During the period between 500 and 1500 AD, the Japanese made several notable inventions. Some of them include:

1. Movable-type printing: Although movable-type printing was invented in China, it was further developed and improved in Japan during the Heian period (794-1185 AD). This enabled the mass production of written materials.

2. Magnetic compass: The Chinese compass was introduced to Japan in the 7th century and was essential for navigation and mapmaking.

3. Samurai armor: The samurai armor, known as "yoroi," was developed during the Heian period and evolved into various styles over time. It provided protection to the samurai warriors during battles.

4. Folding fan: The folding fan, known as "sensu," was popularized during the Heian period and became a symbol of elegance and sophistication. It was widely used by the nobility and served as both a functional and decorative item.

5. Iron and Steel production: The process of smelting iron and steel was refined during this era, leading to the development of superior weaponry and tools.

6. Tea cultivation and ceremony: The cultivation of tea and the tea ceremony took root during the Kamakura period (1185-1333 AD) and became an integral part of Japanese culture.

7. Paper currency: During the Muromachi period (1336-1573 AD), the Japanese began to use paper currency, known as "gomasu." It was valued based on the weight of the coins it replaced.

These are just a few examples of the inventions and developments that took place in Japan between 500 and 1500 AD.
