Translation guide
The concept of a successor in English covers a person who takes over a role, position, or title, as well as a thing that replaces another. In Japanese, the most common and natural equivalent is 後任 (こうにん) for a person in a formal role, while 後継者 (こうけいしゃ) is used for inheriting a business, tradition, or legacy. For things, 後継 (こうけい) or 後継機 (こうけいき) are common. The choice depends heavily on context: whether it's a job, a family line, a product, or an abstract replacement.
When someone replaces another person in a specific role, especially in a workplace, organization, or official capacity.
The standard term for a person who succeeds someone in a post or duty. Neutral and widely used in business and formal contexts.

A slightly more formal version of 後任, explicitly meaning 'successor person'. Used in official announcements or documents.

A verb phrase meaning 'to succeed (someone)' or 'take over a role'. Often used for family businesses or traditional roles, but can apply to jobs.

When someone takes over a family business, artistic tradition, or carries on a legacy, often implying a longer-term or more personal succession.
The most common word for a successor in the sense of an heir or someone who carries on a business, tradition, or legacy. Often used for family businesses, crafts, or leadership.

Specifically an heir, often used for family lineage or inheritance of property/business. Slightly more traditional and personal than 後継者.

Used for a successor model of a device, machine, or vehicle. Common in tech and manufacturing contexts.

A shorter form meaning 'successor' for things, often used in compounds like 後継商品 (successor product). Can also refer to people in some contexts.
Similar to 後継機 but less common; emphasizes the sequence or following model.

Can be used abstractly for things like 'successor to a theory' or 'successor organization'. Often part of compound nouns.

A phrase meaning 'something that succeeds/takes over from ~'. Flexible and can be used for abstract concepts.
後任 (こうにん) is for a direct replacement in a specific job or post, often temporary or rotational. 後継者 (こうけいしゃ) implies a longer-term inheritance of a business, tradition, or role, often with a sense of legacy. Use 後任 for a new manager; use 後継者 for the son taking over the family company.
The English word 'successor' is broad, but Japanese requires choosing the right term based on context. Using 後継者 for a temporary job replacement can sound odd. When in doubt, 後任 is safer for professional roles.
The lack of successors is becoming a problem.
