I would like to travel across Japan by bike, from Kagoshima to Hokkaido!
"Would like" is the way to talk about something that you want to do but are not able to at the moment. When you use some form of transportation, you want to make sure that you use the word "by" beforehand.
I hope that this helps :)
I hope to traverse Japan by bike from Kagoshima to Hokkaido
In the UK, the two extremities are John O Groats in the north of Scotland and Lands End in the south of England. This route is a common challenge for both cyclists and walkers. If you just say "I want" it does not indicate any intention or particular enthusiasm whatsoever. In the UK we would automatically use slightly more enthused vocabulary to denote either a future intention, a fixed plan or a dream that will never happen.
"I'd love to travel the entire length of Japan from south to North."
大英国の最北端がスコットランド北部にあるJohn O Groatsと言い、最南端がイギリス南部にあるLands Endと言います。このルートは、サイクリストや歩行者の共通課題です。
もし、単に"I want"（○○したい）と言うだけなら、熱意も意思も伝わらないでしょう。英国では、もう少し熱い言葉で、将来の願望、明確な計画、または、叶わぬ夢などについて語ります。例："I'd love to travel the entire length of Japan from south to north."（南から北まで日本縦断の旅が出来たら最高だ。）
I would like to cycle from one end of Japan to the other.
This answer is the quickest and most direct way of saying that you would like to cycle from the most southern point of Japan to the northern tip.
The word 'point' in this context means the bottom of a country or island, and the word 'tip' means the top.
If going from north to south, or south to north, this journey would be considered going between the 'ends' of the country. If you were to cycle from the west to east or east to west this would be going from one 'side' of the country to another. "I would like to cycle from one side of Japan to the other."
この答えは、最南端から最北端まで自転車で行きたいということを表現する最短、最直な言い方です。
この文脈での「point」は、国や島の下部で、「tip」は、最上のことを意味します。
北から南、南から北に行くならば、この旅行は国の端から端へ行くといえるでしょう。西から東、または東から西に行くならば、国の一方から他方にいくと言えるでしょう。
