The Kamiza or "spiritual seat" is the central focal point of the dojo and incorporates a number of necessary items. After a fashion addition personal or meaningful pieces can be added but the items noted here are the main stays of this powerful dojo talisman. First the Kamidana or shelf that holds the various items must be numerologicaly sound; the shelf must be three, six or nine feet long. It must be hung at a height using three inch increments as well for example 6'-3", 6'-6", 6'-9" and so on… any increment of three inches is "allowable". The Kamidana must also be positioned on the east wall of the dojo.

Next the Kamidana must have in its center a wooden housing that holds a "charged" calligraphy that has been blessed. This can vary depending on the dojo heads affinity for a specific personal direction, shrine connection or "objective". A small round mirror that represents the transitory and illusory nature of all things sits in front of the "spirit house". Sitting on each side of the spirit house are vases that hold greenery that represents man's eternal connection to nature and his place in it. On the front edge of the Kamidana are small candles that represent mans struggle to "return to the light". Those candles should number 3, 6 or nine - nine candles is the usual number said to reflect the nine schools of the Bujinkan Dojo. Above the Kamidana as one faces it is a picture or photograph of the current Soke Dr. Hatsumi and to the right the most recent past Soke Takamatsu Sensei. Directly below the kamidana and centered hangs a Shimenawa or "twisted rope" that signifies that the area has been blessed. Often small trays of rice and sake are placed on the Kamidana as well to represent an offering to the housed deities. These are the basic items.
Once the Kamiza has been completed the dojo and its kamiza are blessed in a ceremony known as a dojo Biraki. The Dojo Biraki ceremony utilizes the elements of offerings, smoke smudging, chanting and bell ringing.
