If you were a school teacher with an interest in Japan, how would you introduce Japan in your classroom? In geography lessons? You might perhaps organise a Japan week, or run a Japan club at lunch time, or after school. For teachers of many different subjects, there are aspects of Japanese culture which will be relevant. Haiku feature in the primary curriculum, but have you tried using the soroban (abacus) and Japanese numerical concepts in mathematics lessons, or drawing manga-style self portraits?
There are surprisingly many areas of the curriculum which can be enhanced by the introduction of a ‘Japanese’ theme and students really enjoy learning something new.
