Translation guide
The country name 'Japan' is expressed in Japanese as 日本 (にほん or にっぽん). にほん is the standard reading in most contexts, while にっぽん is used in formal, patriotic, or official situations. When referring to Japan as a location, the particle に is used for 'in/to Japan', and で for 'in Japan' (place of action). In many contexts, 'Japan' is omitted when it is clear from context.
Referring to the nation of Japan in general statements, as a subject, or as a location.
The standard, everyday name for Japan. Used in most contexts: news, conversation, and writing.

Both readings are correct. にほん is used in everyday speech and most writing. にっぽん is used in official names (日本銀行, 日本郵便), sports events, and to evoke national pride. There is no strict rule, but にほん is safer for learners.
When the context is clear, Japanese speakers often omit the subject or location. For example, 'I came to Japan last year' can be simply '去年来ました' if it's obvious you mean Japan.
