Need help on online translation

I am planning my Japan trip and my biggest problem is understanding the websites as there are mostly in Japanese.
I have seen several messages that mentioned you can use google or firefox translation. I have never used such functions and I am very inexperienced in this field.
Is it possible that anyone can teach me here how to check translations or must I enquire it elsewhere ?
I can recognise or figure out the places name in kanji but nothing more.
Thank you.

Type 'translate' in your google search bar, top of he results should be 'Google Translate', open that page, then there'll be a box where you can enter text or web pages to be translated and drop-down menus to choose which languages. Just cut & paste the URL of the page you want into that box and ensure English is selected, it normally works for me.
