Developing MAUI version of SOKUTAKU

Xamarin support has ended, and we are currently updating EVNTA and SOKUTAKU to their MAUI versions. We plan to release SOKUTAKU first. As of February 2024, it is approximately 80% complete.

If anyone is considering a new mapping app, please contact us at We will only charge royalties for revenue generated from completed apps; there will be no fees for development. However, please note that we may not be able to accept development requests based on the content of the app. Thank you for your understanding.


Last year, I was unable to provide enough support for EVENTA due to other contract work. I apologize for any inconvenience caused.
From this year, I will be able to keep time for the development and support of EVENTA, so if you have any questions or comments, please contact
Also, if you have any proposals such as joint development of new businesses, please contact us as well.
Best regards,

The end of service of Soktaku and Soktaku driver


Please note that the provision of Soktaku and Soktaku drivers will be terminated at the end of July this year.  It is because the map display is no longer possible due to the end of the provision of map information (free version).

Regarding taxi call center information, it is provided by the separately provided application “EVENTA”, so please use this. If you tap the event group (sky tree icon on the upper right) of “Eventa” and select the “Taxi, Transportation” group, the taxi call center will be displayed on the map, so tap the phone number displayed by tapping the icon. You can make an immediate telephone reservation. You can easily make a telephone reservation without spending time searching for a taxi reservation destination on the go or in an emergency.

Thank you for using Sokutaku and Sokutaku Driver for a long time. In the future, we would like to proceed with further version upgrades of “EVENTA” and other application development, so if you have any opinions, requests, “, we would appreciate it if you could contact us. ..

Soktaku usage example (1)

Use the Soktaku self-position notification function

How to know the position when your smartphone is lost

If you are a Sokutaku user and there is no other person to notify you of your location,
If you register your own address, in the unlikely event that you lose your smartphone,
From other smartphones (smartphones with Soktaku installed)
You can check the location of your lost smartphone by logging in with the address.

However, Soktaku must be running on the lost smartphone.
(I think it’s a good idea to start it in the background)
