Japan does not share its borders with any other country. It is an island.
Japan only has sea/ocean borders. It is an island.
Japan has no neighboring countries. It is an island
'border'- the edge of something. When we talk about countries, it is the line that separates two countries.
'neighboring countries'- a 'neighbor' is someone who lives next to you. A neighboring country is the country next to yours which you share a border with.
"Japan does not share its borders with any other country. It is an island."
Here you are explaining that Japan doesn't have any neighboring countries share its borders with it because it is an island.
"Japan only has sea/ocean borders. It is an island."
Here you are explaining that Japan only has seas or oceans as its borders because it is an island.
"Japan has no neighboring countries. It is an island"
Here you are explaining that Japan does not have any neighbor countries because it is an island.
I hope this helps :)
"“Border”は何かの端のことです。国の話をする時には国境を意味します。“Neighboring country”の”neighbor”は隣人を指します。したがって”Neighboring country”は国境が隣り合わせの隣国のことです。

Japan doesn't share its borders with any other country.
Japan doesn't border any other country.
to share your borders with another country - this means that a nation borders at least one other country
e.g. The United States shares its northern and southern borders with Canada and Mexico, though it borders the Atlantic Ocean on the East and the Pacific Ocean on the West.
to share your borders with another country - 少なくとも1つの国と国境を共有していることを意味します
【例文】
The United States shares its northern and southern borders with Canada and Mexico, though it borders the Atlantic Ocean on the East and the Pacific Ocean on the West.（米国は北と南の国境をカナダとメキシコと共有しているが、東は大西洋、西は太平洋に接している）
You can simply say:
Japan is an island.
That automatically means that it does not touch any other countries.
United Kingdom would be an example of another island.
I hope that helps!
シンプルに

ということができます。
こういうと、当然日本は他の国に接していないことがわかります。
United Kingdom（UK）も同じく island（島）ですね。

Japan is a sovereign island nation in East Asia. Located in the Pacific Ocean
>Japan is a island in East Asia. Located in the Pacific Ocean.
*Island=a tract of land completely surrounded by water, and not large enough to be called a continent.
Japan is a island in East Asia. Located in the Pacific Ocean.
*Island=大陸と呼ぶほど大きくなく、周りを水に囲まれた地域を意味します。
Japan is an island and has no neighboring countries
You can say :
Japan is an island and it is surrounded by sea
Japan is an island and has no neighboring countries
(This explains that Japan stands alone)
このように言うことができます。
Japan is an island and it is surrounded by sea.
Japan is an island and has no neighboring countries.
（これで日本は島国でどことも接していないことを意味します。）
1. Japan is an island surrounded by water.
An island is a piece of land surrounded by water. Japan is an island so this means it is surrounded by water, and it is not touching any other country.
1. Japan is an island surrounded by water.
island（島）は水に囲まれた陸地です。日本は島ですので、水に囲まれており、他国に隣接していないという意味です。
1. Japan is distinctly, a Japanese island dominion and does not share any island with another country.
2. The islands which constitute the entire Japanese nation, are not shared with any other country.
An island, by definition, does not touch any other countries - but clearly, part of an island may have shared sovereignty as is the the case with Ireland and Northern Ireland. To communicate this entire meaning in a short sentence is not so easy! The second example is probably the neatest of the two.
Distinctly - that can be easily seen/is separate or different to
Dominion - the area a government controls
Sovereignty - jurisdiction
Japan is an island. It is not bordering any other country.
If you say 'Japan is an island' it means that it is surrounded by sea and it does not touch any other countries'. You do not need to explain this as the definition of island is 'land that is surrounded by water'.
Ireland is also an island. :)
Japan is an island' と言うと、「日本は海に囲まれていて、他の国と接していない」という意味になります。'island' の定義は「周囲が水で囲まれている陸地」なので、これについて説明する必要はありません。
アイルランドも島です。 :)
We would use the word, "island (島)," to express that it is completely surrounded by water and that no other country or land mass touches or connects with it.
We use the word border to explain the place where two countries meet. Since Japan is an island, we say it has no land borders. Japan only has sea borders. We can also use the phrase island nation to describe countries like Japan and my home country, UK!
Japan does not share its borders with any other country. It is an island.
Japan is an island and has no neighboring countries
Neighboring adjacent to, bordering, or nearby. Although they seem like a different sentences, you should feel both of them as they have similar meaning.
