Summer “Umi no Hi” – Japanese Kanji Symbols for the Ocean Day 投稿者: japanese-kanjisymbols 投稿日: 2011/07/182011/07/05 I wrote “Umi no Hi”. It means the Ocean Day in English. Also, it’s known as Marine Day or Sea Day. “Umi” means Ocean and Sea “No” means of, -‘s, and so on “Hi” means Day The 3rd Monday of July, It’s “Umi no Hi“. It’s national holiday. Because Japan is an island among the seas, most prefectures contact with the sea. The sea is close for us. What is your favorite word about season? I’m waiting for a request.
