What is the length of a bamboo sword – Basic concept

The length of the shinai is an important element in Kendo that directly affects the performance of the technique and the progress of learning.

In this section, we’ll dig into the basics of Shinai length and its role in Kendo.

 

Basic explanation about the length of Shinai

A Shinai is a wooden sword used in Kendo practice and competitions.

Its length is chosen depending on the user’s height, physical strength, and skill level.

 

Generally, the length of a shinai is measured in shaku (shaku), which is approximately 2.5 shaku (approximately 75.8 cm) to 2.45 shaku (approximately 88 cm) for adult men, and approximately 2.3 shaku (approximately 69.6 cm) for women. It’s common.

When choosing the length of a shinai, the user’s arm length and ease of handling are also taken into consideration.

 

The role played by the length of the bamboo sword in Kendo

The length of the shinai greatly contributes to the reach, effectiveness of strikes, and defensive ability in kendo.

By using a shinai of the appropriate length, a kendo practitioner can learn more accurate techniques and maintain a proper distance from his/her opponent.

 

Additionally, the length of the shinai affects the power transmission and maneuverability during striking, and is also related to the degree of fatigue and efficiency of practice.

Beginners and children in particular can learn basic movements safely and effectively by starting with a shinai of a manageable length.

 

By deepening their understanding of these matters, kendo practitioners will be able to choose the optimal length of their bamboo swords and improve their technique.

The length of a shinai is more than just a number; it is closely related to Kendo techniques and tactics.

 

 

Standards and standards for the length of Shinai

There are domestic and international standards and official regulations regarding the length of Shinai to ensure that Kendo is practiced safely and fairly.

These standards have been established to help kendo practitioners select the appropriate bamboo sword and achieve optimal performance in competitions and training.

 

Domestic and international standards regarding the length of bamboo swords

Standards regarding the length of shinai in kendo are established by the International Kendo Federation (FIK).

This ensures consistency in international competition.

For example, the maximum length of a shinai for adult men is approximately 120 cm (approximately 3.9 shaku), while for women it is generally approximately 114 cm (approximately 3.7 shaku).

These standards are broken down into categories according to the size and gender of the participants, ensuring fair competition in each category.

 

Official regulations on the length of bamboo swords

Official regulations on the length of Shinai are also important as safety rules for Kendo.

This is to ensure that the Shinai used does not exceed the specified length, and the purpose is to provide an environment in which Kendo practitioners can safely hone their skills.

These regulations must be strictly adhered to, especially since the length of the shinai directly affects the reach on the opponent and the effectiveness of the blow.

Additionally, it is common for each Kendo federation or organization to establish specific rules for their own competitions and exams based on this.

 

Understanding and complying with these domestic and international standards and official regulations is essential for Kendo practitioners to compete and practice safely and fairly.

Choosing the length of the shinai that is appropriate for the user will help improve technique and ensure safety.

 

 

How to choose the length of a bamboo sword

When choosing the length of a shinai, it is necessary to consider the physique and skill level of the kendo practitioner.

Choosing the appropriate length of a Shinai sword is directly related to learning the technique and improving performance.

In this section, we will explain in detail how to choose the length of a shinai that suits your physique and how the length of a shinai affects your technique.

 

How to choose the length of a bamboo sword that suits your physique

The height and hand length of the kendo practitioner are important factors when choosing the appropriate length of the shinai. Please refer to the following guidelines:

  1. Proportional to height : Generally speaking, the length of the Shinai is proportional to the Kendo practitioner’s height. Check where the tip of the shinai touches the ground and determine if it is the appropriate length.
  2. Consider your arm length : When holding a shinai, it is important that your arm is naturally extended and relaxed. If you have to stretch your arms excessively, it’s probably too long.
  3. Physical strength and ease of handling : The length of the shinai also affects its ease of handling. Especially for beginners and young kendo practitioners, a length that is easy to maneuver is recommended.

 

Effect of Shinai length on technique

The length of the Shinai has a great influence on Kendo technique. Please note the following:

  1. Reach and striking effects : Longer bamboo swords increase reach, but can be difficult to manipulate. Using a shinai of the appropriate length allows for accurate and effective strikes.
  2. Defensive ability : The length of the shinai when defending affects the ability to properly pay off the opponent’s blows. Too long and it can be unwieldy, too short and it can be difficult to defend.
  3. Efficiency of practice : Using a shinai of the appropriate length will improve the efficiency of your practice and help you master the technique more smoothly.

 

Choosing a Shinai length that suits your physique is very important for improving your Kendo skills.

Please consider these points in order to choose a Shinai that suits your individual Kendo practitioner’s needs and achieve maximum performance.

    • It is recommended that the length of the shinai be chosen to suit not only the height of the user, but also the arm length and technical style. The general guideline for the ideal length is for the tip of the shinai to be a few centimeters above the ground when held.

 

Misconceptions regarding the length of Shinai and their correction

  1. Myth: A longer bamboo sword is always better

  2. Appearance customization : It is also common to customize the appearance of Shinai. By changing the color and design, you can express your individuality and increase the joy of ownership.
  3. Functional additions : The usability can be improved by making functional improvements, such as choosing a collar made of a different material or applying anti-slip treatments.

 

By appropriately adjusting the length of the Shinai and customizing it to suit your personal style and needs, you can maximize the effects of Kendo practice and lead a more fulfilling Kendo life.
