Japanese Cobalt Blue Teapot + 5 Cups Peacock/Floral/Gold Trim Bamboo Handle VTG

Vintage Japanese made porcelain cobalt blue small Teapot with bamboo handle + 5 matching round handleless teacups. Colors are- cobalt blue, lighter blue, orange, green floral, gold gilt trim & gold peacocks.  Teapot- there are 4 peacocks on the teapot, 2 on the front + 2 on the back. It measures 6.5 high (up to the top of the handle) x approximately 6 wide. It will hold up to 20 oz of liquid. It has a small Bamboo wrap handle. It's round in shape.  Condition: very good with some mile marks/wear from preowned use, no chips or cracks. There is still a small amount of residue from where the sticker used to be on the bottom, that said 'made in Japan.'   Teacups- small round, handleless, with 2 small peacocks & floral on one side + gold gilt rims. They measure just under 3 in diameter & are 2 high. The inside color of the cups is a white base.   Condition: Very good with slight wear/marks. Inside of the cups have what appear to be flecks from imperfection manufacturing (not sure), please see photos.   I believe these were made in the 1980's based on my research, however I cannot affirm the exact decade or year.
