After searching the internet, I've concluded that it's likely a Konilette 1. About five years ago, I bought it at an antique market, described as a rare bellows camera. I didn't have much knowledge about the product at the time. It's quite small, and it was released in 1953. It seems it was a strategic, low-priced product to popularize cameras. Even so, the original price was ¥5300. This was almost a month's salary for a university graduate civil servant, whose starting salary was ¥7650. However, in an era when the Canon S II, a copy of the Leica, cost ¥48000, this low price was very appealing, and it seems that quite a few were sold. I've never actually used this camera to take photos, but from what I've seen online, it seems that it takes photos of decent quality, despite its rather cheap appearance. The special film used at the time is no longer available, but it seems that the "Tori-kkiri Konica" film, which Konica had previously made a big hit, can be used. Judging from the website, it seems that it can take photos of considerable quality. It's a very cute camera, as shown in the photo, and the bellows-style extending lens part would likely appeal to people today. This particular one seems to be in relatively good condition, and there don't seem to be any holes in the bellows. My other hobby, radios, has recently taken up most of the space, and due to space constraints, I'm going to sell it. I see that they are being sold for quite a high price online. I don't intend to make a profit from this, so considering the condition, I think it's a pretty good price.
