The annual meeting of the Biophysical Society of Japan is held once a year in autumn or winter. The number of presentations is usually over 1,000.
The meeting is basically held in English. Members of the Australian Society for Biophysics or those who belong to foreign institutions can present their work at the meeting without a membership of the Biophysical Society of Japan.
The detail of the 56th Annual Meeting is linked here. The meeting will be held in 15-17, Sep. 2018 at Okayama, Japan.
