The Lion (ライオン) is a Japanese camera using the no-need-darkroom process, reportedly advertised by the company Tamura Nisshindō from February 1931, at the price of ¥3.80. It is said that the first advertisement appeared that month in Asahi Camera. The camera was probably shaped as a box, but this is currently unsure. No surviving example has been observed so far.
