ok this is a long one i put the comments under each weapon.
Aikuchi
A weapon of preferable for women, it can be concealed very easily in ones clothes, kimono or sleeve. Very useful to make sneak attacks with or to strike at a very unsuspecting moment. it is shorter than an tanto and lacks a Tsuba (hand-protector).
Damage: 4 to 10 + Strength Modifier
Requirements: 5 ranks of sword
Modifier: Agility
Blacksmith DC: 30
Aikuchi are straight bladed and any sword or knife can have a Tsuba. But the tsuba costs and ninjas were dirt poor. so buying a really nice tanto with a tsuba and proper handle would be really hard for them. And the aikuchi at the longest was 1 shaku and shortest about 5 cm. the aikuchi usually stayed below half a shaku.
Bokken
A wooden replica of a sword, also known as a bokuto (wooden sword). It is very widely used as a training weapon, and sometimes by people who do not want to kill their opponent. Mostly made of traditional oak wood and made of the same weight as a real sword to give it the same momentum.

well if you are doing training weapons there is a hierarchy. (lowest to highest) shinai, bokken, sakabato, real weapon. The shinai is what low ranks students learn with until a point in their training then they get the bokken. Bokken actually were made out of one of two materials white oak or wax wood. The sakabato is a unique training weapon in that is closest to the real sword being made in the same way the real sword is made, except that the razor side is on the opposite side than normal. And the other thing about the sakabato, being almost exactly like a normal weapon and special for training, they actually cost more than a real blade. And I forgot to say that that the shinai are made from bamboo.
Dao
The Dao is a single edge sword much like a saber or scimitar. These sword are relatively light and fast. Some ninja also use a dual pair of these swords to confuse an enemy. They are truly one sword split in two. The user of the Dao are agile and strong.

Dao are not fast they are average at best. But they have a neat handle blade build. This build gives the dao an easily interchangeable position. It is not speed that gives it advantage maneuverability. It is like you gain a 100 yd lead on a beach assault then when enemy tries to push you back you sorry I have trenches and dog in then continue with the assault. And a dual dao were not one sword at any point they were always two blades with fitting tsuba and larger shi-su to compensate for having two blades in it.
Katana
The Katana is the most well-known sword and one of the strongest. It is generally a two handed sword, but strong shinobi who have trained with it are able to wield it easily with one. The blade has one edge that is sharp and can cut through almost anything.
Damage: 8 to 15 + Strength Modifier
Requirements: 20 ranks of Sword, Strength 25
Modifier: Strength
Blacksmith DC: 40
When you say katana I assume you mean the modern day sler for a tachi/daito. The tachi/daito is a sword with a 3 shaku blade. The even curve that archs to the dull side creates an idea smooth cut or slash. And the katana class size has another blade type. Like the ninjato in the sence it has no arch to its back, the tsurugi. The tsurugi is a straight single edge blade three shaku long
Ninja To
Upon reaching Jounin rank, every shinobi is introduced to this weapon since it is the favored weapon of the Anbu. It is lighter than the Katana, so it is easier to wield with one hand. However, it is much stronger than the Dao. The Ninja to is also shorter than the katana in length, but same in width and has a straight edge. therefore cutting like with a katana becomes useless and this decreases the fluency with which the weapon can be wielded.

When you say “However, it is much stronger than the Dao.” I hope you do not mean in durability because it you had a machine that stroke a ninjato and a dao against each other the ninjato would break every time for a million and two reasons. ok that may be an exaduaration but the dao is better tempered, thicker, broader, heavier, and so on and so on. You may want to mention that a ninjato has a two shaku straight single edge blade. The other blade in the wakizashi class it the shoto this blade in more like what you call a “katana” but at the length of the shoto is 2 shaku like the ninjato.
Nodachi
Sometimes bigger is better, the Nodachi is even larger then a Katana. There are several synonyms for it, like Odachi, Daikatana and Zanbato. Equalling 3 shaku at least, the sword can sometimes even become 6 or more shaku (2 meters).

I reemed this one a new butt hole already.
Tanto
The japanese knife, or tanto, is normally 1 shaku (1 foot) in length. It can be thrown short distances and used as a close quarter weapon.
Damage: 5 to 10 + Strength Modifier
Requirements: 10 ranks of sword, Aglity 15
Modifier: Agility
Blacksmith DC: 25
The tanto it basicly the opposite of an aikuchi, the tanto was about 1 shaku but dropped to about about 5 cm at the shortest. The tanto was typically above the 1 half shaku.
Jo
The light weight training weapon for those interested in the staff family to train with. The Jo is small and made of the lightest of woods for easily handling. The Jo is there to teach technique and stance, not for damage dealing.
Damage: 1 to 6 + Strength Mod
Requirements: N/A
Modifier: Endurance
The jo staff is a full function weapon. What I mean by that is that it is used in practice and in combat. So I should say it is a combat ready weapon. And you can tell my sore spots the next tell I get drag into a melee fight against a person with a hanbo, jo, or bo ok. Hanbo is 3 shaku, jo is 4-5 shaku, and bo are 6-7 shaku
Naginata
A long pole with a blade on the end, accompanied by a Tsuba (Hand Protector). A very useful weapon to keep enemies at a distance and to make swift movements if you're skilled with it. As long as you make successful hits with this weapon, the target can move move in close enough to use Taijutsu.

I do not know you have a normal oriental halberd like this one.
http://i235.photobucket.com/albums/ee207/duodrake/halberd.jpg and the big heavy one in the staff stuff.
Spear
The spear can be crafted in many different ways. The pole can be made out of bamboo to provide with a flexible middle-ranged attack. It can also be made with metal to ensure a strong piercing weapon. The users of the spear are able to keep enemies from getting close to them by keeping the tip of the spear in their way. For every successful attack with the spear, the opponent can not get close enough to use melee or taijutsu.

