Is the train-loving population really this influential with their pocketbooks? The last year has seen an explosion in train-themed goods in Japan, from alarm clocks to banks to watches and everything in-between. Trains hold a special place in modern Japanese life, many of whom utilize the system every day.

Mokku, a maker of toys and novelty FMCG, has recently begun selling a series of green tea modeled after the famed Yamanote Line in Tokyo. Doing a full loop around the downtown area, the Yamanote is a key connector and an iconic line.

At about $3.50, these bottles go for about three times what a normal green tea does, so it’s really all about the bottle rather than the contents. Still, it’s an interesting twist to take the Yamanote which is known for its stark green color and merging it with a green tea.
