Respect-for-the-Aged Day (Keiro no Hi)

What Is Respect-for-the-Aged Day?

Respect-for-the-Aged Day falls on the third Monday of September each year — September 21st in 2026 — though it was originally established on September 15th. The holiday traces its origins to "Toshiyori no Hi" (Day for the Elderly), which began in 1947 in the village of Nomadani, Hyogo Prefecture, and became a national holiday in 1966. It's a day to honor elderly people who have long contributed to society, celebrate longevity, and create an opportunity for younger generations to learn from their experience and wisdom.

The Origins: Honoring Elders Since September 15th

The roots of this holiday reflect a community coming together to support its elders and value their wisdom.

• Nomadani Village's "Toshiyori no Hi": In the chaotic years after the war, the village mayor proposed that the community draw on the wisdom of its elders to help rebuild. September 15th, a time when the agricultural off-season met pleasant weather, was chosen for practical, community-based reasons.
• The legend of Prince Shotoku's Hiden-in: According to one tradition, September 15th was also the date Prince Shotoku founded the Hiden-in, a facility at Shitennoji Temple that cared for the poor, orphans, and the elderly — adding further historical and cultural weight to the date.

How Experience and Knowledge Complement Cognitive Flexibility

Growing older isn't simply decline — it's also a process by which the brain maximizes what's known as "crystallized intelligence."

• The peak of crystallized intelligence: Vocabulary, insight, and the ability to draw on past experience to find optimal solutions — collectively known as "crystallized intelligence" — have been shown to peak in a person's 60s and 70s. The big-picture judgment that comes with age complements the more fluid intelligence typical of younger people.
• The positivity effect and emotional stability: Older adults' brains tend to respond more readily to positive information than negative information, a phenomenon known as the "positivity effect." This emotional stability can ease stress and increase a sense of psychological safety throughout a community.

Things Worth Knowing About Respect-for-the-Aged Day

• The Happy Monday system and the shifting date: Since 2003, the holiday has been observed on the third Monday of September. In response to requests to preserve the original date, September 15th is now designated as "Senior Citizens' Day," with the following week observed as "Senior Citizens' Week."
• The "digital senior" of 2026: Today's older adults are increasingly comfortable using social media and apps, staying active through lifelong learning and online communities. Technology continues to evolve as a tool to prevent isolation and support ongoing social participation.
• Longevity and lifestyle: Japan's status as one of the world's longest-living nations is attributed to a combination of factors — a balanced diet (washoku), moderate physical activity, and the psychological concept of "ikigai" (a sense of purpose).
• The benefits of reminiscence: "Reminiscence therapy," in which people share memories of the past and receive empathy in return, is widely used not only to help maintain cognitive function but also to affirm one's life story and boost self-esteem.
• Intergenerational interaction and brain health: Research suggests that older adults who interact regularly with younger people show increased activity in brain regions related to executive function and memory. Exposure to different perspectives can enhance neural plasticity for both generations.

Ways to Spend Respect-for-the-Aged Day

• Take time to listen to the stories of older family members or community members — their experiences of hardship and success offer valuable perspective for navigating your own challenges.
• Put your gratitude into words — through a letter, a phone call, or a small gift with a heartfelt message. Expressing positive emotion has been shown to release oxytocin, the "bonding hormone," in both the giver and receiver, boosting feelings of happiness for both.
• Look for role models who continue to challenge themselves regardless of age. Seeing people who refuse to let age define their limits can help turn anxiety about aging into something more like positive anticipation.
• Enjoy activities that promote healthy longevity together — a walk, a meal, or a brain-training game. Spending quality time together strengthens resilience within families and communities.

Let the Wisdom of a Life Well-Lived Light Your Path Forward

September 15th is a day to honor those who have lived rich and full lives, and to think about how their wisdom can be passed on to the next generation. The calm that comes with age, and the strength forged by overcoming life's many challenges, can serve as a guiding light for the path ahead. A few months into the new fiscal year, has the daily rush caused you to lose sight of important lessons and gratitude? Today, take time to listen to those who have walked the longest roads, and let their warmth and wisdom inspire you. What you gain from it may open your heart a little wider, helping you move through the new season with renewed warmth. Let's welcome a wonderful autumn together, with gratitude in our hearts.
