tengu; long-nosed goblin
A mythical creature from Japanese folklore, often depicted with a red face and a long nose, said to live deep in the mountains. Also used in expressions related to arrogance.
Tengu often appear in Japanese folk tales.
Listening to him brag, I felt like taking him down a peg.
The flattery from those around him made him conceited.
天狗になる vividly evokes becoming conceited (like the boastful tengu), while 自惚れ is the plain noun for vain self-admiration in general.
天狗になる is a colorful idiom for growing conceited after success, whereas 慢心 is the formal, neutral term for the same overconfidence.
天狗になる is a vivid, colloquial idiom for getting a swelled head, similar to うぬぼれる but more informal and image-based.

Standard kanji spelling for both the mythical creature and the idiomatic sense.
The word 天狗 (tengu) is of Chinese origin, originally referring to a celestial dog or comet, but in Japan it evolved into the well-known long-nosed goblin of folklore. The idiomatic sense of 'braggart' comes from the tengu's traditional depiction as arrogant and self-important.
