changing rule

The mah-jongg of a new rule including the postwar years, intermediate reach, etc. or a U.S. style comes to be taken in, and the mah-jongg which was able to add the arrangement came to occupy the mainstream. Although China mah-jongg currently performed at prewar days was performed still now focusing on the Japanese mah-jongg league etc. which were rebuilt in 1947, from the mainstream, it separated from it gradually.

In 1965, Asada Tetsuya will start a series of the account series of mah-jongg wandering. Asada, Takeo Kojima, Furukawa and others will form a mah-jongg new compilation group in 1970. Modern mah-jongg was started in 1972 and the mah-jongg boom occurred. Many these time, and college students and salaried workers were familiar with mah-jongg as easy pocket-money earnings or a communication tool.

However, since unhealthy images, such as a gamble, smoking, and drinking, spread simultaneously, the Japanese healthy mah-jongg association aiming at abandoning them in 1988 and enjoying mah-jongg was established.

In 1990, Haruo Amano advocated exclusion of abstraction from a mah-jongg tactical theory in the "reach mah-jongg theory reformer" (Nagumo). The mah-jongg theory of famous mah-jongg pros of those days, such as an islet and Mitsuaki Tamura, Shoichi Sakurai and others out of government was criticized as it being the unscientific thing currently governed by abstract theory, such as "luck", "intuition", and a "flow", in it.

It was claimed that that Amano takes an abstract factor into consideration got used just to the cause which dulls appropriate information judgment, and it did not lead to progress of mah-jongg. This is the so-called forerunner of "digital player." Rank next with 2004 -- it came and northeastern "mah-jongg which carries out science" was published from the Kodansha present age pocketbook. Rank next -- what is called a "flow theory" to which it is supposed that the result of an office affects the next office before coming is denied thoroughly, and this work has also advocated the statistical mah-jongg strategy on the basis of probability theory.

The point which is guiding the stroke corresponding to the scene clearly and logically is the feature. There is also much mahjong player which thinks "luck", "intuition", and a "flow" as important to these digital mah-jongg, and such a tactical theory is called an analog and the occult. In addition, mahjong player belonging to neither digital one nor the occult also exists, an "RBI", "the damage given to a partner", "mental aggressiveness influence", etc. are thought as important, and it is called the "blow system."
