Google Maps language

I posted the following URL of Google Maps on my forum.
This URL contains code that enables to replace the Japanese language with English in Google Maps.,+Onomichi-shi,+Hiroshima-ken+722-0045,+Japan/@34.4095978,133.2043775,17z/data=!3m1!4b1!4m2!3m1!1s0x355101aefb918809:0x69b535418652e8fa?hl=en

Whenever I see the URL on Google Chrome, texts are successfully changed into English. However, once I put the link in my Discourse forum, the Japanese texts remain as they are. They did not change into English.

The default language of this Discourse is English at the moment. I want to let my forum show English texts rather than the Japanese texts.

Please help me solve this issue.

Is you own location or site in Japan?

Yes, I am in Japan now.
