Michael HENRY sensei and his students had came our lab(basement) other day.
Michael sensei is the at the associate professor Shibaura Institute of Technology.
And they had the field trip to IIS as the part of the student seminar in this time.
They have observed the basement equipments and talked and laughed.
This visiting at Kuwano lab was not main, just came by to see Kuwano-sensei.
Kuwano-sensei said “About 8 years ago? Michael-sensei was able to speak Japanese only a little”.
But now he can speak perfect Japanese fluently. Kuwano-sensei was very surprised.
