Reference excerpt

Heiwadai Park (平和台公園) or Miyazaki Peace Park is a municipal park in Miyazaki, Miyazaki on Japan's Kyushu Island. A popular honeymoon destination for Japanese couples, the park's Peace Tower has generated controversy because of its place in Japanese history.

Park description Heiwadai Park is located in the Shimokitagata-cho region of Miyazaki City. It has an area of 68.8 hectares (0.266 sq mi). The park houses the Miyazaki Shrine, which is devoted to Emperor Jimmu who by legend is from the Miyazaki region.

History The park was constructed in 1939 to commemorate the 2,600th anniversary of Japan's Imperial establishment. The Hakko Ichiu tower, later renamed the Peace Tower, was built in 1940. When princess Takako Shimazu honeymooned there in 1960, the park became a favorite destination for Japanese newlyweds. Hibiya Park was designated Heiwadai's sister park in 1965, in a ceremony in which Heiwadai received doves from Hibiya.

Haniwa Garden

The Haniwa Garden, 9,000 square metres (2.2 acres) in size, is located north of the Peace Tower. A central feature of the Haniwa Garden is more than 400 haniwa (terracotta clay figures) which are placed along paths within the garden. These are earthenware replicas of burial haniwa originally excavated at the site. These figures take the form of animals, boats, dancers, houses, and warriors.

Peace Tower

A 36-metre (118 ft) tower was constructed in 1940 to memorialize the installment of Japan's first emperor, Jimmu. The original name was Hakkō ichiu Tower, meaning "Eight World Regions Under One Roof," a slogan of the Imperial Japanese Army. Designed by Jitsuzo Hinago, the tower was created from stones gathered from around the then-current extent of the Japanese empire at the cost of 670,000 yen. The writing "Hakkō ichiu" was removed after the Japanese defeat at the insistence of the U.S. military. The tower was the inception point for the torch relay of the 1964 Summer Olympics. Subsequent to the Olympics, which coincided with worldwide interest in the Japanese Imperial family, the local tourism association successfully petitioned the Miyazaki Prefecture to re-install the "Hakkō ichiu" characters. The tower has been a point of some controversy, as many Japanese citizens wonder how a structure created specifically to convey Japanese might during a period of conquest can now be a symbol for peace. Some people consider the lack of documentation regarding the militaristic genesis of the tower to subtract from the structure's re-imagined power as a symbol of peace. Other survivors of the period have stated that the tower allows the horrors of war to be passed down through generations. The tower has also been a source of controversy in China, as Chinese state media and some Japanese researchers have said the tower incorporates more than 370 stones pillaged from places that Japan invaded or occupied during World War II, including the Korean Peninsula, mainland China and Taiwan. On 13 December 2025, Yuyuan Tantian, a Chinese social media account affiliated with the China Central Television, called it a "a tower of sin" and "a symbol of the crimes of Japanese militarism", and called for it to be demolished.

Worked examples

Example 1 — a first encounter with Heiwadai Park

Start with the simplest possible case. Write down what Heiwadai Park claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Heiwadai Park before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Heiwadai Park ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Heiwadai Park

In research: Heiwadai Park appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Heiwadai Park in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Heiwadai Park is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 establishments in Japan, Buildings and structures completed in 1939, Miyazaki (city), so understanding it makes those chapters shorter.
In everyday life: Look for Heiwadai Park outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
