You may have come across the brand “Yamisan” while looking for smartphones or portable chargers.
While the name might lead many to imagine a Japanese company, which country is the brand actually from?
In this article, we will investigate the true nature of Yamisan based on trademark registrations and seller information, and provide a detailed explanation of its history, product characteristics, and reliability.
What you will learn in this article!
Which country is Yamisan from?
First, let’s confirm the country of origin for the Yamisan brand.
Based on publicly available trademark information and seller data, we can summarize the following points:
- In Japan, the trademark was registered in 2022 by a Chinese national named “Duan Shan.”
- In the European Union (EU), it was registered in 2023 under the name “Shan Deng (China).”
- The official website does not list a company name or physical address, focusing instead on the brand’s design philosophy.
- The sellers on Amazon are all companies based in Changsha, Hunan Province, China.
In short, Yamisan is a brand originating from China, distributed in the Japanese market through import sales.
Ms.gadgetI thought it was a Japanese company, but it’s a Chinese brand?
Mr.gadgetThat’s correct. The trademark is registered under a Chinese name, and it is sold in Japan via import.
The history of Yamisan
The history of Yamisan is still brief.
By following the timeline of trademark applications and registrations, we can see its progress.
- December 8, 2021 (Japan): Filed for the “Yamisan” trademark (Class 9).
- June 24, 2022 (Japan): “Yamisan” trademark registered; rights holder is Duan Shan (individual).
- 2022–2023 (Japan): The same rights holder registered “Lovaree” (Class 9) and “Alybes” (Class 11).
- August 1, 2023 (EU): “Yamisan” registered in the EU under the name Shan Deng (Class 11).
As shown, trademarks have been registered in Japan and the EU one after another since 2021, indicating that the brand is expanding multiple lines in a short period.
Ms.gadgetSo it’s a relatively new brand.
Mr.gadgetYes. Since it was registered in Japan in 2022, it is an emerging brand that has only been around for a few years.
Features of Yamisan products
Next, let’s organize the features of Yamisan products.
Based on items currently sold on Amazon and descriptions on their official website, the following points can be noted:
- Main products: MagSafe-compatible portable chargers (10,000mAh class, PD/QC support), wireless chargers, etc.
- Design trends: Focused on the Apple ecosystem, emphasizing thin, lightweight, and titanium-style designs.
- Safety: Includes specifications regarding safety, such as PSE compliance and the inclusion of temperature control chips.
- Utility: Can be used not only for charging smartphones on the go but also as an emergency power source during disasters or power outages.
However, consumers should be aware that sales are primarily conducted through the Amazon Marketplace and that the transparency of official information is not sufficient.
Ms.gadgetIsn’t it a bit concerning to buy something if there’s little brand information available?
Mr.gadgetIndeed. Since official company information and support structures are unclear, it is safer to carefully check reviews and sales history before making a purchase.
Summary
Let’s summarize what we have covered so far.
- Which country?: A brand from China, with trademarks registered in Japan and the EU.
- History: Applied in Japan in 2021, registered in 2022, and registered in the EU in 2023.
- Features: Primarily focuses on MagSafe-compatible portable chargers. While it emphasizes design and practicality, there are challenges regarding transparency.
Yamisan is a relatively new brand from China, and its product design and functionality have received some positive feedback.
However, because official company information and support systems are limited, it is important for users to thoroughly verify information before purchasing.
Ms.gadgetSo, is it reliable? Or should I avoid it?
Mr.gadgetI cannot say for certain. However, given the lack of official information, a neutral perspective would be to treat it as a “brand to be considered with caution.”
