The question “how old is Yamamoto” is ambiguous because many well-known people and characters share that surname.

Most likely guess: Yoshinobu Yamamoto (MLB pitcher)

If you are asking about Yoshinobu Yamamoto , the Japanese pitcher for the Los Angeles Dodgers:

  • He was born on August 17, 1998.
  • That makes him 27 years old as of early 2026.

Other famous “Yamamoto”

A few other “Yamamoto” figures people often mean:

  • Genryūsai Shigekuni Yamamoto (from Bleach): a fictional Soul Reaper captain whose age is given as over 2,100 years old in series materials.
  • Hisaye Yamamoto , Japanese American writer: a real person, but your question does not specify her, and “how old is she now” is less commonly asked in current trending discussions.

Quick forum-style clarification

If your question comes from a forum or trending discussion, people asking “how old is Yamamoto” lately are usually referring to the Dodgers’ pitcher, especially after his recent MLB seasons and contract.

If you meant a different Yamamoto (anime character, another athlete, historical figure), reply with who specifically, and the exact age can be narrowed down.
