Nakatani

Amane is an umbrella line featured separately from NaturalBasic and other lines on Nakatani’s official product site. Its products include the lightweight folding umbrella Air＋, the “ぬれないンブレラ,” which has a feature for storing wet umbrellas, and reverse umbrellas. The line emphasizes portability and functionality during use and storage. While NaturalBasic offers products in a wide range of designs, Amane is positioned around functionality and serves a different role from Sheil&Sheil, which has products for children.

On the official product site of Nakatani Co., Ltd., NaturalBasic is used as the name of a standalone product category, grouping several types of umbrellas, including long umbrellas, folding umbrellas, and parasols. It is a staple line with a broad range of products, including plain, two-tone, and patterned designs. On the official product pages, it is organized as a separate category from Amane, which highlights features such as lightweight construction and storage, and Sheil&Sheil, for which products for children can be found. As another company also has a brand with the same name, here it is treated as a name used for Nakatani’s umbrella products.

Sheil&Sheil is an umbrella brand line sold at major retailers under its own distinct name as a Nakatani product. Its offerings include children's folding umbrellas and umbrellas distinguished by their patterns and colors. It is positioned as a product group distinct from NaturalBasic, which covers a general range of umbrellas, and Amane, which emphasizes lightweight construction and storage features. Information also confirms that Nakatani Co., Ltd. holds a trademark for the same name, supporting its treatment as one of Nakatani's umbrella brand family rather than merely a product name or the name of an operating company.
