Tsuchiya was born in
Tokyo to a Japanese mother and an American father (the surname of her father is Heider). In her earliest years, she spoke English and Japanese. Tsuchiya's parents divorced when she was seven. She has an older sister, Angela.
Tsuchiya's modeling career began at the age of fourteen after her older sister Angela, a former
fashion model, suggested it. She entered her sister's former agency, and was picked up by an agent who specialized in magazine-modeling, and her first jobs consisted of modeling for an open collection in
Kobe and for
Japanese Seventeen in 1998.
 Demand for her grew, and by 2002, she was doing television ads for
Tsuchiya spent her mid-teens modeling, and made friends, notably
Yoshika, and soon she began to stay at their apartments. It has been reported that she also began smoking and drinking around this time.
Inspiration for "Ichigo"
Her best known role in acting was as "Ichigo Shirayuri" - a rural-delinquent
biker-gang girl turned
fashion model - in the 2004 movie
Kamikaze Girls. Ichigo as a model was portrayed as one with tendencies for violent behavior and delinquency.
Blue Ribbon Award-winning role, quite different from one in the original work written by author and designer
Nobara Takemoto, was loosely based on Tsuchiya's actual story which she later revealed after the movie's release.
During her time as a model, she tried hard to lose weight. At 1.67 meters (5 feet 6 inches) and 44 kilograms (97 pounds), she was considered overweight for a model in Japan. At this time, she experienced mental and physical agony, being bullied by other models. According to a contemporary, those who teased Tsuchiya had recognized her as "tough" while other
"overweight" models, like
Kaela Kimura, were always called by extremely vulgar nicknames. Just a few, but some, praised Tsuchiya afterwards, saying things like "well done."
 When she was fifteen, she awoke one morning starving to find that she could not move her legs, a result of severe
malnutrition, and she was forced to drag herself by hand to the refrigerator.
Tsuchiya has also confessed
 publications she considered sub-stream. These models, unable to understand Japanese, were oblivious to Tsuchiya's abuse and always just smiled back to whatever what she said. Tsuchiya would also often speak to them in English using offensive words related to obesity, as many models in their teens do, and would often further assault them when they reacted negatively to her verbal abuse.
that when drunk, she often picked on "fatter" models herself, especially foreigners who came to work for fashion magazines such as
Tsuchiya retired from modeling at 18. She has said that she realized she could no longer compete with "gifted ones" like
Emi Suzuki. She remains in demand for fashion and lifestyle magazines like Kera, Soup, and Zipper.

Kyokushuzan held in
Ryogoku Kokugikan and presenting him with a bouquet, and appeared in his memorial photobook released on June 4, 2007.
Use of dialects
Although born and raised in Tokyo, she sometimes uses
Okinawa slang and speaks in southern dialects especially when she is drunk and on the radio . She has explained that the majority of models she encountered were from the southern islands or the north, so she learned slang from them. This helped the development of her character Ichigo, the
Bōsōzoku delinquent, in