If we are calling things in there Japanese name why not call it “kamayari
Staff
A staff is basically a rod made out of any material such as wood, iron or silver. Its a plain weapon with no blades, but quite handy. Most ninja refer to the staff as a 'bo', however it can sometimes get confused with the ranged weapon, 'bow'. For the roleplay sake we will refer to it as a staff.
Damage: 3 to 8 + Strength Modifier
Requirements: 5 ranks of Staff
Modifier: Endurance
Blacksmith DC: 15
You should put in the length it is in the jo staff rant.
Kama
The kama was a weapon favored by a ninja on a mission who could disguise himself as a farmer work all day as one and then kill during the night with the kama he used to cut the grass on his farm. The blade is thin and weak, so not desirable for most combat situations.
Damage: 4 to 7 + Strength Modifier
Requirements: 5 ranks of Melee
Modifier: Strength
Blacksmith DC: 15
Wrong the kama is a unique weapon. The kama in not thin or weak it is thick and bridal. And fyi the scythe cut the grass and the sickle or kama was used in the bailing prosess.
Kunai
Everyone knows what a kunai is! It is the shinobi weapon that is quite simple in design with its abstract diamond point, thin handle and loop at the end. The kunai is usually made of steel with white cloth wrapped around the handle to keep the metal from rubbing against a shinobi's hand and for better grip. The Kunai is a melee weapon as well as a throwing weapon. See the 'Throwing' post for more details for throwing a Kunai.
Damage: 5 to 9 + Strength Modifier
Requirements: N/A

Blacksmith DC: 10
WHEE utility field knife. The kunai is still used today as a field knife.
Tekagi
This weapon is worn on the knuckles like a glove. But on this glove are bladed prongs. They can be long or short. Longer blades are easily broken, but can do more damage. Shorter blades are sturdy and do a decent amount of damage. This weapon was made for taijutsu users to add a little extra damage to their punch.
Damage: 7 to 11 + Strength Modifier
Requirements: 10 ranks of Melee, Strength 15
Modifier: Strength
Blacksmith DC: 20
Wrong again. Tekagi was maninly climbing gear and theses “gloves” have little prongs or spikes on the palm of the hand and longer claws protruding from the back of the hand off the knuckles. The claws usually are 1 or ½ shaku. The tekagi is a cousin to the katar. a broad single that goes with the hand instead of the fingers.
Whip
The whip, originally a tool to keep animals in check, but when used as a weapon, it proves very useful in disarming and grappling the opponent. Not to mention it's swiftness and the ability to give attacks burning with pain without physically wounding the enemy much. When using the whip in a grapple, the target must use the skill escape to get out once caught.
Damage: 6 to 10 + Strength Modifier

Very descriptive
Jitte
A small piercing weapon which consists of a long prong with a small curved prong on the side, it's very useful to disarm an opponent and block attacks once you know how to handle it. However, its not used to cause damage. Not a lot of strength is needed if the user is quick and precise with their movements.
Damage: 3 to 8 + Strength Modifier
Requirements: 5 ranks of Ninja

Blacksmith DC: 15
Ouch I would hate to get pieced by a 14 in rod that has no point.
Kusarigama
The kusarigama is the union of a normal kama with a chain on the end of the kama handle. The kusarigama is one of the hardest weapons to master and one of the most useful ones. The Kama can be used to attack in close quarters while the chain which most of the time has a small metal ball like ending can be used for ranged attack, trips and disarming as well as creating vast numbers of opening for the user to kill with the kama sharp edge. The chain can be used to grapple, but target must be within close range.
Damage: 7 to 12 + Strength Modifier

A Tessen is a war fan. It is a fan made of metal. They are mainly used as melee weapons, but are also used for ranged attacks. A skill user of the Tessen can use it like a shuriken. Even higher skilled user can make the Tessen return after throwing it. Those with the Wind affinity can also use this device in ninjutsus. Most ninjas wield two Tessens.

Club

Ok a club the most European/precivilization weapon known to man and we have it as a ninja weapon. I hope there are others who think there is something wrong with this too.
Hammer
A large over-sized hammer usually made with two flat heads. An experience blacksmith could sharpen the edges of the hammer to do more damage by making them come to a point. It takes a lot of strength to lift the hammer and a lot of endurance to constantly throw it about. The hammer is more specifically used to break bones and crack skulls.
Damage: 10 to 15 + Strength
Requirements: 20 ranks of Heavy, Strength 25
Modifier: Endurance
Blacksmith DC: 25
Is this a European two handed hammer? Or a one handed mallet like hammer
War scythe
A pole weapon that was at first improvised from the usual farming scythes. it is made of a large blade attached to a long pole.The blade, unlike that of a Naginata or other lance like weapons is placed horizontally and it is curved inward making it great at slashing and ripping. This weapon found it's origin in the farming sector where it was used to cut rice more efficiently, but when you can harvest rice, why not harvest lives? The weapon was first used in revolts from farmers but later on, their custom creation was begun for war uses where it has proven it's usefulness because of the many victims that have fallen to this weapon. The War scythe is always taller than the user and its blade is usually as long as the user's arm span. It takes quite a bit of strength to swing around a large and heavy weapon like that so both hands are used when swinging. It takes a skilled blacksmith to create a balanced blade and pole. The pole especially has to be strong since it's long and holds up such a powerful blade. Shinobi use of this weapon is scarce for it is more efficiently for intimidation and killing sprees rather than stealth.
Damage: 15 to 21 + Str Mod
Requirements: Strength 35, 40 ranks of Heavy

Well again if we are naming things in Japanese call it daikama
