Osaka Naniwa Suzu-ki

Tinware is said to go back to the era of envoys to the Sui dynasty or (early 7th century) to the beginning of the Kamakura period (1185-1333).
Tin is a good material for sake holders and cups, tea-utensils and flower vases because it purifies water.
The high degree of airtightness also makes it the best canister for tea.
Being pliant, tin is not an easy material for machine work so the main part of the process is undertaken minutely by hand.
