【Regarding Bike Replacement Work Starting Mid-March (Temporary Reduction/Mixing of Bike Models)】
Starting mid-March 2026, we will sequentially implement bike replacement work.
During this work period, the following situations may occur due to operational circumstances:
- The number of operational bicycles may temporarily decrease, potentially making usage more difficult than usual.
- Kotobike and Charichari bicycles may be mixed at ports.
*During the March replacement period, Charichari bicycles may be placed at Kotobike ports. However, Charichari bicycles cannot be used during March.
*Starting in April, kotobike vehicles may be placed at ChariChari ports, but these kotobike vehicles will not be available for use after April.
We apologize for any inconvenience this may cause our users. We kindly ask for your understanding as we strive to ensure a safe and smooth transition.
We will continue to work diligently to further improve our service and appreciate your continued patronage.
