The Rinzai school (臨済宗; Japanese: Rinzai-shū, Chinese: línjì zōng) is one of the three Japanese Zen sects. Rinzai is the Japanese line of the Chinese Linji school, which was founded during the Tang Dynasty by Linji Yixuan (Japanese: Rinzai Gigen). Though there were several attempts to establish Rinzai lines in Japan, it first took root in a lasting way through the efforts of the monk Myōan Eisai, following his return from China in 1191. Eisai is thus usually credited with the transmission of Rinzai to Japan. The school may be said to have truly flowered, and achieved a distinctly Japanese identity, with Shuho Myocho (Daito Kokushi, 1283-1337) and Muso Soseki (1275–1351), influential masters that did not travel to China to study.
ZENZen is a school of Mahāyāna Buddhism, referred to in Chinese as Chán. Chán is itself derived from the Sanskrit Dhyāna, which means "meditation" (see etymology below).
Zen emphasizes experiential Prajñā—particularly as realized in the form of meditation known as zazen—in the attainment of awakening, often simply called the path of enlightenment. As such, it de-emphasizes both theoretical knowledge and the study of religious texts in favor of direct, experiential realization through meditation and dharma practice.
The establishment of Zen is traditionally credited to the Southern Indian Pallava prince-turned-monk Bodhidharma, who is recorded as having come to China to teach a "special transmission outside scriptures" which "did not stand upon words". The emergence of Zen as a distinct school of Buddhism was first documented in China in the 7th century CE. It is thought to have developed as an amalgam of various currents in Mahāyāna Buddhist thought—among them the Yogācāra and Madhyamaka philosophies and the Prajñāpāramitā literature—and of local traditions in China, particularly Taoism and Huáyán Buddhism. From China, Zen subsequently spread southwards to Vietnam and eastwards to Korea and Japan.

Japanese martial art associated with the smooth, controlled movements of drawing the sword from its scabbard, striking or cutting an opponent, removing blood from the blade, and then replacing the sword in the scabbard. While new students of iaidō may start learning with a wooden sword (bokken) depending on the teaching style of a particular instructor, many of those who study iaidō use an unsharpened sword (iaitō). Advanced practitioners of iaidō use a sharpened metal sword (shinken).
Because iaidō teaches the use of actual metal weaponry, it is almost entirely based on the teaching of forms, or kata. Multiple person kata do exist within some forms of iaido, but the iaidōka (practitioners of iaidō) will usually use bokken for such kata practice. Iaidō does not include direct competition or sparring of any kind. Because of this non-competitive aspect, and iaidō's emphasis on precise, controlled, fluid motion, it is sometimes referred to as "moving Zen."
Iaidō in North America and Europe is often taught in dojo that also teach Aikido, Aikibudo or Ken

Kenjutsu (剣術?), meaning "the art of the sword" [1]:172 , is a term for classical Japanese sword arts (or koryū), in particular those which predate the Meiji Restoration. It is sometimes used more generally to describe any martial art which makes use of the Japanese sword.
The exact activities undertaken when practising kenjutsu vary with school, but commonly include practice of basic techniques (kihon) without opponent and techniques where two persons paired kata (featuring full contact strikes in some styles). [2] Historically schools incorporated sparring under a variety of conditions, from using solid wooden bokutō to use of bamboo sword (shinai) and armor (bogu). [1]:XII, XIII In modern times sparring in Japanese swordsmanship is more strongly associated with Kendo.

Battōjutsu (抜刀術?) is a Japanese term meaning techniques for drawing a sword. It is often used interchangeably with the terms iaijutsu, battōdō, or iaidō, although each term does have nuances in the Japanese language and different schools of Japanese martial arts may use them to differentiate between techniques (e.g. standing or sitting techniques). The emphasis of training in battōjutsu is on cutting with the sword. All terms are somewhat more specific than kenjutsu or kendō which more broadly means simply sword techniques, and is often used to refer to techniques where the sword is already out of the saya
