One character writing - ichijikakidashi

One of the ancient document styles. It is also called Ichijijo, Myojijo, or Kakanjo. It is a document given as evidence when an Eboshi-oya (parent of a hat-wearing father) gives one character of his own given name (part of his given name) to name his child on the occasion of Genpuku (coming-of-age ceremony). It is not limited to parents and children wearing Eboshi hats, but was also used between lords and vassals to strengthen feudal lord-vassal relationships. It was especially popular during the Muromachi and Sengoku periods. It may be accompanied by a soejo (attached letter), but when it is written on a single sheet of paper, it usually consists of one character of the given name, the date, the sender (signature and seal), and the addressee.

古文書様式の一つ。一字状、名字(みょうじ)状、加冠(かかん)状という場合もある。元服(げんぷく)に際し、烏帽子親(えぼしおや)がその子の命名に自分の諱(いみな)の一字（偏諱(へんき)）を与えるとき、証拠としてその一字を記して与えた文書をいうが、烏帽子親子にとどまらず、封建的主従関係の強化を目的として主君従者間でも行われた。とくに室町・戦国期に盛行した。添状(そえじょう)を伴うこともあるが、一紙にまとめる場合は偏諱一字、年月日、差出（署名花押(かおう)）充所(あてどころ)からなっていることが多い。
