Caught in the rain in Japan? You don't need to buy another plastic umbrella. iKasa is Japan's umbrella sharing service. Pick up an umbrella at a stand near you, keep it as long as you need, and return it at any other stand. No deposit. No key. ◆ HOW IT WORKS Setting up 1. Download the app and choose English 2. Sign in with Apple, Google or LINE 3. Register a credit or debit card, or Apple Pay Renting 1. Find a stand near you on the map 2. Tap Rent and scan the QR code on the stand 3. Turn the handle to the left and slide the umbrella out Returning 1. Find any stand on the map (you do not have to go back to where you rented) 2. Tap Return and scan the QR code 3. Fold the umbrella neatly and slide it back in ◆ WHERE YOU CAN USE IT - Tokyo - Kanagawa - Osaka - Saitama - Chiba - Hyogo - Kyoto - Ibaraki - Aichi - Nara - Okayama Open the map in the app to see the stands around you. ◆ WHY IT'S CONVENIENT - Rent anywhere, return anywhere — the two do not have to match - Stands at train stations, convenience stores, shops, offices and universities - No need to check the forecast before you go out - Return it when the rain stops and travel light again - Just scan a QR code. No counter, no paperwork, no deposit - No Japanese phone number or bank account needed - No wet umbrella to carry around a museum, a restaurant or a shop - No umbrella taking up space in your luggage - Glass fiber ribs that hold up in typhoons, heavy rain and snow - Large enough for two people, and usable as a sun umbrella on hot days ◆ WHY IT'S GOOD VALUE - From ¥140 for up to one hour - ¥210 for a full day, ¥420 for two days - No subscription and no sign-up fee - Far cheaper than buying an umbrella you will leave behind - You pay only for the time you keep it ◆ PLEASE NOTE Hokkaido, Fukuoka and Saga (except Tosu) use a different type of umbrella that this mode cannot unlock, so you can neither rent nor return there. If you are carrying an umbrella, please return it at a stand outside those areas before you leave Japan. If an umbrella is kept for more than 90 days it is treated as lost, and the total charge reaches ¥3,384.

Verdict
The clearest difference is in-app purchases: iKasa at none against hagu's 1. hagu's advantage is ads (none vs shown) and update cadence (every 2 days vs fortnightly). On price, device support and iOS requirement there is nothing between them.
