This is a Korean Karatsu flower vase by Kenji Okamoto (Sakurei Okamoto). It was in my grandfather's house, and at first, I didn't know who made it. There was a piece of paper with a brief biography, which identified the artist as Kenji Okamoto. After researching, I found out that he is Sakurei Okamoto. It is believed to be a piece created before he used the name Sakurei Okamoto. The birth year, training years, and independent year listed on the paper match Sakurei Okamoto's profile, so it is believed to be his work. The paper with the biography also includes a handwritten message, presumably by the artist himself. Please refer to the images for confirmation. The artwork itself is unused and in good condition, but the box has some stains. Please consider this when making your purchase.
