FROM AROUND THE WORLD TO IWABITSU NINJA.
Sanada history, ninja culture and hands-on experiences. Families and groups from around the world can step into the world of Iwabitsu ninja.
ENGLISH-FRIENDLY NINJA EXPERIENCETake on VR sword battles, a spy infiltration mission, real shuriken throwing, authentic ninja artifacts and projection mapping. Challenge yourself, think, work with your allies, and discover your own “Ninja Power.”
The history of Iwabitsu. The strategy of the Sanada. The skills and spirit of the shinobi. Here, you do not simply observe the story — you become part of it.
Make NINPAKU part of your Japan journey. Located directly in front of JR Gunma-Haramachi Station, NINPAKU fits naturally into a trip from Tokyo, a Gunma onsen stay, a drive from Karuizawa or Nikko, or a winter journey through the ski areas around Kusatsu, Tsumagoi and Manza.
Travel times are approximate and vary with train connections, traffic and road conditions.
Add a ninja experience to your trip to Kusatsu, Shima or Ikaho Onsen. NINPAKU is indoors, making it an easy all-weather stop for families exploring Gunma.
Stop by on your way to the hot springs or on your journey back. NINPAKU fits naturally into a trip through Agatsuma and Gunma.
An indoor experience for any weather. Even when it rains, you can enjoy VR, shuriken throwing, exhibitions and immersive visual effects.
At NINPAKU, you do more than look. Take on the missions and put your own Ninja Power to the test.
VR, shuriken, infiltration, observation and real ninja culture. Step into the world of the shinobi and discover what you can do.
* Some experiences shown in this video may now be offered in a different format.
Enter a virtual sword fight and experience the legendary strength of Sanada Yukimura for yourself.
Admission includes one VR play per person.
Your play may be shared within your group. Additional plays are ¥200 each.
* For visual-safety considerations, the VR experience is not offered to children under elementary-school age.
Take aim and throw! Try authentic iron shuriken or child-friendly rubber shuriken. Admission includes 10 throws with either type. You can also throw origami shuriken freely at targets and villainous ninja appearing on the big screen. Test your accuracy!
Discover the real world of the shinobi through more than 300 ninja artifacts — one of Japan’s largest permanent displays. See shuriken, bo-shuriken, kusarigama, weighted chains, concealed trick weapons, scrolls and more. Some items can even be handled. In ninja costume, with authentic tools in your hands, the Sengoku era feels remarkably close.
Break through the traps spread across NINPAKU’s second floor and steal the hidden treasure! Step over, crawl under and weave through ropes fitted with bells — sometimes even jump. Your mission is to retrieve the old coin without sounding the alarm and return safely. Stealth, speed and your own ninja style decide the result.
Strength and speed alone do not make an elite ninja. Calm your mind, control your breathing and stack bottle caps with total concentration. It looks simple — until you try it. How high can you go? A quiet ninja discipline that tests the limits of your focus.
A two-minute illusion of light and shadow suddenly transforms the Ninja Artifact Gallery. Trick houses, flames, lightning-fast movement and the Sanada six-coin crest emerge around you as the world of the Agatsuma Sanada ninja comes alive. Young children may find the darkness and visual effects surprising.
There is even more to explore: retro ninja games, the “Ninbrary” ninja library, and ninja drawing activities.
Complete NINPAKU missions and measure six ninja abilities. Your results reveal your overall Ninja Power — and earn you a personalized certificate.
Speed, Skill, Vision, Knowledge, Spirit and Bonds. Your results determine your total Ninja Power and ninja rank.
