General principles of Mitogaku exist in the next phrases.
1. Loyalty and filial piety is peerless.
2. No distriction between pen and sword,
3. Reverence and respect confusianisum.
4. Scholarly persuits make efficacy as others.
I will state above mentioned phrase No.2 expressly.
1) No distriction between pen and sword.
What is the “no distriction between pen and sword.” Pen without sword is not signify the pen, sword without pen is not signify the sword.
Anybody be materialized of these, main mankind is follows.
Mr. Mitsukuni Mito-Feudal clan's lord.
Mr. Nariaki Tokugawa-Feudal clan's lord. Mr. Toko Fujita-The scholar is splended one.
By Mr. Nariaki's Tokugawa order, Kodokanjutsugi (the greatest book) is compiled.
Mitogaku's whole soul into this book is thrown since then Mr. Mitsukuni Mito consistently.
The main discourse is into discuss throughly concerning above No.2 subject.1) I will participate in the modern significance lastly an end.

Mune-yoshi Yagiyu got acquainted with Hide-tsuna Kami-izumi in 1563 (A. D.). At that time, Mune-yoshi was thirty-five years old and he was commonly acknowledged that he was one of the greatest swordsmen ever known. But, realizing that Hide-tsuna's talents was supreme far ever, he hoped to become a pupil of Hide-tsuna, and he studied under Hide-tsuna.
Later, Mune-yoshi was qualified for the teacher of Kage-Style by Hide-tsuna.
I have some questions as follows, what style he had learned before.
I suppose as follows.
Yagiyu-shin-kage-ryu-engi which was transmitted to the Yagiyu family in 0-wari district was suggested him to belong Shin-to Style, and the annals of the Yagiyu family in Edo district was suggested him to belong Toda Style.
Shin- kage Style is said that was added to new idea to Kage Style that was created by Iko-sai Aisu. I think that it had not a simple progress, but especially Yagiyushin-kage Style was performed a merit of Shin-to Style, Toda Style and various styles. Then I would like to know and study more about those relation by the comparison the literature on this subject.

In order to detect cases of Exertional Hemoglobinuria among Japanese Martial Art trainees, urine specimens obtained from 114 student members of Martial Art clubs (Kendo, Judo, Karate and Aikido) were examined.
Exertional Hemoglobinuria was found in 15 out of 60 Kendo trainees and 3 out of 16 Aikido trainees respectively.
Among these 18 cases of hemoglobinuria, however, only 3 cases presented macroskopic hematuria and the remaining 15 showed normal coloured urine.
Thus, it must be emphasized that in Japan Martial Art training, especially Kendo exersise, is one of the main precipitating factors of Exertional Hemoglobinuria, and that there are often latent forms of the disease in which gross hematuria is not present.
In considering the hemolytic mechanism occurring in Kendo exercise, I assume that the special action called “Fumikomi” operates as a mechanical trauma on the soles of the feet, although there must be other unknown factors for the development of this condition.

on, showing rather a tendency of backward inclination. In case of the For the purpose of disclosing the morphological feature of top class judo champions, analyses of their standing postures were made with the conformateur as a part of the study to elucidate the physical aptitude for judo. The investigation of standing postures was made by taking photographs of lateral aspect applying the conformateur (Fig.1), and measurements of several angles such as shown in Fig.2 concerning the curves of the vertebral column. Measurements were made in cases of three kinds of standing postures, viz., usual standing posture, strained standing posture and standing posture with the forward bent head. The subjects were 24 men who joined the training camp of June,1975 and 25 men who joined the training camp of May,1977 and all of them were top class judo champions of this country.
In case of the usual standing posture, the forward inclination of the upper part of the body as well as the whole body was generally smaller in judo men than the ordinary men, and there was noted a tendency, the lighter the body weight, the smaller the inclinati strained standing posture, the individual variations were generally small, and no difference in the mean value was found among body weight classes. Regarding the curves of the vertebral column, judo men showed rather larger anteriorly directed curves in the lumbar area, but the columns were rather erected in the cervical as well as thoracic area. Accordingly, the center of gravity was usually low in them. Even if the posteriorly directed curves in the thoracic area was stressed by bending forward the head, the above-mentioned tendency was not changed, and there was noted no difference among the body weight classes, although individual differences were noticeable (Table 1,2 and 3). On the basis of above-mentioned findings, it was presumed that the activity of the trunk muscles resisting against the gravity in order to keep the erect standing posture is a little more vigorous in judo men than in the ordinary men in case of usual standing posture.
In short, it was considered that there is acting a contractive tension of the deep back muscles in the cervical, thoracic, lumbar and sacral area in keeping the standing posture. However, the results of analyses of the postures of judo men seem to suggest that differences in the intensity of the contractive tension are not attributable to the degree of training and the body weight, but they are merely individual differences.

International Judo Federation initiated the World Woman's Judo Championship Competition in the near furture, according to the same rule as men's judo.
The study was to investigate physical fitness of Japanese Woman's Judo player in terms of maximum aerobic capacity and to compare the black belt group with white belt group and that of another top athlete group.
19 subjects were tested, including one foreign player. Maximum oxygen uptake was determined by the progressive loading method with Monark's bicycle ergometer. The pedal frequency was 60 rpm until the exhaustion. Gas was collected with Douglas bag and analyzed by Scholander technique. Maximum heart rates were determined from ECG method. Body density was computed with Nagamine and Suzuki's formula, and then, it was inserted into the Brozek's formula to produce the total body fat.
Maximum oxygen uptake averaged 2.09 1/min. in white belt group and 2.42 1/min. in black belt group. And then, black belt group showed higher values in Vo₂max. /weight, Vo₂max. /L. B. M., vital capacity and V_Emax.. But, Rohrer's index and total body fat(%) showed higher values in white belt group. However, maximum aerobic capacity level of Japanese Woman's Judo players was lower than the top athlete group.

Ukemi has great weight with judo. It is an effective technique of keeping ourselves safe when we are hurled, it is indispensable for protecting us from pain or injury.
This research deals with “the effacement of the impact by the use of the arm”which is one of the theories of ukemi.
We have examined the effect on diminishing the impact by giving a tatami a sharp touch in comparison with the case of not using the arm.
We have made experiments on each kind of nagewaza to see the impact, the order in which each part (the flat of the hand, the middle joint of the arm, the shoulder, and the hip) keeps in touch with a tatami and the intervals among them.
This is the outcome of scientific research:
(I) Concerning the effacement of the impact by the use of ukemi; the effect of ukemi is apparent to us judging from the maximum and impulse per second of ipponseoinage when it is the time for doing ukemi or not doing it.
(II) We get the impulse of each nagewaza lined up in an order based on how large they are; (1) ipponseoinage (2) osotogari (3) haraigoshi and (4) sasaetsurikomiashi.
(III) Concerning the impulse per second; (1) haraigoshi (2) ipponseoinage (3)sasaetsurikomiashi and (4) osotogari. Concerning three parts. (1) the part of hip (2) the part of back and (3) the part of arm.
(IV) Concerning the time when ukemi is finished; ipponseoinage (0.204 sec.), osotogari (0.260 sec.), haraigoshi (0.191 sec.), sasaetsurikomiashi (0.174 sec.) and ouchigari (0.126 sec.).
