Every session helps Grandma Ume run her little stationery shop:

• Brain Age Check — three short tests give you a kind, personal brain age
• Daily hanko stamp — press it anywhere on today's calendar square; its position and tilt are yours forever
• Streak-powered sumo rank ladder, from Maezumo all the way to Yokozuna
• Collectible milestone stamps in your own goshuin book
• A shop with hanko inks that recolor every stamp in the game
No pressure, no long sessions — just two minutes a day to keep your mind sharp and your calendar a little more yours.
