Trademark Opposition: Samurai vs Samouraï

In a trademark opposition disputing the similarity between “Samurai” and “Samouraï”, the Japan Patent Office (JPO) dismissed the opposition filed by Parfums Samouraï SA against TM Reg no. 6384904 for a stylized word “Samurai” due to dissimilar to “Samouraï”.

TM Reg no. 6384904 “Samurai”

The opposed mark, consisting of a stylized word n “Samurai” (see below), was applied with the JPO on September 29, 2020, for use on cosmetics, soaps, perfumes, fragrances, and other goods in class 3 by a Japanese business entity, Yugen Kaisha Life Products.

The JPO granted protection on February 12, 2021, and published for opposition on May 25, 2021.

Apparently, the applicant promotes soaps in the name of “SAMURAI SOAP” via the internet.

Opposition by Parfums Samouraï SA

Opponent, Parfums Samouraï SA, alleged the opposed mark shall be canceled in contravention of Article 4(1)(x) and (xi) of the Japan Trademark Law by citing earlier trademark registrations for the wordmark “Samouraï” in classes 3.

The opponent argued that they have been promoting perfumes and fragrances, hair wax, and softener bearing the “Samouraï” mark since 1997, and thus the opponent mark has acquired a certain degree of reputation in the industry of perfumes. Besides, the opposed mark has the same sound and meaning as the opponent mark, namely, a member of a powerful class of fighters in Japan’. If so, both marks shall be deemed similar even though there is a difference in appearance.

JPO decision

To my surprise, the JPO Opposition Board found that it is doubtful if the opposed mark consists of the term “Samurai” from appearance. The initial letter is true “S”. But subsequent letters are illegible. If so, the opposed mark would not give rise to any specific sound and meaning.

Given the opposed mark does not have a sound and meaning relating to “Samurai”, the Board can’t find a reasonable ground to believe a certain degree of similarity between the opposed mark and the opponent mark.

Based on the foregoing, the JPO found the opposed mark shall not be canceled in contravention of Article 4(1)(x) and (xi) and dismissed the opposition entirely.

Trademark dispute over Shogun Emblem of the Samurai Era

In a recent appeal trial over trademark dispute, the Trademark Appeal Board within the Japan Patent Office (JPO) overturned the Examiner’s determination and held that a combination mark with Tokugawa crest image and literal elements written in Chinese characters is dissimilar to, and unlikely to cause confusion with a senior trademark registration for the “TOKUGAWA CREST” device mark in connection with pickled plums of class 29.
[Appeal case no. 2018-6893, Gazette issue date: March 29, 2019]



The Tokugawa clan was the family that established the Edo shogunate, also known as the Tokugawa shogunate, (1603–1867), the final period of traditional Japan, a time of internal peace, political stability, and economic growth under the shogunate (military dictatorship) founded by Tokugawa Ieyasu. The Tokugawa shogunate continued to rule Japan for a remarkable 250 years and ended in 1868, with the Meiji Restoration when the Emperor regained power.

The Tokugawa crest was a circle in closing three leaves of the awoi (a species of mallow, found in Central Japan) joined at the tips, the stalks touching the circle (see below).

This gilded trefoil is gleaming on the property of the shogun and mausoleum even now in Japan.



Kabushiki Kaisha Kiwa-Nouen Products, a Japanese merchant dealing with plums and its products filed a trademark application for a combination mark with Tokugawa crest image and literal elements written in Chinese characters (see below) covering pickled plums in class 29 on June 21, 2016 [TM application no. 2016-72127].

Three Chinese characters “紀州梅” in the upper right of the mark lacks distinctive since the term means plums made in Kishu, the name of a province in feudal Japan (the area corresponds to nowadays Wakayama Prefecture and southern Mie Prefecture), as a whole. Two characters “夢葵” in the center of the mark to be pronounces as “yume-awoi” is obviously a coined word and distinctive in relation to pickled plums.

The mark is actually in use on high-class pickled plums produced by applicant.

Tokugawa Museum

Going through substantive examination by the JPO examiner, applied mark was totally refused registration based on Article 4(1)(vi), (vii), (xv) of the Trademark Law on the ground that the mark contains a device resembling the Tokugawa crest which becomes famous as a source indicator of ‘Public Interest Incorporated Foundation The Tokugawa Museum’.
If so, using the mark on the designated goods by an unauthorized entity may free-ride goodwill vested in the Tokugawa crest and anything but conductive to the public interest. Besides, relevant consumers are likely to confuse or misconceive pickled plums using applied mark with goods from The Tokugawa Museum or any business entity systematically or economically connected with the museum.

Article 4(1)(vi) is a provision to refuse any mark which is identical with, or similar to, a famous mark indicating the State, a local government, an agency thereof, a non-profit organization undertaking a business for public interest, or a non-profit enterprise undertaking a business for public interest.

Article 4(1)(vii) of the Trademark Law prohibits any mark likely to cause damage to public order or morality from registration.

Article 4(1)(xv) provides that a mark shall not be registered where it is likely to cause confusion with other business entity’s well-known goods or services, to the benefit of brand owner and users’ benefits.


Applicant filed an appeal against the refusal on May 21, 2018 and argued dissimilarity of the marks.


Appeal Board decision

The Board reversed the examiner’s refusal and admitted applied mark to registration by stating that:

It becomes trade practice to print family crest on the packaging of food products. Especially, trefoil awoi crest has been commonly used on the packaging of specialty products or souvenir from Aichi (Owari), Wakayama (Kishu) and Ibaragi (Mito) Prefectures where descendants from clan founder Tokugawa Ieyasu’s three youngest sons governed during the Edo shogunate. Besides, from appearance, Tokugawa crest image in applied mark looks like a background pattern and thus relevant consumers are unlikely to aware that the pattern serves the legally defined role of a trademark because the image is colored washier than literal elements. If so, two Chinese characters “夢葵” of the mark functions primarily as a source indicator.

Based on the foregoing, the Board considered, given the Tokugawa crest image in the applied mark does not play a role of source indicator at all, both marks are dissimilar and unlikely to cause confusion from visual, phonetic and conceptual points of view even if the Tokugawa crest becomes famous as a source indicator of Public Interest Incorporated Foundation The Tokugawa Museum in fact. Likewise, the Board found no specific reason to cause damage to public order or morality from applied mark.
