Familiar has always prioritized "quality" over "efficiency." This spirit of craftsmanship is particularly evident in the production line known as the "K Line." The "K Line" is Familiar's original production line, primarily producing one-piece dresses and gowns. When the company was first founded, products were made between the homes of Atsuko Sakano and Mitsuko Tamura, but once the business got on track, most of the work was done at Mitsuko's home, and the "Okamoto Laboratory" was later built on Mitsuko's property. The "K Line" was named after the initials of this laboratory. Work such as embroidery was done at home, and the products were delivered to the laboratory.

The four women who founded Familia used their meticulous embroidery and handicraft skills to sew dresses. The "K Line" is a collective name for products that retain that enthusiasm and texture, and is, so to speak, the origin of Familia. Mitsuko Tamura, who worked at the "K Line," was in charge of production and quality control. Mitsuko said, "Clothes reflect the heart of the person who sews. People with a relaxed attitude will wear relaxed clothes, people with a soft personality will wear clothes that are somehow fluffy, and people who are competitive will wear clothes that are crisp and tight." The K Line slowly and carefully created clothes perfect for special occasions with meticulous skill and consideration. The spirit of the "K Line" is still handed down to Familia's products today.

When the company was first founded, Tamura Etsuko created most of the designs for Familiar's products. When designing, Etsuko was careful to express the correct form of the object without adding her own desires. She believed that in the fashion industry, you cannot capture people's hearts by simply imitating others. To that end, she would go to the zoo to check the position of the eyes, their size, and so on. Her passion is still carried on today.

We also pay particular attention to the motifs on our clothes, such as embroidered patches and printed patterns. We hope that these motifs will help children develop a love for nature, such as flowers, clouds, mountains, trees, and animals. For example, before a performance, a nervous child might see the bear's face encouraging them, saying, "Do your best!" Or, when a child is scolded and looks down, the embroidered dog on their pants might comfort them, saying, "It's okay! Be a good boy!" We always strive to use shapes, expressions, and colors that will inspire children in this way.

We are particular about creating a three-dimensional design that adapts to a child's growth and patterns that do not restrict movement, taking into account their physical activity. Each child grows in different areas and at different times. Sleeping, crawling, touching, walking, kindergarten, early elementary school, and upper elementary school. The balance of each part of the body differs at each age. Therefore, whether it's a traditional style or a trendy design, comfort is only possible if the pattern is suited to the child's growth.

Familiar has two main goals when it comes to color selection. The first is to ensure that colors are easy to coordinate with previous seasons' clothes. While children often cannot wear the same size for years, we strive to ensure that children can wear their clothes for as long as possible, so that they can wear last year's sweatshirt with this year's pants without feeling out of place. The second goal is to consider children's emotional development. Children grow up encountering many different people and things, experiencing a variety of emotions and excitement. The ability to effectively bring out individuality is cultivated from an early age, and color coordination plays an important role in this. It is also widely known that colors have a psychological impact, so we take care to avoid choosing colors that have a negative impact on children's emotions.
