How about a Japanese tea set and some high-quality loose-leaf teas for your son's birthday? This gift will allow him to practice his tea ceremony skills and enjoy a delicious cup of tea. You could also consider booking a private tea ceremony lesson or workshop for him, to further develop his skills and knowledge. Another idea could be a traditional Japanese tea bowl, which would make a beautiful addition to his tea set and could be used in his tea ceremonies.
Or you can get him a star map with the date when he was born.
