I. Love. This. Store.
I think the shopkeeper, Yoichi-san, alone makes this the best stationary store experience ever. He is very helpful and sweet, but also allows you to spend as much tome as you need in any section, so you never feel weird for contemplating one paper clip over another for 25 minutes.
As for the products, WOW! Way more fun designs than Muji (RIP ) but still remain true to the utilitarian and simple Japanese design philosophy. I'm talking about the Toshiyuki Kita, Naoto Fukusawa, Fumie Shibata type of aesthetic philosophy. You won't find any kawaii stickers, Sanrio toys, or anime merch here. This place is for those who value simplicity, but aren't afraid of bright colors.
You can get t-shirts, pens, organizing pouches, wall art, pens, pencils, wallets, rulers, clips, folders, and of course notebooks and planners. Everything is priced fairly (which isn't something I can say about Poketo which is right around the block) and Yoichi always makes sure that you are buying the best version of a product available. He's a lovely and genuine person, which is rare to find among shopkeepers in America.
The ROW is a lovely open air shopping square in general, and has a huge parking lot. I think the best establishment is Hightide though. Even the fancy restaurants pale in comparison!
