I think Watashi no Heya is one of the most Jiyugaoka-like shops. It has the style of elegant but not too formal, putting importance on comfortableness, warm and cozy atmosphere.
Watashi no Heya (means "my room") is interior goods shop on Sunset Array street which opened in 1982. Over 25 years, the shop has been loved by neighbors throughout all generations.
While they have a style in idea for comfortable life, their items are not too edgy so that fit all life styles.
