Rather than feed vending machines $1.40/per bottle for tea or water, stop by the big electronics stores in big cities in Tokyo – they often have huge bottles of both name-brand teas and/or water out front on sale for ¥100-¥150. Ten times the volume as vending machine bottles for around the same price. Big bucks savings.

Note the large bottles on the bottom rack.
