Ikegami Honmon-ji Temple

Overview

Ikegami Honmon-ji (池上本門寺) is a Buddhist temple of the Nichiren Shū, located in what is now Ōta-ku, suburban Tokyo. The temple was established in 1282, during the Kamakura period (1185–1333), in the fifth year of the Kōan era (弘安). It stands on the site where Nichiren, the founder of the Nichiren school of Buddhism, is said to have died.

The temple sits a short walk from Ikegami Station on the Tōkyū Ikegami Line or Nishi-Magome Station on the Toei Asakusa Line. Until the mid-20th century, the temple lay at some distance from the city of Tokyo. In 1907, the travel writers Basil Hall Chamberlain and W. B. Mason described it in these terms: "Its fine situation and magnificent timber make it one of the most attractive points within easy reach of Tōkyō."

History

Ikegami Honmon-ji was founded in 1282, the year Nichiren died. The temple was built at the place where the monk is said to have passed away, and it has remained a central site for the Nichiren Shū ever since. The original structures from the Kamakura period no longer survive.

The temple grounds were heavily damaged by the bombing of 15 March 1945, during the final months of the Pacific War. Most of the buildings that stand today were either reconstructed or newly built after that date. A few structures survived the bombing and remain in their original form.

One notable episode in the temple's modern history involves an American warship. The USS Oneida, a sloop-of-war launched in 1861, was rammed and sunk outside Yokohama by the British steamer Bombay on 24 January 1870, with a loss of 125 people. In May 1889, after a Buddhist ceremony was held in memory of the lost sailors, a memorial tablet for the sinking was placed at Ikegami Honmon-ji.

What Stands There Today

The temple complex contains several buildings of note, most of them rebuilt since 1945. The oldest surviving structure is the five-storey pagoda, built in 1608. It has been designated an Important Cultural Property of Japan and is the only building on the grounds that dates from before the Edo period.

Two other structures predate the 1945 bombing. The kyōzō (経蔵), a repository for religious writings, was built in 1784. The hōtō (宝塔), a type of pagoda, was built in 1781 and marks the spot where Nichiren was cremated. Both survived the wartime destruction.

The remainder of the buildings on the grounds have been either rebuilt or newly constructed since 1945. The temple also includes the Honmon-ji Temple Cemetery, which is part of the larger complex.

The Name in Japanese

The temple's name in Japanese is 池上本門寺, read in kana as いけがみほんもんじ. In romaji, it is written Ikegami Honmon-ji.

The name breaks down into four characters:

• 池 (いけ, ike) — "pond" or "pool." This character contributes the first element of the place name Ikegami.
• 上 (かみ, kami) — "upper" or "above." Together with 池, it forms the place name 池上 (いけがみ, Ikegami), meaning "above the pond."
• 本 (ほん, hon) — "origin," "root," or "true." In this context, it carries the sense of "original" or "principal."
• 門 (もん, mon) — "gate." The combination 本門 (ほんもん, honmon) refers to the "original gate" or "true gate," a term with specific doctrinal meaning in Nichiren Buddhism.
• 寺 (じ, ji) — "temple." This is the standard suffix for Buddhist temples in Japanese.

So the full name reads literally as "Ikegami Original-Gate Temple," with the place name Ikegami anchoring the temple to its location.

Visiting and Context

Ikegami Honmon-ji is accessible by two railway lines. Ikegami Station on the Tōkyū Ikegami Line is the closest stop, and Nishi-Magome Station on the Toei Asakusa Line is also within walking distance. The temple is now fully within the urban fabric of Ōta-ku, though its timber and hillside setting still give it the character that Chamberlain and Mason praised in 1907.

The most significant event on the temple's calendar is the O-Eshiki (お会式) festival, held from 11 to 13 October each year. The festival commemorates Nichiren's death and draws thousands of worshippers to the temple. The area between the station and the temple grounds fills with stalls and crowds during the three-day event.

A distinctive feature of the O-Eshiki is the mandō (万灯), an elaborate representation of a lantern stand carried through the streets. Participants also carry matoi, the tall, fireman's standard traditionally used in Edo-period Tokyo. The combination of the mandō and matoi makes the festival visually distinctive among Tokyo's autumn observances.

For a visitor, the temple offers a compact but layered experience: the 1608 pagoda, the 1784 kyōzō, the 1781 hōtō marking the cremation site, and the reconstructed halls from the postwar period. The cemetery, part of the temple complex, extends the site's history into the present. The memorial tablet for the USS Oneida, placed in 1889, is a quieter reminder of the temple's international connections in the late 19th century.
