Hi, Thank you for your reply.
I have checked the Currency setting at WooCommerce.
It shows:
Currency: Japanese (yen mark) – JPY
Currency symbol position : Left
Thousands separator: ,
Decimal separator: .
Number of digits after decimal point: 0
Japanese yen does not need to show ‘Number of digits after decimal point’, so it set as 0.
I think the currency setting is correct. But the issue is persisted.
