Introduction

Mii-dera (formally Onjo-ji) is one of Otsu's major temples and a real center of one branch of Japanese Tendai Buddhism. We reviewed a recent travel vlog's cherry-blossom-season walk through the temple grounds and checked the history behind what it showed.

A Major Temple With a Real Split History

Mii-dera was founded in 672 and is the head temple of the Tendai Jimon school — a branch that split from the Sanmon lineage centered at Enryaku-ji on nearby Mount Hiei in 993, following followers of the monk Chisho Daishi Enchin. That schism is a genuinely significant event in Japanese Buddhist history, not a minor sectarian footnote, and it's part of why Mii-dera exists as a large, independent temple complex rather than a subordinate site.

Where the Name Actually Comes From

"Mii-dera" translates roughly to "temple of the sacred well" (some sources render it "temple of the three wells"), and the name has a specific documented origin: a spring inside the temple grounds is said to have provided the water used in the first ceremonial bath (ubuyu) of three 7th-century imperial figures — Emperor Tenji, Emperor Tenmu, and Empress Jito. It's a genuinely unusual case where a major temple's name directly commemorates a specific historical water source still present on site, rather than being a purely descriptive or honorific name.

The Kondo: A National Treasure

The temple's main hall, the Kondo, was rebuilt in 1599 with funding from Kita no Mandokoro, the widow of the powerful daimyo Toyotomi Hideyoshi, and is designated a National Treasure. Its cypress-bark (hiwadabuki) irimoya-style roof is a hallmark of high-status traditional Japanese temple architecture.

A Pagoda's Long Journey

The three-story pagoda on the temple grounds has real, documented, and unusually well-traveled history: it originally stood at Hiso-dera (present-day Sesonji) in Yoshino, Nara. Toyotomi Hideyoshi had it relocated to Fushimi Castle in 1594; Tokugawa Ieyasu then donated it to Mii-dera in 1601, where it has remained since. It's a designated Important Cultural Property.

The Sutra Storehouse and Its Rotating Shelf

The temple's Issai Kyozo sutra storehouse houses an octagonal rotating shelf (rinzo) built to hold Buddhist scriptures — the building itself was relocated to Mii-dera from Kokusho-ji in Yamaguchi in 1602 under the daimyo Mori Terumoto. The rotating shelf is a protected cultural property and isn't something visitors can actually turn today, whatever its original function.

The Once-Every-33-Years Statue

The Kannon Hall's principal image, a Nyoirin Kannon statue, is an Important Cultural Property that is normally kept hidden and shown to the public only once roughly every 33 years — a real tradition (not a marketing claim), consistent with several other secret-Buddhist-image ("hibutsu") traditions found at major Japanese temples. It has occasionally been specially opened outside that cycle for major national events, such as the 2019–2020 imperial enthronement.

Suikanji: The Cat Sub-Temple

Suikanji, a small sub-temple near Mii-dera's gate, is genuinely known locally as a "cat temple," selling ceramic maneki-neko-style fortune sets. The claim that proceeds specifically support cat rescue activities appears repeatedly across Japanese travel blogs and visitor accounts, but we could not confirm it against an official temple or government statement — we're presenting it here as a widely reported visitor claim rather than a confirmed fact, so treat it as likely but unverified.

The Bell a Warrior Monk Allegedly Stole

Mii-dera's bell tower houses a real, well-documented legend: the warrior monk Benkei — later famous as the loyal retainer of the 12th-century warrior Minamoto no Yoshitsune — reportedly stole the temple's bell (weighing close to half a ton) during a dispute and dragged it up nearby Mount Hiei in a fit of anger. The story has been depicted repeatedly in Japanese art and theater over the centuries, including Noh plays, bronze sculptures, and netsuke carvings held in museum collections outside Japan. Separately, and on firmer historical footing, the temple's own bell tower houses the "Evening Bell of Mii," one of the classical "Eight Views of Omi" — a set of scenic locations around Lake Biwa that inspired generations of Japanese woodblock artists, including Hiroshige. Treat the Benkei theft story as a well-documented legend rather than verified history, and the Eight Views designation as the more solidly historical fact of the two.

Practical Tips

• The Kannon Hall's viewing platform requires a reservation and extra fee, as the source vlog notes — decide in advance whether the Lake Biwa view from that platform is worth the extra step for your visit.

• Multilingual signage throughout the grounds makes it easier to follow the temple's layered history without a guide.

• If cat-themed omikuji interest you, Suikanji is easy to miss since it's a small sub-temple rather than the main complex — look for it near the entrance gate specifically.

Sources and Verification Notes

Mii-dera's founding date, Tendai Jimon lineage, the Kondo's National Treasure status, the pagoda's Nara-to-Fushimi-to-Otsu relocation history, and the Kannon Hall's 33-year viewing tradition were checked against the temple's own museum records and independent travel-history references. The sacred-well name origin and the Benkei bell legend / Evening Bell of Mii were independently verified against travel-history sources; the Benkei theft story is presented explicitly as legend rather than documented fact. The Suikanji cat-rescue charity claim could not be verified against an official source and is explicitly flagged above as unconfirmed.
