I was well welcomed. I arrived in the middle of a training session and Saw all their techniques. The people were very friendly, the master was funny and very humble. Even though you feel like you are an intruder in their sacred dojo with your foreigner clothes, manner and language they do their best to make you feel at ease.
Then was my Time. The training was fast and i was rapidly put to the task of cutting the bamboo which is a unique experience. Now you know what a Real Sword Can do, and it IS very sharp. you feel more authentic in the Armor, and that also makes better photos/videos. The fact that the teacher gives you his Sword to use, and explains his origins and story then you watch all the process of cleaning adds to the expérience. And don't try to touch the blade, i dont know if its rude or dangerous or both but they won't permit it.
To sum it up, it is an authentic experience, original, humbling, intimidating, but very fun experience, and the people in the dojo were awesome. Worth every penny. You Can skip the Armor if you're tight on budget but it is more immersive and makes a perfect souvenir. Highly recommend it.
