在日本，男装行业已经面临反复的价格竞争。然而，价格竞争似乎也达到了极限。消费者正在寻找新的附加值，通过新的定制系统适合身体的衣服可能是一个解决方案。一个有效的量身定制系统需要一个合适的体型分类系统。然而，在日本很少进行男性尸体的分析。最终目的是对日本男性的体型进行分类，并使用三维身体扫描数据创建一个新的量身定制系统。在这项研究中，我们的目的是澄清的因素，占日本男性的身体形状之间的多样性，并制定一个分类系统，日本男性的身体形状。从20 ~ 79岁的429名男性中随机抽取20、30、40、50岁各年龄组男性50名，60、70岁各年龄组男性50名，共计250名男性。身体线条扫描仪被用来测量每个人的身体。在这项研究中，躯干，这是限制在臂孔内，领口以下，转子点以上，进行了分析。根据标志统一原点：颈后点为X轴（横向）原点，转子点为Y轴（垂直方向）原点，右侧颈点为Z轴（矢状方向）原点。为了进行统计分析，每个个体的数据通过HBM软件转换为同源模型。采用DHRC-HBS人体形态统计软件对同源模型进行主成分分析。提取了七个因素，并解释如下。第一主成分（PC 1）为树干高度因子。PC 2是躯干在腰围以上向前或向后倾斜。PC 3是躯干的厚度。PC 4和PC 5为左/右差异。PC6是向前或向后肩。PC 7被认为是肩部相对于下躯干的扭曲。PC 1、PC 2、PC 3和PC6的主成分得分用于统计软件IBM SPSS Statistics的聚类分析。分析结果为7个聚类。CL 1和CL 4与250名受试者的平均形状相似，尽管CL 4比CL 1高。在30多岁、40多岁和50多岁的男性群体中，CL 1和CL 4占男性的50%。CL 6比CL 1更细长，在CL 6中，身体躯干较薄，并出现后摇，其频率在20多岁的男性中相对较高。CL 7代表良好的姿势，胸部发达。CL 3有一个圆形的背部和前肩，这些人都很矮; CL 3包括50%或更多的60多岁和70多岁的男性。CL 2是向后弯曲，腹部突出，这被认为是所谓的代谢型，在50多岁的男性中占20%。这种人体分类系统被认为是适用于虚拟服装假人设计和定制系统。
In Japan, the men's clothing industry has faced repeated price competition. However, it seems that price competition is also reaching its limit. Consumers are looking for new added value, and clothes that fit the body by a new made-to-measure system could be one solution. An appropriate classification system of body types is needed for an efficient made-to-measure system. However, analysis of male bodies has rarely been performed in Japan. The final purposes are to classify the body types among Japanese men, and create a new made-to-measure system using three-dimensional body scanning data. In this study, our aims were to clarify factors that account for the diversity among Japanese men’s body shapes, and to develop a classification system for Japanese men’s body shapes. The data of 50 men in each age group of men in their 20s, 30s, 40s, and 50s and 50 men in their 60s and 70s, totaling 250 men, were randomly selected from 429 men aged 20 to 79 years old. A body line scanner was used to measure each person’s body. In this study, the trunk, which was restricted to the inside of the arm hole, below the neckline, and above the trochanter point, was analyzed. The origin was unified based on the landmarks: the back-neck point was the origin of the X-axis (transverse direction), the trochanter point was the origin of the Y-axis (vertical direction) and the right-side neck point was the origin of the Z-axis (sagittal direction). To enable statistical analysis, the data from each individual were transformed to a homologous model by HBM software. The homologous models were analyzed by principal component analysis with DHRC-HBS Human Body Shape Statistics software. Seven factors were extracted and interpreted as follows. The first principal component (PC1) was the factor of height of the trunk. PC2 was inclination of the torso forward or backward above the waistline. PC3 was thickness of the torso. PC4 and PC5 were left / right difference. PC6 was forward or backward shoulder. PC7 was considered as distortion of the shoulder relative to the lower trunk. The principal component scores for PC1, PC2, PC3, and PC6 were used in cluster analysis with the statistics software IBM SPSS Statistics. The analysis resulted in seven clusters. CL1 and CL4 were similar to the average shape of the 250 subjects, although CL4 was taller than CL1. CL1 and CL4 accounted for 50% of the men in the groups of men in their 30s, 40s, and 50s. CL6 was slenderer than CL1; in CL6, the body trunk was thin and showed swayback, and its frequency was relatively high among men in their 20s. CL7 represented good posture with a developed chest. CL3 had a round back and front shoulder and these men were short; CL3 comprised 50% or more of the men in their 60s and 70s. CL2 was bending backward with a protruded stomach, which is considered to be the so-called metabolism type, and comprised 20% of men in their 50s. This body classification system is considered to be applicable for virtual dress dummy design and for a made-to-measure system.
