When the "nuki" is rectangular in section, it is called "Yasukuni torii", from Tokyo's Yasukuni Jinja. It is believed to be the oldest "torii" style.   (see illustration above) are gates found only at the Inner Shrine and Outer Shrine at Ise Shrine in Mie Prefecture. For this reason, they are also called "Jingū torii", from Jingū, Ise Grand Shrine's official Japanese name. There are two variants. The most common is extremely similar to a "shinmei torii", its pillars however have a slight inward inclination and its "nuki" is kept in place by wedges ("kusabi"). The "kasagi" is pentagonal in section (see illustration in the gallery below). The ends of the "kasagi" are slightly thicker, giving the impression of an upward slant. All these "torii" were built after the 14th century. The second type is similar to the first, but has also a secondary, rectangular lintel ("shimaki") under the pentagonal "kasagi". This and the "shinmei torii" style started becoming more popular during the early 20th century at the time of State Shinto because they were considered the oldest and most prestigious. The is a "myōjin torii" (see illustration above) with straight top lintels. The style takes its name from Kasuga-taisha's , or main "torii". The pillars have an inclination and are slightly tapered. The "nuki" protrudes and is held in place by "kusabi" driven in on both sides. This "torii" was the first to be painted vermilion and to adopt a "shimaki" at Kasuga Taisha, the shrine from which it takes its name. Almost identical to a "kasuga torii" (see illustration above), but with the two upper lintels at a slant, the first appeared during the Heian period. The name comes from the fact that this type of "torii" is often used at Hachiman shrines. The (see illustration above) is a "shinmei torii" without "korobi", with "kusabi" and a protruding nuki. It takes its name from Kashima Shrine in Ibaraki Prefecture. The is a "shinmei torii" built with unbarked wood. Because this type of "torii" requires replacement at three years intervals, it is becoming rare.
