When advertising in Japan, don’t worry about the website, worry about gooogle
Japanese has a non-latin based writing system which is unique, even though there are borrowed elements within. This did not pose a problem originally but this changed with the computer age.
Most websites use a Latin based Web address to search (exploringlanguages.org is a brilliant example) rather than a Arabic, Japanese, cyralic or other root based language. One reason for this is the adaptability the Latin based system, as it can spell out the phonics of other language systems.
This has effected Japanese in a particular way. While English language learning is heavily emphasised at schools here, not everyone understands the need; either globally or within Japan. This has left many people without the ability to read non-Japanese scripts–which brings us back google.
As any polygot knows, you can Google in other languages, without exception. Therefore what often happens in Japan is that advertisers don’t include their website address (due to the Latin based system ) but they instead include the information one is to Google to get to the website.
While it is a strange system, its the Japanese way and not likely to change any time soon.
Thank you for reading and happy exploring.
