He wears a green Power Rangers costume and he assists the elderly, young mothers with children and people with heavy baggage get around the Tokyo subway. His name is Tadahiro Kanemasu, and he’s a hero to those who come in contact with him.

Kanemasu, 27, has a day job -- he’s a grocer. Seeing children while on the job inspired him to be a good Samaritan at one subway stop, where he’s been helping out riders for the last three months.

The 27-year-old subway superhero’s co-worker, Hayato Ito, told Reuters that Kanemasu’s kindness was always one of his traits.

"There were hints of this from a long time ago but finally he flowered as a hero," Ito said.

Kanemasu told Reuters that he’s thinking of expanding his superhero venture and is trying to recruit additional good Samaritans to join him on the subway.

The 27-year-old said it took time for subway riders to adjust to his good deeds.

"When I first began, people basically said 'Get away from me, you weirdo,'" he said. "Now they still think I'm weird but in a good way."

Among the help Kanemasu gives in his Power Ranger outfit is assisting mothers with baby strollers and hauling heavy bags for struggling passengers.
