I mean, in Japan they use the swastika and people do not feel disturbed.

The swastika (Sanskrit "good luck" or "well-being", literally "it is good") is a symbol which commonly appears throughout history. The name and first use of the swastika was first mentioned in the Vedas, the holy texts of Hinduism.

However, while its name is Vedic, it appears in art and design throughout human history, symbolising many different things; such as luck, Brahma, the Hindu concept of samsara, or Surya (the sun).

The swastika is used primarily as a symbol by Hindus, but transferred to followers of other Indic religions like Buddhists and Jains.
