(anon continues) Poison in the dyeing process, like when green dresses were dyed with copper arsenite and it was extremely deadly.

Or a pattern of someone being poisoned, like a historical/folktale.

_______________________________________

Thank you for your kind words <3 I tried to keep things organized but the subject is huge so my of the top of my head answer is going in many directions. I hope you’ll still find what you need :3

I’ll briefly cover here dyes and (pigments), poison motifs, real life and supernatural poisonings. Buckle up we’ve got a long post ahead!

____ ABOUT DYE

Tbh I had to think for a moment because I don’t recall major “poison” stories linked to dyes in Japan, be it fictionous or real (yet that doesn’t mean none ever happened, especially considering Japan’s history of industrial poisonings…).

Most gruesome details in the fabric industries I know of are about the horrific life & work conditions of female laborers in spinning mill manufactures (as in many countries, Japan industrialization process was ghastly…).

If potters and dyers had excellent practical knowledge, chemistry as a science officially started kind of late in Japan as it was not a local interest, and as rangaku (study of Western knowledge) often favored other subjects like medicine or warfare.

So, until the introduction of aniline dyes (not textile related, but this article about the use of synthetic dyes in ukiyoe printing is super interesting), Japanese worked with “natural” dyes, like ai (indigo) which was the most used during Edo period.

As with any ingredient, being natural doesn’t equal safety. Some mixtures could be quite potent/foul, and process could be dangerous. Plants and minerals base ingredients could be toxic (cinnabar and orpiments were then used as paint pigments, and lead could be found in make up), as were mordants used to set colors.

If you want to easily overview which ingredients were used to create colors, I recommand browsing [Irocore] which presents colors with explanation in English in their database (pick a color then scroll down).

Not related to poison, but ai (indigo) is traditionally prepared in aigame/enormous floor set jars I find utterly terrifying:

I don’t know if this tidbit can help you, but some dyes and mordants actually damage the fabric overtime, leaving them brittle (silk desintegrates after a while which is a huge issue in textile conservation).

____ POISON MOTIFS

Concerning “poison” themed patterns, none would be actually used traditionally on a kimono or an obi beside novelty items ^^;

For example, many plants can be toxic, but I don’t see them set as pattern for this property - they’d rather refer to a poem, be a symbol of the passing of seasons etc. Fuji (wisteria) can be quite harmful, yet it’s a beloved traditional motif in Japan.

You have much more chances to find pattern with kujaku (peacock) which are thought to be impervious to poison in Buddhism, than say venomous mukade (centipede) or the horrific ômukade (a youkai I covered in a folktale).

Snakes like the habu and mamushi are dangerous, but if used as pattern snakes are most often auspicious and linked to rain dragons or goddess Benzaiten.

If you squint hard, toxic fugu could count as poison pattern, but such a seasonal delicacy as a motif would mostly underline wealth (as those fishes are pretty expensive as they are prepared by specialized chefs), a kind of carpe diem spirit, or just a fun pattern because fugu balloon shape is cute ;)

____ POISON MURDERS

Poisoning was certainly a thing is Japan since ancient times (see kodoku sorcery). Poisons were for example used in some fishing techniques.

I am pretty sure some kuge and buke were disposed of this way - even thought poison was seen as a coward weapon (hence why its supposed to be only used by shinobi/ninja - even if this “fact” is opened to a lot of discussions!).

During Edo period, such murders made up the news and penny dreadful-like illustrated books favored by city dwellers in need of a fright. But those stories didn’t pass to posterity beside cheap ukiyoe plates, and were never as popular as some shinjû (double suicides) or ghost revenges like poor poisoned and murdered Oiwa’s:

____ SUPERNATURAL POISONINGS

If your poison is both physical and metaphorical illbeing, mushi could be your guys ^^ This term actually covers everything small and crawling, from real worms and insects, to anything inside one’s body causing distress - be it a parasite, an unknown illness, an overboard emotion, a curse etc. If you’ve read/seen Mushishi you’ve got what I mean:

In fact any illness-causing being could count as poison-bringer. Hôsôkami (smallpox demon) was truly feared by all before vaccination was introduced in Japan.

Finally, continuing the supernatural poisoning trail, best girl is probably legendary fox witch Tamamo no Mae who among other terrible deeds made emperor Konoe fall sick with poisonous miasma (some version of the story attributes the disease to another monster, the nue). I covered a similar murderous kitsune folktale here.

Mesmerizing snake patterned kimono and hanhaba/fukuro obi by Gofukuya. Pattern being on same scale (ah!) for kimono + obi gives an amazing effect!

Sorry for this non-kimono related post but: SNAKE CUFFLINKS!!!

Those are from luxury jewelry creator Schun Hinami, and that design is to die for!

White snake themed outfit by Gofukuya (also exists in furisode version).

The white snake is the sacred animal of goddess Benzaiten (or Benten), the Japanese version of Hindu goddess Saraswati, ruling over “everything that flows: water, time, words, speech, eloquence, music and by extension, knowledge”. In Japan, the biwa luth (depicted here on the obi) is thought to be her favourite instrument

Kiyohime crossing the Hidaka river, powerful art by Miki Katoh (seen on)

This piece show a variation of the Kiyohime myth. Usually the snake transformation takes place at the Dojoji temple  - it’s the version featured in kabuki play Musume Dojoji.

The variation tells that Kiyohime, enraged by the monk Anchin rejection, transformed into a snake/dragon while swimming across the raging Hidaka river. (This take is super interesting as dragon/snakes are usually linked to water bodies in Asia.)

This transformation is heavily pictured in art, like in this famous ukiyoe by Yoshitoshi Tsukioka (the uroko kimono pattern depicts snake/dragon scales):

Young jimuguri (burrowing rat snake​ /Japanese forest rat snake), pic taken by Momo.

Those super shy snakes are pretty common in Japan and as their name suggests, they sleeps in burrows and prey on rodents by nightfall (they are super important for ecosystem!). Despite their vivid color they are not venomous :)

I had never realised how pretty their bellies are with that check pattern!
