Based on a japanese children's book by Yoshie Kawaura. Shiba-wanko, a Shiba-inu dog, and Miike-nyanko, a calico cat, live together in a classic Japanese-style house with the traditional Japanese alcove called a tokonoma. Shiba-wanko is a very gentle and hardworking soul who does all of the cleaning, laundry and cooking in the house. Miike-nyanko is a different type all together, being rather temperamental and not very good with housework. Together, these two learn the manners and customs associated with events such as the proper Japanese way to treat one's guests, preparing for a Japanese New Year and how to enjoy the kimono, the traditional Japanese costume. Each chapter covers a specific topic which has to do with living in "Wa" (the Japanese-style spirit of peace and harmony) throughout the changing seasons.

故事的主人公是生活在一起的温柔勤劳的柴犬阿旺和调皮可爱的三毛猫阿妙（都是女孩）。她们一同生活在一间和式的平房里。绘本采用了温暖明亮的色调以及细腻自然的水彩画风描绘了生活中的种种趣事。它的一大特色就是对日本和式风俗和日本文化传统的细致描绘，几乎可以作为一本日本民俗风情的教材来使用。
