The kanji image shows a "lantern insect" .
Their appearance along rivers of Japan brings a romantic, poetic feeling to all who watch them. And it did not cost the farmers a penny to go out and enjoy them.
The "fire" these animals emit is cold, though.
There are more than 40 different types of fireflies known in Japan.

Some say they are the vengeful spirit of Genzanmi Yorimasa 源三位頼政
(another name for Minamoto no Yorimasa), .
He was a warrior, leading the Minamoto armies at the beginning of the Genpei War. Suffering defeat, he committed suicide in the Byodo-in temple in Uji.

Some fireflies are named after the region where they were most beautiful and romantic to watch, in a historical setting.

Two special types of fireflies,
the Heike-botaru and the Genji-botaru 源氏蛍, are special kigo in Japan.
Heike-botaru, heikebotaru 平家蛍 - Luciola lateralis
Genji-botaru, genjibotaru 源氏蛍 - Luciola cruciata

To look at and catch fireflies was one of the common pleasures of the farmers since ancient times. Since the widespread use of farm chemicals, their number has greatly declined and nowadays many villages in Japan make special efforts to multiply these wonderful animals as an attraction for tourists and playground for the local children.

Calling the fireflies to come here in an ancient childrens song

こっち のみ-ずはあ-まいぞ、ホッホッ、ほ-たるこい

ho ho hotaru koi

Hey, fireflies, come here!
The water over there is bitter.
The water here is so sweet,
so come here, please, fireflies.

ho ho hotaru koi


From the Tale of the Heike


... The meadow glimmered with the light of a myriad glow-worms. Asagao smiled with sudden delight. Descending to the river she gathered the fireflies by scores, and, prisoning them in her veil, made a gleaming torch....

....The trembling girl crouched upon the balcony. Affrighted by the clash of arms, a swarm of fireflies rose from the river bank, soaring upon the night like sparks from a mighty conflagration.
The souls of the Minamoto!” cried Asagao despairingly. “Father, we are lost!”....

“A firefly in a prison pent,
Ne’er more to flame upon the moor.”

It is quite a long story within a LONG story!

Things found on the way

.. .. .. .. .. .. More Lore about the Fireflies

The below from F. Hadland Davis book,
"Myths and Legends of Japan" 1913 Unabridged

1. HAIKU, Page 285 (no source or Japanese text given)

Ah, the cunning fireflies !
being chased,
they hide themselves
in the moonlight

2. HAIKU, Page 285 (no source or Japanese text given)

From the Uji river-bank dart myriads of these flashing insects, and in a moment they form a great silver-shining cloud.
The cloud breaks and the flowing river, once dark as black, becomes a winding stretch of gleaming jewels.
No wonder the Japanese poet cries:

Do I see only fireflies drifting with the current?
Or is the Night itself drifting, with its swarming of stars?

3. GHOST LORE Page 286 (no source or Japanese text given)

Fireflies are fond of swarming around willow-trees, which are the most eerie trees in Japan, and this is part of their "ghostly" role as Minamoto Firefly and the Taira Firefly. In ancient days, the fireflies were said to possess medicinal properties.
Firefly ointment was said to render all poisons harmless, and, moreover, it had the power to drive away evil spirits and to preserve a house from the attacks of robbers.

4. STORY Page 287 Hadland (no Japanese text given)

Quoted from "Ancient Tales and Folk-lore of Japan," by R. Gordon Smith
Story called the Vengeance of Kanshiro.

A very old man named Kanshiro wants to make one last pilgrimage before he dies. His neighbors and friends all lend him some money to help him.
Along the way he is robbed by an inn keeper named Jimpachi. Kanshiro dies, but comes back from the tomb transformed into thousands of fireflies and the fireflies rush into Jimpachi's eyes, ears, mouth, and nose.
Jimpachi lives for 20 days, screaming for mercy. But no mercy comes, and finally the fireflies kill the wicked Jimpachi. Immediately thereafter, the fireflies disappear completely.

