Japanese terms for guns?

[Bhu]

I'm revising my samurai/ashigaru class and need to know feudal terms for guns. All I can find is Teppo, which I'm sure refers to teh Arquebus, but what would they call other firearms?

On a more useful note, the feudal colloquial term for all firearms was tanegashima, after the place where the Portugese first landed.

If you're after more detailed terms, then the Wikipedia page on Arquebuses (http://en.wikipedia.org/wiki/Arquebus) has some links to Japanese hand cannons, pistols and the like.

Firearms of Japan (http://en.wikipedia.org/wiki/Firearms_of_Japan) may also be of some use, although if you're after modern terms, a dictionary may be of more use.

[Bhu]

Google, yo.

Google gets me the term Teppo. Thats about it. Hence why i took the chance of asking of someone here might be more knowledgeable

Much thanks to Brother Oni :smallcool:
Now I just need to find stuff for explosives and cannons

[factotum]

Isn't the name of the famous Buriza-Do Kyanon from Diablo 2 Japanese for "Blizzard Cannon"? Sure I remember reading that somewhere...

[Yanagi]

A quick runaround on Wikipedia:

Tanegashima are matchlock long guns based on those seized from the Portugese. From there develop a range of arquebuses (http://en.wikipedia.org/wiki/Arquebus)matching different strategic needs: ozutsu hand cannons for use against formations, bajozutsu as equestrian weapons akin to carbines, and tanzutsu pistols. All of these varieties circulated during the Sakoku period, though their production and distribution was heavily regulated by Edo: gunnery, though, was a legitimate-if-obscure aspect of bujutsu to study.

I'm not an expert, so I don't know if that's comprehensive or accurate picture of types.

[Bhu]

Thanks!

I should prolly start posting a list of weapons eventually. I also need to find a name for a dagger hidden inside a jutte because apparently they were made but i cant find an official name for them

[SiuiS]

isn't a jutte just a bar with a prong? It's a dagger-like weapon itself...

Aiguchi? It's a catchall term for dagger without quillions or the like, I think. I've seen it applied to shivs before. There is also Shikomi-Zue, which I've seen applied to swords hidden in canes, sticks with retractable/extendable blades, etc.

This is all admittedly from flawed memory though.

[Bhu]

pretty much, but im wondering what to calle one with a hidden blade

Shikomi-zue were canes or walking sticks hiding various weapons, including swords, chains, spear tips, hooks, etc. I wanted to somehow differentiate from them.

[Mando Knight]

Isn't the name of the famous Buriza-Do Kyanon from Diablo 2 Japanese for "Blizzard Cannon"? Sure I remember reading that somewhere...

...It's the Gratuitous Japanese of the Gratuitous English for Blizzard Cannon.

[factotum]

...It's the Gratuitous Japanese of the Gratuitous English for Blizzard Cannon.

Me stooopid, not know what talky man means...

[CarpeGuitarrem]

...It's the Gratuitous Japanese of the Gratuitous English for Blizzard Cannon.
Quite so. I've become very adept at speaking Gratuitous Japanese XD.

For example, the Eekke Faatesseben.

[Mando Knight]

Me stooopid, not know what talky man means...

Gratuitous Japanese (http://tvtropes.org/pmwiki/pmwiki.php/Main/GratuitousJapanese): Stick in the Japanese for a phrase just because you can.
Gratuitous English (http://tvtropes.org/pmwiki/pmwiki.php/Main/GratuitousEnglish): The same, but for English.

Buriza-Do Kyanon: An approximate romanization of the katakana used to write "Blizzard Cannon."

[Prime32]

Buriza-Do Kyanon: An approximate romanization of the katakana used to write "Blizzard Cannon."Basically, it's "Blizzard Cannon" with a Japanese accent.

To give more detail, Japanese words are built from a different set of sounds to English, with the sounds Bu-ri-za-a-do Kya-no-n being as close as you can get to the original.

