A is a hall or place for immersive learning, experiential learning, or meditation. This is traditionally in the field of martial arts. The term literally means "place of the Way" in Japanese.
The word dà Âjà  originates from Buddhism. Dà Âjà Âs were often adjunct to temples and were formal training places for any of the Japanese arts ending in "-dà Â", from the Chinese Dao, meaning "way" or "path". Sometimes meditation halls where Zen Buddhists practice zazen meditation were called dà Âjà Â.
The alternative term zen-do is more specific, and more widely used. European Sà Âtà  Zen groups affiliated with the International Zen Association prefer to use dà Âjà  instead of zendo to describe their meditation halls as did their founding master, Taisen Deshimaru.
Other Buddhist traditions also sometimes met in private dà Âjà Âs which were not part of a temple. For example, the Jà Âdo Shinshà « school initially began as networks of dà Âjà Âs where followers of all classes would meet. These were usually small buildings, often private residences turned into chapels for religious chanting of the nembutsu and other monthly services. Rather than complex altars, they used vertical scrolls with calligraphy as the main object of worship.
In Japan, any facility for physical training, including professional wrestling, may be called a dà Âjà Â. In the Western world, the term dà Âjà  (when related to physical activity) is used exclusively for Japanese martial arts such as aikidà Â, jà «dà Â, karate-dà Â, etc.
A proper Japanese martial arts dà Âjà  is considered special and is well cared for by its users. Shoes are not worn in a dà Âjà Â, which is in line with the Japanese custom to keep the premises clean and respectable. In many styles it is traditional to conduct a ritual cleaning (sà Âji; æÂÂé¤) of the dà Âjà  at the beginning and/or end of each training session. Besides the obvious hygienic benefits of regular cleaning it also serves to reinforce the fact that dà Âjà  are supposed to be supported and managed by the student body (or by special students, e.g., uchi-deshi). In some cases, the instructional staff may choose to help the students clean, as a sign of modesty, setting a personal example. In Modern Times, even when a school has a Dojo to train inside of, the training may sometimes be conducted outside, often in parks.
Many traditional dà Âjà  follow a prescribed pattern with shomen (æÂ£é¢; "front") and various entrances that are used based on student and instructor rank laid out precisely. The Shomen is designated as a wall, usually in the North of the Dojo and facing the entrance. Typically students will enter in the lower-left corner of the dà Âjà  (in reference to the shomen) with instructors in the upper right corner. Shomen typically has a shelf attached to it. On the shelf would traditionally be presented a miniature Shintà  shrine with a sculpture, flower arrangement, or other artifacts. Pictures of past Masters are generally found aside the shrine, and not on it. The term kamiza means "place of honor" and a related term, kamidana refers to the shrine itself. Other artifacts may be displayed throughout the dà Âjà Â, such as kanban (çÂÂæÂ¿; signboard) that authorize the school in a style or strategy, and items such as taiko drums or armor (à Â-yoroi). It is not uncommon to find the name of the dà Âjà  and the dà Âjà  kun (roughly "dà Âjà  rules") displayed prominently at shomen as well. Visitors may have a special place reserved, depending on their rank and station. Weapons and other training gear will normally be found on the back wall.
A honbu dà Âjà  (æÂŽÂ¨éÂÂå ´) is the central training facility and administrative headquarters of a particular martial arts style.
