At rather short notice, I have learned about this event, which is being held at King's College London Student's Union next Saturday (30th March) from midday until 5pm. The program concentrates on the traditional arts and crafts of Japan, although the word 'manga' can be found lurking near the bottom of the list. Admission is 50p.
