Name: Sei Yotsuba (Pen name)

Age: undisclosed, but very experienced (30 years of learning English (with interruptions))

Gender: male

Location: Tokyo, Japan

Job: Engineer (research, planning, and education of young people)

Work Environment: surrounded with many smart people and TOEIC score 990 (perfect score) holders. In fact, I’m in a narrow position.

Hobby: Great detective (and a few mystery novels).

People I admire: Katsu Kaishu and Sherlock Holmes.

English Proficiency: mainly reading and writing, but I can score 495 (full score) on the TOEIC level. Overall: 950; I took the Practical English Proficiency Test when I was young and passed the Pre-1 level.

Fields of weakness: languages, music, and art. Worked hard for several decades to finally get the hang of English and achieve a score of 950. (In other words, he knows a lot about how English learners with no sense can effectively improve their English language skills.)
