Sesto Senso, Shinjuku Takashimaya

Cool place to just wander around even if you're not buying anything, but the layout can be a bit hard to navigate through and the very few maps on each floor are not very helpful.

This department store provide prayer rooms for Muslims, you can find it on the 11th floor. Thank you Takashimaya

Very very big department store, all very well priced for Australian tourists even after tax. 90% of purchases are tax free for foreigners. Staff are all very friendly and helpful even if you're just browsing
