Mizuya (水屋) is the term for the preparation area in a Japanese tea house () or attached to any venue used for the Japanese tea ceremony. For instance, the area used for preparation during outdoor tea ceremonies is also called the. The term can also refer to purificatory fonts at shrines and temples, as well as to storage cupboards for use in kitchens. This article, however, focuses on the tea ceremony .

History
The full development of chadō (the Japanese "Way of Tea") and advent of the independent structure dedicated to and designed for use for this cultural activity is generally attributed to the sixteenth century tea master Sen no Rikyū. With the development of a structure dedicated to receiving guests for this cultural activity, there naturally was the need for a "back room" area for the host to make ready the items to be used for the reception of the guests. Before this, during the early development of the Japanese tea ceremony, corners of large reception rooms were partitioned off for tea-making, and there was no specific area or space designed for the preparations. According to A. L. Sadler, the earliest extant example of a space attached to a (room intended for the tea ceremony) that is describable as a  exists at the Taian, a  designed by Sen no Rikyū. are also mentioned in writings by Sen no Rikyū's chanoyu (tea ceremony) mentor, Takeno Jōō.

Use
As its name suggests, a provides a location for the performing of tea ceremony-related tasks involving water, such as washing the various utensils and supplies, and boiling extra water for filling and replenishing the pot in the tea room. A is also used for the final preparation of wagashi that will be served during a chanoyu function (such as cutting them, arranging them on dishes, and so on); for organizing, preparing, and (in some cases) storing the tea supplies; and, in the case of functions for large groups of people, for quickly preparing many bowls of tea to serve to guests.

Facilities
The most modest modern may comprise little more than a hot-plate or electric kettle and several buckets of fresh water, and might be located in a screened-off outdoor area with a grass floor. A fully equipped modern indoor may rival the best-equipped kitchen, with several sinks with hot and cold running water, an elaborate system of storage areas, cupboards, shelves and worktops, a refrigerator, stove, and microwave oven. In practice, however, most fall somewhere in between.

A typical indoor has in it a recess three or four feet wide and two feet deep, the, possibly with a tatami mat in front of it, equipped with a traditional sink, the  (a long metal tub sunk into the floor and covered with a bamboo grate called ), several wooden shelves for storing tea supplies, and a board with pegs for hanging ladles and towels. Where there is no permanent built-in with these facilities, a portable unit called an okimizuya may be used. There are manufacturers of such units. Whatever the style and size of this area, it will be kept scrupulously clean and organized, each school having its preferred order of arranging the utensils.

The special
Some tea rooms may have a special type of built-in recessed cabinet called mizuya dōko (水屋洞庫). It is built into the wall of the tea room, at floor level, on the side where the host's mat is situated, and has sliding doors so that it can be closed from view of the guests. A plain lacks the water drainage facility that a ' features, and therefore functions differently from a . Both  and ' are innovations meant for the use of hosts who have difficulty walking and getting up and down from the seiza sitting position, such as the elderly in particular.

According to A. L. Sadler, the name is taken from the boxes in which strolling puppeteers kept their dolls, and was first borrowed by Sen no Rikyū. were first placed on the floor, then hung on the wall, and finally built in.
