How to say "subscriber" in Japanese

Choosing the right word
  • 登録者とうろくしゃCommon
    nounThe broadest choice: a person who has registered or signed up with a service, website, or channel. It stresses the act of signing up rather than payment.
  • 愛読者あいどくしゃ
    nounA devoted reader: someone who reads a particular magazine, newspaper, or author regularly and with affection. The nuance is loyal, fond readership rather than the transaction of subscribing.
    彼かれはスティーヴン・キングの熱心ねっしんな愛読あいどく者しゃです。↗
    He is a keen Stephen King fan.
  • 購読者こうどくしゃ
    nounThe straightforward word for someone who pays to receive a publication such as a newspaper or magazine. Choose this when 'subscriber' means a paying reader of a periodical.
    この新聞しんぶんは購読者こうどくしゃが多おおい。↗
    This paper has a large circulation.
  • nounA loanword used mainly in technical fields such as telecommunications and computing, for a user under contract to a service. In ordinary contexts it is seldom the word you want.
  • 予約者よやくしゃ
    nounEssentially a person who makes a booking or reservation. Its 'subscriber' sense is marginal — someone reserving copies of a magazine in advance — so it is rarely the word you want.

Use 登録者 for someone signed up with a service or channel, 購読者 for a paying reader of a periodical, 愛読者 for a devoted reader, 「サブスクライバー」 in technical contexts, and 予約者 hardly ever for this sense.
