Despite the spread of computers and smartphones, calculators remain popular in Japan and abroad due to their convenience, while makers continue to create new types to keep up with trends and boost demand.
To mark 60 years since releasing its first calculator in 1965, Casio Computer released on Thursday 650 limited units decorated with Japanese lacquer hand-painted by Echizen artisans, at a suggested price of ?99,000 ($625).
