Kyoto Ninja Weapon Forging Experience: Make a Shuriken or Kunai

Forge Your Own Ninja Weapon in Kyoto

This approximately two-and-a-half-hour workshop at studio NIN Yase in Kyoto allows participants to forge their own shuriken or kunai from heated steel.

Rather than decorating a completed souvenir, guests heat, hammer, shape, quench, polish, and finish an individual ninja weapon.

The group activity supports both English and Japanese, and beginners receive guidance from experienced craftspeople.

The completed weapon can be taken home as a distinctive handmade memory of Kyoto.

Spend Approximately Two and a Half Hours Forging

The activity is presented with an approximate duration of two hours and thirty minutes.

After arriving at the workshop, participants choose a weapon and move through heating, forging, shaping, polishing, and finishing stages.

The workshop involves more steps than a compact decorative craft class and gives guests time to watch metal gradually become a recognizable ninja weapon.

Finishing times may vary slightly according to group size and individual progress.

Meet at studio NIN Yase

The experience takes place at studio NIN Yase in Kyoto.

It is presented as a join-in group activity with meeting at the workshop, so guests may work alongside other participants during the same session.

The quiet workshop setting provides space to concentrate while surrounded by the forge, hammers, grinding equipment, and metalworking tools.

Review the exact address, meeting time, and transportation route in the information provided before the activity.

Choose a Shuriken or Kunai

Participants choose from three shuriken styles or a kunai before beginning the forging process.

Different shuriken designs require different outlines and shaping methods, while the kunai has a distinctive elongated blade and handle.

Selecting the intended form at the beginning gives each stage of hammering and polishing a clear goal.

Available designs and workshop options may depend on the arrangements for the selected session.

Learn the History behind Ninja Tools

The experience also introduces the history and characteristics of shuriken and kunai.

Understanding the ideas behind these tools adds context to the physical process of making one.

Guests can look beyond the weapons seen in films and games and explore their connection with Japanese history and craftsmanship.

Heat and Hammer Real Steel

The central stage of the workshop involves heating real steel and repeatedly striking it with a hammer.

Under the instructor’s guidance, participants place the heated material on an anvil and gradually shape its outline.

Each hammer strike changes the metal and brings the selected shuriken or kunai closer to its final form.

Because the work involves sparks, heated steel, and specialist tools, guests must follow all instructions regarding position and technique.

Strengthen the Steel through Quenching

After shaping, the steel goes through a heat-treatment and cooling process.

This introduces participants to an important part of traditional metalworking rather than simply cutting a weapon shape from a sheet of material.

Temperature control and safety-sensitive stages remain under the direction of experienced craftspeople.

Guests can observe how heat treatment helps transform the shaped metal into a finished object.

Polish and Finish the Weapon

The forged and heat-treated steel is then polished to refine its surface and outline.

Participants gradually smooth the material and bring out the recognizable form of a shuriken or kunai.

Hammer marks and variations created during the handmade process give each finished piece its own appearance.

Depending on the selected session, engraving or additional finishing may also be available.

Take the Completed Ninja Weapon Home

The completed ninja weapon is presented as a handmade souvenir that participants may take home.

Unlike a mass-produced gift, the finished piece preserves the memory of heating steel and working with a hammer in the Kyoto forge.

Store and transport the item securely while traveling.

Guests flying with it or taking it internationally should review airline, transit-location, and destination-country regulations concerning blades or weapon-shaped objects.

Guidance in English and Japanese

The booking information currently lists both English and Japanese as supported languages.

International visitors can receive explanations about the process and safety requirements while participating.

Guests with a preferred weapon shape or questions about specialist terms can speak with the instructors before beginning.

Instructors support each participant according to their progress during the group workshop.

Suitable for First-Time Metalworkers

The activity is designed to accept participants without previous forging or metalworking experience.

Instructors explain how to hold the tools, where to strike the steel, and how to move through the polishing stages.

Participants are not expected to complete every advanced or safety-sensitive process without assistance.

Professional support makes it possible for beginners to join authentic steps and experience the satisfaction of completing an individual weapon.

How It Differs from Kyoto Knife Making

The authentic Kyoto knife-making workshop focuses on forging a practical iron knife that can be used as a tool.

This experience instead creates a shuriken or kunai connected with ninja culture and includes the history and characteristics of the selected weapon.

Travelers seeking a practical blade may prefer the knife workshop, while guests interested in ninja culture and forging together may prefer this experience.

Those wanting to observe a working Japanese swordsmith and spend longer exploring blade making can compare the Aioi swordsmith demonstration and samurai knife-making experience.
