The world's smallest park

The world's smallest park is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand The world's smallest park rather than just read about it. In short: The world's smallest park (Japanese: 世界一小さな公園, Hepburn: Sekai-ichi Chiisana Kōen) is a park located in Nagaizumi, Shizuoka, Japan. Overview In 1988, the park was opened to utilize an extra space which was created during road construction.

Key takeaways

The world's smallest park belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect The world's smallest park to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of The world's smallest park from memory before moving on to harder problems.

Reference excerpt

The world's smallest park (Japanese: 世界一小さな公園, Hepburn: Sekai-ichi Chiisana Kōen) is a park located in Nagaizumi, Shizuoka, Japan.

Overview

In 1988, the park was opened to utilize an extra space which was created during road construction. There is a wooden bench, a black stone plate with a carving of flowers, and some vegetation in a 0.24 m2 (2.6 sq ft) square area surrounded by bricks. The park is smaller than Mill Ends Park in Portland, Oregon, which was formerly recorded as the world's smallest park on Guinness World Records. While Nagaizumi town used to state they have no intent to apply to Guinness World Records since the "park" is technically not a park but a part of a road, in 2024, they officially changed its designation to a park and started a project to apply for the world record. The fee for applying was around 2.5 million yen (equivalent to US$16,500) and the funds were raised by using the Hometown tax system. After a survey in January 2025, the land area was 0.24 m2 (370 sq in). Following this, the town formally announced the place as a park. The park was certified as a Guinness World Record, and an awarding ceremony was held on February 25 at Nagaizumi town hall.

Worked examples

Example 1 — a first encounter with The world's smallest park

Start with the simplest possible case. Write down what The world's smallest park claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 The world's smallest 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 The world's smallest 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 The world's smallest park

In research: The world's smallest park appears in science 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 The world's smallest 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: The world's smallest park is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1988 establishments in Japan, Nagaizumi, Parks in Shizuoka Prefecture, so understanding it makes those chapters shorter.
In everyday life: Look for The world's smallest 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.