[Bhu]

does anyone know if the following exist or their just bull:

Sode Tsutsu: primitive one use shotgun

Jirai or Jiraika: primitive land mine

Shikoro: saw bladed knife or sword

Neru Kawaito/Neru-Kawa ito: Laminated wood/leather shield

Dokuenjutsu: poison smoke grenades

Gobo: wooden club

Chosen Jitte: basically a chain whip

[Knight9910]

Sadly the only Japanese gun I know of is the tanegashima. ^^;;

Well, I don't know for a fact, but I will try to help. Wikipedia has nothing on any of them, though it might be that you have the wrong names...

I have heard of a jitte (or jutte) but it's not even remotely a chain whip.
http://en.wikipedia.org/wiki/Jutte

As for the Gobo, are you thinking of a kanabo?
http://en.wikipedia.org/wiki/Kanab%C5%8D

The closest I've found to the jiraika is the fougasse, which is...probably not what you're looking for.
http://en.wikipedia.org/wiki/Fougasse_%28weapon%29
Alternately, read the "History" section of this article:
http://en.wikipedia.org/wiki/Land_mine

I don't think the shikoro-ken (saw sword) is a real historical weapon, but I have seen plenty enough stuff on sword collector websites to say you should be fine using it.

Don't know much about the neru-kawa ito, however I do know that wood shields with leather over them are real things that have been used in history.

For the dokuenjutsu, again, I don't know about the name, but according to Wikipedia:

Explosives introduced from China were known in Japan by the time of the Mongol Invasions (13th century).[92] Later, explosives such as hand-held bombs and grenades were adopted by the ninja.[83] Soft-cased bombs were designed to release smoke or poison gas, along with fragmentation explosives packed with iron or pottery shrapnel.[67]

[DeadManSleeping]

Jirai or Jiraika: primitive land mine

Jirai(ka) is indeed the modern Japanese word for land mine. However, I know of no historical Japanese landmines. That was the Chinese.

EDIT: As for "gobo", the second syllable is indeed the syllable for "club" or "stick", but I can't find any permutations with that first syllable. Of course, I didn't look too hard.

[Brother Oni]

Sode Tsutsu: primitive one use shotgun
Jirai or Jiraika: primitive land mine


I remember seeing primitive firearms and explosives at the Iga-ryu Ninja museum (http://iganinja.jp/en/), but I couldn't tell you what their names were. That said, I do remember a blunderbuss type weapon so a one use shotgun isn't unrealistic and grenade-like explosives, so remotely detonated or timed landmines rather than more modern pressure-plate ones would be suitable.

However these were specifically at a ninja museum - whether samurai or ashigaru would use them (or have the know how) is dubious.



Neru Kawaito/Neru-Kawa ito: Laminated wood/leather shield


Further to Knight9910's comment, as far as I know, these shields would have been used more like pavise (http://en.wikipedia.org/wiki/Pavise) or siege shields to shelter infantry from enemy arrows, rather than in hand to hand combat.

[H Birchgrove]

Japanese sub-machine guns goes like "Baka baka baka baka baka baka baka". :smalltongue:

[Bhu]

As for the Gobo, are you thinking of a kanabo?
http://en.wikipedia.org/wiki/Kanab%C5%8D



Nope. Kanabo are reinforced with iron. The Gobo is just a plain wooden warclub. Probably a fairly primitive weapon, or something of last resort.

[danzibr]

[CarpeGuitarrem]

Japanese sub-machine guns goes like "Baka baka baka baka baka baka baka". :smalltongue:
The word you want is "dakka", not "baka". :smalltongue:

[Bhu]

Any of you heard of Hyakurai? I keep seeing references to a primitive explosive, or several guns detonated in a barrel to cause noise and sow fear and confusion.

Also what about these :

Arare: 3 dimensional shuriken basically

Bakuchi Ire: bamboo tubes filled with gunpowder. Basically noise bombs.

