Kadomatsu are pine decorations placed at an entrance for New Year, commonly explained as markers for the visiting year deity. Paired pine-and-bamboo arrangements are familiar, but regional forms also include young pines with their roots attached.
Evergreen pine is associated with New Year congratulations and wishes for long life. Kyoto’s Gion tradition includes paired young pines retaining their roots, called nebiki-matsu. This example makes three bamboo stems an unsuitable requirement for defining every kadomatsu.
Another familiar form combines bamboo tubes of different heights with pine branches, a bound base and sometimes plum or other plants. Cuts and combinations vary locally; this is one arrangement rather than a construction checklist for every kadomatsu.
Shrine explanations commonly describe kadomatsu as signs or yorishiro for the visiting toshigami, the New Year deity. A yorishiro is an object in which a deity may be present. This explains the custom’s ritual setting without assuming that every household conducts an identical ceremony.
Gion’s local account describes paired young pines with their roots retained, tied with red-and-white mizuhiki and displayed with a doorway curtain bearing the house emblem. Pine, ties and curtain form the New Year entrance without requiring three diagonally cut bamboo tubes. Removing the pines and other New Year decorations also marks the end of the deity’s stay during matsu-no-uchi.
The traditional Shimoina form plants two wooden posts in the ground and adds pine, bamboo, sacred rope, paper streamers and an oyasu. The oyasu is a woven straw container described locally as the deity’s tableware; some households offer rice, zōni, red rice or porridge in it. It is not another name for a decorative bamboo tube.
The posts also connect New Year to agricultural work: posts cut from the mountains could later support racks for drying harvested rice.
Decorations remain for a New Year period called matsu-no-uchi. Removal dates differ: familiar seventh- and fifteenth-day practices are not a single nationwide deadline. Local practice also matters when disposing of plants or other materials.
Some communities gather New Year decorations for a sending-off or burning rite. In Tabayama, Yamanashi, the village’s account of Omatsuhiki describes New Year pine decorations being piled on a wooden sledge and drawn to a dōsojin wayside deity. It is evidence for that community’s practice, not the inevitable destination of every decoration.
Iida City’s record of Shimoina customs calls the late-December gathering of materials matsu-mukae. Before installation, white rice heaped in a one-shō masu measuring box, dried fish and citrus are offered before the pine and bamboo. The gathered materials pass through an offering and assembly before becoming the New Year entrance decoration.
The account preserves differences between households. The 29th is avoided as ku-matsu, associating it with suffering; some avoid the 31st as a last-night decoration, while others traditionally install theirs on that day. A particular household’s timetable does not establish a universal prohibition.
A 1999 botanical column at the National Museum of Japanese History cites the late-Heian song collection Ryōjin hishō describing pine set at a gate, linking it with New Year wishes for long life. Matsubayashi visits in the Nanbokuchō and Muromachi periods provide another related setting for congratulations involving pine; they do not establish one event as the origin of every arrangement.
Pine at the gate, gathering young pines and celebrations involving pine are related customs, but they do not establish one event from which every kadomatsu descends. Combinations of pine and bamboo also vary with locality and living conditions. Stories linking diagonal bamboo cuts to a famous person should be distinguished from documented arrangements.
Small entrance decorations, rooted pines and large paired arrangements can coexist. Household practice, available space and business settings shape what appears at a particular doorway. Identify the materials and local explanation before using size or appearance to judge authenticity.
Iida’s account describes traditional Shimoina decorations built around two wooden posts planted in the ground, with pine, bamboo, rope and paper ornaments. It links the newer local use of three diagonally cut bamboo stems to easier construction, visual impact and paved ground that makes posts difficult to plant. Even within one region, the familiar modern form was not the only arrangement.
Kōchi’s paper kadomatsu prints pine, bamboo and plum motifs on a sheet that is cut in half and attached on either side of the entrance. In an interview, Kyōwa Printing’s 酒井陽典 recalled that the company’s first proprietor began distributing it to neighbours around 1952, motivated partly by protecting pine woods and the New Life Movement. Kōchi City adopted it in 1954 and distributed it citywide from 1955 through 2004; neighbourhood organizations subsequently continued the activity.
Cutting and mounting turns one printed design into paired entrance decorations. Distribution also moved from a proprietor’s neighbourhood initiative into a municipal programme and then to local organizations.
Rooted young pines with red-and-white ties and an emblem curtain, without requiring three bamboo tubes.
Gathering in late December, offering rice and other items before the materials, then assembly and installation.
Some households avoid a last-night decoration, while others traditionally install it on the 31st.
A woven straw offering container used by some households for rice, zōni or porridge.
They could support rice-drying racks after harvest.
Paving makes planted posts difficult and favours readily assembled standing bamboo arrangements.
A late-Heian link between pine at the gate and longevity wishes, not one origin for all kadomatsu.
The sheet is cut in two and mounted beside the entrance. Neighbourhood distribution by its maker was followed by a municipal programme and later local organizations.
