered by stonemasons. It is a day to promote the culture and tradition of honoring ancestors with gravestones, as well as the skill of building beautiful gardens with stone masonry. Exhibitions of stone-related art and other events are held.

Good Resin Day

Established by the Chubu Japan Plastic Products Industry Association. The date comes from the wordplay "ii (11) jushi (14)." It is also known for the fact that on this day in 2002, 1,114 "Expo 2005 Aichi umbrellas" were donated to Aichi Prefecture to commemorate the association's 45th anniversary.

Seijin no Hi (Day of the Flourishing Person)

Established in 2001 by the Japan Veterans Club. It is derived from the wordplay "ii (11) toshi (14)" (good age). The concept is to enjoy life until the very end by utilizing one's four abilities: knowledge, skills, experience, and sensibility.

Women's Lib Day

On this day in 1970, Japan's first Women's Lib convention was held in Shibuya, Tokyo. Women's Lib refers to the women's liberation movement that began in the United States in the late 1960s and subsequently spread globally. It serves as a commemorative day for the historic movement aimed at improving women's rights.

Anti-Aging Day

Established in 2007 by the NPO Anti-Aging Network. The date comes from the wordplay "ii (11) toshi (14)" (good age). The purpose is to establish preventive medicine to prevent lifestyle-related diseases and to increase awareness of methods for maintaining a "youthful appearance." Anti-aging seminars, the announcement of the Anti-Aging Awards, and anti-aging senryu poetry contests are held.

Saitama Citizens' Day

Established by Saitama Prefecture in 1971. It originates from the fact that Saitama Prefecture was born on this day in 1871 due to the abolition of the han system and the establishment of prefectures, and it was established to commemorate the 100th anniversary of its birth. On this day, public schools in the prefecture are closed, and commemorative ceremonies for Citizens' Day, various competitions, and free or discounted admission to leisure facilities are offered. Saitama Prefecture has a population of approximately 7.32 million, ranking 5th in the country, and its prefectural capital is Saitama City.

Oita Citizens' Day

Established by the Oita Prefecture Council for the Promotion of the Prefectural Movement to Build Tomorrow. On this day in 1871, Oita Prefecture was born due to the abolition of the han system, and the name "Oita Prefecture" was used for the first time. However, since it is not an official commemorative day established by ordinance, it seems that there is little interest among the residents. Oita Prefecture has the highest number of hot spring sources and the highest volume of hot spring water in Japan, and uses the catchphrase "Oita, the Number One Hot Spring Prefecture in Japan."

Day to Thank Doctors

Established by D-Plus Co., Ltd. The date comes from wordplay where "11" represents the bond between patient and doctor, and "14" represents the doctor. The goal is to promote better medical care for both patients and doctors, and it suggests giving a handkerchief to one's primary care physician to express gratitude.

Good Investment Day

Established by Navigator Platform, Inc. in 2017. The date is based on a pun for 'ii (11) toshi (14)' (good investment) and expert theories suggesting it is an optimal day to start investing. The purpose is to deepen understanding of various investments, such as stocks and real estate, and to make it a day to consider better investment options for oneself.

Good Boss (Leader) Day

Established by the Japan Leaders Association in 2018. The date comes from a pun for 'ii (11) joushi (14)' (good boss). It is a day to remember to express gratitude as a good boss to stakeholders, including employees and their families, customers, shareholders, and business partners. The association conducts courses on 'boss studies' and 'organizational development'.

100-Year Life Era Day

Established by Asahi Soft Drinks Co., Ltd. in 2018. The date comes from a pun for 'ii (11) toshi (14)' (good age/year). It was established as a day to re-examine one's health as we enter the 100-year life era. The company provides various health beverages, including FOSHU (Food for Specified Health Uses) and foods with functional claims.

Tartar Sauce Day

Established by Kewpie Corporation in 2022. The date was chosen because it falls directly above November 21, 'Oyster Fry Day,' on a weekly calendar. Tartar sauce is a versatile sauce that goes well with various ingredients such as vegetables, fish, meat, and bread. It was first sold commercially in Japan in 1966 and has become popular along with the spread of Western-style cuisine.

Kanmon Bridge Day

Established by NEXCO West in 2023. It originates from the opening date of the Kanmon Bridge on November 14, 1973. The Kanmon Bridge is a suspension bridge with a total length of 1,068 meters connecting Shimonoseki City, Yamaguchi Prefecture, and Kitakyushu City, Fukuoka Prefecture, and was established to commemorate the 50th anniversary of its opening. It continues to contribute to regional development as a road connecting Honshu and Kyushu.

GAP and SDGs Agriculture Day

Established by the Japan GAP Foundation in 2024. It originates from the establishment date of the NPO Japan GAP Foundation on November 14, 2006. GAP refers to the management standards and initiatives that producers must follow in the process of producing agricultural and livestock products, and it contributes to the SDGs in many aspects. The purpose is to help promote sustainable agriculture.

Kenki Day

Established by Kaniya Co., Ltd. in 2024. Since the product 'Kenki' is derived from the 'Kenki' (prefectural flag) of Saitama Prefecture, November 14, which is Saitama Citizen's Day, was chosen as the anniversary. Kenki is a popular product consisting of cheese cream with a hint of salt and reduced sweetness, sandwiched between biscuits. The company aims for it to be loved as a famous confectionery of Saitama Prefecture.
