Take Red line subway to Nakatsu station (M-15), the next stop after Umeda Station. Leave the station via exit number 4, which drops you on the sidewalk pointed in the correct direction (south).
Turn left onto the street just under the edge of the elevated train line. Do NOT cross under that line. Walk about 8 blocks; you’ll cross under an elevated highway (Shin-Mido-suji Ave), and then cross under a rail overpass (JR Kyoto Line). In the very next block on the left you will see a brown awning with a yellow “Y” on it, you found it.
Her hours are 0730-1030 (M-F) and 0800-1100 (S). She is closed on Sundays and holidays.
