Survey of 600 Men and Women Aged 20-70: Over 60% Recognize 'Doyo Equals Eel,' While Half Don't Know the 'Original Way to Spend Doyo' ~ NG and OK Actions During the Doyo Period That You Should Know ~

The 'summer doyo' period, which begins on July 20th, is widely known as the day to eat eel on the 'doyo of the boar day.' However, traditionally, doyo is a period when one should take care of one's mind and body at the change of seasons and be careful with activities that involve moving the earth or making major decisions.

On the other hand, due to changes in lifestyle and values in recent years, while people know the term 'doyo,' fewer understand its meaning and how to spend the period.

In their 20s, 'don't know' accounted for about 40% (39.0%), while in their 70s, 'know the details' was the highest at 33.0%, showing that recognition of doyo is lower among the younger generation and deeper among the older generation.

However, this percentage decreased significantly among those in their 40s and older, suggesting that traditional views on doyo are more prevalent among older age groups.

In this survey, while the term 'doyo' is recognized by many, it was revealed that there is a lack of knowledge about what to avoid or do during the doyo period.

The 'summer doyo' period of 2026 is about to begin. Therefore, this time, we will explain what doyo is, what to avoid during doyo, recommended ways to spend the period, and how to deal with it when you cannot change your schedule.

Things to Know When the Summer Doyo Period Begins

From July 20th to August 6th is the 'summer doyo' period. Doyo has traditionally been considered a time when the power of the god who governs the earth is strong, and it is believed that activities involving moving the earth or making major decisions in life should be done carefully.

This year's summer doyo is 18 days long and coincides with the summer vacation season, making it unrealistic to avoid all schedules. Therefore, it is important to know what is said to be best avoided during the doyo period, as well as how to spend this period and how to deal with it when you have no choice but to make plans.

Things to Avoid During the Doyo Period

During the doyo period, it is said that in addition to activities involving moving the earth such as gardening, home gardening, renovation, and groundbreaking ceremonies, major life events such as moving, buying a new home, changing jobs, starting a job, getting married, and starting a business should be avoided.

This is because doyo is considered a period when the flow of luck is likely to be unstable, and it is said that making major decisions or starting something new can make things difficult to progress as desired.

However, if you cannot change your schedule, it is recommended to utilize the 'in-between days (mabi),' which are said to be less likely to be affected by doyo. The in-between days of the summer doyo in 2026 are July 21st, 28th, 29th, and August 2nd, totaling 4 days.

Additionally, from July 26th to August 12th, it coincides with the 'Lion's Gate' period. In the spiritual world, this is considered a special period when the energy connecting the universe and the earth is high, and it is believed to support positive actions and new challenges. In particular, July 28th is a particularly auspicious day as it is not only during the Lion's Gate period but also the day of the dragon and the great day.