Issa and the Fireflies

草も木も 源氏の風や とぶ蛍
kusa mo ki mo genji no kaze ya tobu hotaru

in grass, in trees
the army of the Genji...
fireflies flit

(This haiku alludes to the historical battle between the Minamoto (Genji) and Taira (Heike) clans. The swarming fireflies remind Issa of a great army lighting campfires or carrying torches in the night.)

uma no he ni mezamete mireba tobu hotaru

the horse's fart
wakes me to see...
fireflies flitting

hatsu-botaru tsui to soretaru te kaze kana

the first firefly
deftly swerves away...
wind from my hand

"tsui to" can mean satto ("suddenly") or migaru ni ("with agility")

Issa calling for the fireflies

hotaru koyo hotaru koyo to yo hitori-zake

come, firefly!
firefly, come!
drinking alone

hotaru yobu yokogao yogiru hotaru kana

while calling fireflies
crossing his profile...
a firefly

hotaru yobu kuchi e tobi-iru hotaru kana

a mouth calling fireflies--
flies in

ao yagi ya hotaru yobu yo no omowaruru

green willow--
thinking of a night
of calling fireflies

hito-goe ya oobone otte tobu hotaru

people's voices--
with all their might
the fireflies flit

Literally, the firefly (or fireflies) are flitting with "bone-breaking" effort ... to reward the people who are calling.

koko hotaru ta-goto no tsuki to kurabe-ken

"I would like to compare
The glow of these fireflies and moonlight
Reflected in every paddy field"

(Matsuo Basho)

In 1688 (Genroku 1), Basho looked flying around fireflies on the surface of Seta River in Ohmi (The present Shiga Prefecture) on the way home. At that time, he remembered viewing the moon in Sarashina of Nagano, that was noted for "moonlight reflected in every paddy field" and composed this Haiku.

The whole district was called "The mount of Hime (princess)". 河野通有 Michiari Koono's uncle, Michitoki went to the war of Mongolian Invasions (of 1274 and 1281), leaving his only daughter "Hime" and he was killed in the Bay of Hakata.
Michiari carried his remains back to Hime waiting up her father. Hime had been staying at Gianji Temple 義安寺 and kept the grave of her late father throughout her life.

Princess Daruma Dolls at Temple Gian-Ji

Gian-Ji temple in Matsuyama is a zen temple, so it had been said that the origin of "Hime Daruma doll" is a tumbler of Bodhidharma on that Hime's face was drawn, to hold a memorial service for Hime.
Michiari was a samurai of Iyo (ow Ehime) and died in 1311.
The temple Gina-Ji had been build by the child of Kono Kagemichi 河野景通, Kono Shiroo Gian 河野彦四郎義安 in 1539.

Mitarai River flows under Gianji Temple from the front of Ishiteji Temple and it is famous for its Genji fireflies. There would be some fireflies that were pressed by catchers and went out in the hill at the back of the temple, that of the main gate had been already closed.

sanmon ni hotaru nigekomu shimari-nari

There would be some fireflies
Been driven away and went out in
the back-hill of the Temple

When one grows out thousands of seedlings, something special always pops up. ‘Pantaloons’ is such a special plant; the flowers are a light purple and shaped in a double ‘hose-in-hose’ like we’ve never seen before.

A rose-purple-dipped drink for the eyes! This is a tasty combination of red winter leaves (& wine-darkened summer leaves) topped with huge, rose-purple blooms. Easy to grow with a spreading habit. A sun lover of Japanese origin.

Under "things found on the way", it would be lovely to include a link to "Grave of the Fireflies", which I watched last night -- beautiful film.

Thanks for the page -- no fireflies here, and this brings them very close!

Kobayashi Issa

waga yabu wa jibun hazure no hotaru kana

in my grove
the fireflies appear
at a strange time

This hokku was written on 4/20 (June 6) in 1806, while Issa was staying for a few days with a student in Tagawa, a town on the Tone River just northeast of Edo. In this area the mating season for fireflies, that is, the two weeks when each variety flies around flashing its lights, is usually from the middle of May to the middle of June, depending on the variety. Issa seems to have come to town at a time when most people have been watching fireflies for two or three weeks already and the fireflies are beginning to thin out, yet in the garden of the place where Issa is now staying (or perhaps in a thicket outside Issa's window in a room in the house) the fireflies seem to have only just arrived.

The fireflies could be of a different variety of firefly from those that have appeared already, or breeding conditions and weather along the large Tone River might be variable, or perhaps the oddball fireflies are just as eccentric as Issa is.
