Made in Japan
- When phrased this way, it is understood that the entire product was made in Japan.
If you would like, you can also say, "100% made in Japan."
"One hundred percent of this product was made in Japan."
"This product was made in Japan."
Authentic - original, genuine, not a copy
"This is an authentic Japanese product."
Made in Japan
- 日本製。このように表現するときは、まるごとの製品が日本で作られたものだと認識されます。
"100% made in Japan."
100％日本製という言い方もできます。
"One hundred percent of this product was made in Japan."
この商品は１００％日本製です。
"This product was made in Japan."
この製品は日本製です。
Authentic - original, genuine, not a copy.
オリジナル、純粋な、模倣品でない。
"This is an authentic Japanese product."
これは純日本製品です。
純 means pure, and 国産 means domestic product.
But saying "pure domestic product" sounds redundant (and unnatural), so you're better off just saying "local product" or "domestic product."
Of course, it depends what the product or item is. Most saleable items are made in factories or by hand and so we may talk about the manufacturing process with regard to many items:
"These cars are manufactured entirely in Japan." Entirely = totally in this case.
"That car was wholly made in Japan. No parts were imported."
もちろん、どんな商品かアイテムなのかにもよります。商品というのは普通向上で作られるか、ハンドメイドですよね。そのため、生産過程に関しては色んな言いかたができます。
"These cars are manufactured entirely in Japan." Entirely = この場合は、完全に、という意味
これらの車は完全に日本で生産されているんだ。
"That car was wholly made in Japan. No parts were imported."
この車は、最初から最後まで日本で生産されていて、ひとつの部品も輸入じゃないんだ。
「純国産」は100% made in...と言うことができます。
