聖杯（せいはい、seihaい）
- Holy Grail

The Japanese word 聖杯 (sei-hai) directly translates to "Holy Grail" or "Sacred Cup" in English. It refers to a chalice or vessel believed to have been used by Jesus Christ at the Last Supper. The word carries strong connotations of sacredness, mystery, and a quest for something of great value or spiritual significance. In modern usage, 聖杯 can also symbolize an ultimate goal, a treasure, or a highly sought-after object or achievement.

聖杯 is primarily used in written and formal contexts. However, it can also be used in everyday conversation to describe something that is highly valued, difficult to obtain, or represents the ultimate achievement. It is often used figuratively rather than literally, especially in discussions about goals, aspirations, and quests.

聖杯 is typically written with the kanji 聖 (sei - holy, sacred) and 杯 (hai - cup, goblet). The reading is せいはい in hiragana. There are no other common ways to write this word. The okurigana is standard.

⚫︎ 宝物 (takaramo no) - treasure ⚫︎ 究極の目標 (kyūkyoku no mokuhyō) - ultimate goal ⚫︎ 理想 (risō) - ideal ⚫︎ 至宝 (shihō) - treasure; greatest treasure