Bakurai bishi: Caltrops containing minor explosives (sounds like bull to me)

Hi-kyu: Hollow clay ball filled with gunpowder

Hi-ya-zutsu: Bamboo tube used to shoot fireworks of flaming arrows.

Kame baku: Spiked iron shell filled with gunpowder.

Mitsu te: Pole attached to a chain with several hooks at teh other end.

Nage-gama: Throwing sickle?

Nage-ken: Small throwing sword (wtf?)

Seiryu-to: Sort of like a machete

Sode-teppo: Crude one shot gun made from a bamboo tube.

Suikan: Bladder filled with irritant, poison, or mild acid connected to bamboo blowtube.

Tabi-Yumi: Traveling bow, a collapsible shortbow with very short range.

[DeadManSleeping]

It would help us all a lot if you would tell us where you're seeing these things. Most of it, however, seems to be stuff that has been made up in modern times. I'll list the exceptions, or stuff of note, at least.

Bakuchi ire: The word "bakuchiku" refers to a firecracker stored in a bamboo tube. I can't say for sure whether this was terribly commonly used, especially for attack, but it did exist.
Hiyazutsu: Fire arrows (hiya) would commonly be shot from bows. Once again, from what I can tell, Japanese military did not use ranged explosives (though they would eventually incorporate cannon into their naval warfare)
Seiryuuto: Totally a real thing! Sort of. The Blue Dragon Sword is indeed a scimitar, but it's from Chinese martial arts, and is only known to Japan through stories and possibly limited use. It might be more accurate to describe it as a falchion of sorts.
Suikan: The word certainly means "blow tube". If anyone used it, though, it would be ninja, not samurai.

[Traab]

Thanks!

I should prolly start posting a list of weapons eventually. I also need to find a name for a dagger hidden inside a jutte because apparently they were made but i cant find an official name for them

Isnt that the weapon the bald dude used in kill bill? When she was wiping out an entire yakuza gang single handed, the bald boss of the gang had some sort of stick weapon that he pulled apart into two blades.

[Bhu]

Isnt that the weapon the bald dude used in kill bill? When she was wiping out an entire yakuza gang single handed, the bald boss of the gang had some sort of stick weapon that he pulled apart into two blades.

Nope. Jutte is a one handed iron truncheon with a prong.

[H Birchgrove]

But that won't insult the enemy! :smalltongue:

It's better known as the dao or sabre. It's a wide, single edged blade compared to the much thinner double edged jian or sword.
Crouching Tiger Hidden Dragon (http://www.youtube.com/watch?v=zY7Kg6BlNec) has an excellent scene comparing the two weapons (it's the first blade that Michelle Yeoh's character uses).


Hi-ya-zutsu: Bamboo tube used to shoot fireworks of flaming arrows.

This sounds very much like the Chinese Bee's Nest (http://www.chinahistoryforum.com/index.php?/topic/32533-the-ming-dynasty-rocket-arrows/).

From some digging, the Japanese would have most likely encountered the Korean version of these weapons (the hwacha (http://en.wikipedia.org/wiki/Hwacha) or rocket cart) during the Imjin wars (http://en.wikipedia.org/wiki/Imjin_War), so it's quite feasible that they captured or developed their own versions in limited numbers.

Most of these weapons sound like they would be used more by ninja and siege engineers though, rather than ashigaru and samurai.

[Bhu]

I'll be doing ninjas after the samurais so i thought Id get their weapons too in advance

[Bhu]

I planned on posting a full weapons list but the BG Forums are down and I didnt copy notes :(

Soon as they pop up will fix that

[Flame of Anor]

Google, yo.

But what firearm does "google-yo" refer to? :smalltongue:

[Bhu]

ok heres a rough draft of the list im considering:


Arrows
Hina-Ya Fire arrow.
Kaburi-Ya/Hiki-Ya/Hiniki-Ya Blunt arrow designed to make whistling sound for signaling.
Karimata V shaped arrowhead.
Mato-ya Blunt arrows for practice.
Togari-Ya Traditional arrow.
Watakusi Large arrowhead with backward facing barbs.
Yanagi-Ba Also called Willow Leaf, a broad arrowhead with a pattern cut into it.

Axes
Fuetsu The Fuetsu was rarely used as a weapon by anyone other than Sohei, but would use Battleaxe stats.
Masakari The Masakari is rather like a hatchet with a backwards facing spike. Again, used more as a tool than a weapon.
Ono The Ono is a Bo staff length axe that could use Greataxe stats. It was probably used as a tool or means of destroying fortifications more often than as a weapon.

Bows and Crossbows
Dai-Kyu/Oyumi The 2 meter tall longbow.
Dokyu Repeating crossbow imported from China.
Hankyu/Koyumi Hankyu refers to the smaller bows used in Zen archery.
Hoko-yumi Mongolian or Chinese recurved bow encountered early. Would have been somewhat rare.
Ishiyumi These would be large wall mounted crossbows, Chinese imports which were used in castle defense (and sometimes used for shooting stones, or multiple bolts). The name also refers to catapults.
Teppo Yumi This would probably be the equivalent of a Hand Crossbow.
Shinobi Yumi I'm using this to refer to short bows it was claimed were used by ninjas because I can't find another name.
Suzume Yumi Hunting bow.

Chain and Rope Weapons
Chidorigane Bizarre weapon consisting of a 46 cm long metal pipe with a tassel at one end, and a short chain with a sharpened metal weight at the end that resembles a Plover's wings. Also called the Nanban. The chain could be retracted or extended.
Chijiriki Also called Chijirigi, or Chigiriki. It's a solid or hollow bamboo or iron staff which hides a length of chain and a large weight. Sort of a hidden flail. Length varied from the users forearm, to that of a Bo Staff. Butt is often shod with metal for striking.

Hananejibo Also called Hananeji or Hananejiri. 30-85 cm staff with a hole 1 or 2 hands lengths from one end through which a cord was wound. Originally a stable tool.
Hayatejo Consisted of 5 iron plates 2-3 cm long connected to each other on the longer side with a hinge, sort of resembling a large bracelet with teeth on the inside of each plate. The two outer plates had rings so they could be held by the thumb and forefinger, with a length of cord attached to one of the rings. Used for restraining prisoners by the hand or throat.
Kaginawa Steel hook attached to a rope.
Kakushi Kusarigama Smaller version of the Kusarigama meant to be concealable in ones pocket. The blade is generally blunt but could be sharpened.

Kururi One of various japanese names for flails, probably wooden.
Kusaribo Also called Kusari Furizue, Kusari Furijo, and several other names. Basically the same as the Chijiriki, but some Chijiriki had spearheads attached to their chain instead of metal weights so I'm using this name for it.
Kusari-Fundo Also called Manriki, Manrikigusari, Ryofundogusari, and God alone knows how many other names. Basically a 12-48 inch chain with a metal weight at each end.
Kusarigama Kama attached to a chain with a metal weight at the other end. There is a variant called the Bauhatsugama where the metal weight is replaced with a fragile container of blinding powder, or poisons.
Kusarijutte Jutte attached to a 6 foot chain with a metal weight at the other end.
Kusariryuta 13 foot chain with a metal weight at one end and a 3 pronged hook at the other.
Kusariuchibo Iron truncheon connected to a chain with a metal weight at the other end. If the truncheon is wood it's called a Bunbunbai.

Mijin Sort of a chain bolas.
Mukujutte/Nanban Hananeji Hananejibo with weight and chain attached that can be extended from one end.

Isn't a "small throwing sword" a "throwing knife"? Sounds like it ought to be, anyway!

[Amiel]

The Japanese refer to their guns as gun-chan.


Apparently, it's also juu 銃/じゅう.

ピストル (pisutoru)
