What is Mitaka?
Mitaka is software for visualizing the known Universe with up-to-date observational data and theoretical models, developed by the Four-Dimensional Digital Universe (4D2U) project of the National Astronomical Observatory of Japan (NAOJ). Mitaka users can seamlessly navigate through space, from the Earth to the edges of the known Universe.
Mitaka was originally developed for 3D visualizations on multiple screens at the 4D2U theater in NAOJ's Mitaka headquarters. However, it can also be used on a single Windows PC.
4D2U has been supported by the National Astronomical Observatory of Japan (NAOJ) and other collaborating organizations including, Research and Development for Applying Advanced Computational Science and Technology (ACT-JST) ["Establishment and Application of Four-Dimensional Digital Space Data (led by Norio Kaifu, 2001 to 2004)"], as well as the Ministry of Education, Culture, Sports, Science and Technology [Effective Promotion Program for Industry-Academia-Government Collaborative Research supported by Special Coordination Funds for Promoting Science and Technology – "Establishment of Distribution System for Four-Dimensional Digital Video of the Universe (led by Shoken Miyama, 2004 to 2007)"].
System RequirementsRecommended Minimum Hardware Configuration
*) To use the software with Windows XP, select mitaka_VC.exe as the executed file.
The above configuration is recommended when not using topographic data. More memory and hard drive space will be required to accommodate the data if you use topographic data.
It is possible to run the program on slower computers by carefully modifying default settings to reduce the texture resolution, for example.
Hardware Configuration at the 4D2U Dome Theater at NAOJ
We have not tested other configurations. Please understand that we are not qualified to offer hardware recommendations. Some systems that meet the guidelines above may still have problems running the software.
We provide Mitaka for no charge and without any warranty.
This version does not include the topographic data and illustrations for the constellations. The topographic data can be downloaded separately from the links below. The illustrations for the constellations will be released later.

Mitaka for VR
This version is compatible with a head-mounted display (HMD) for virtual reality (VR). You can experience Mitaka version 1.4.1a in VR.
It supports Oculus Rift (CV1) and HTC Vive. The corresponding Oculus runtime version is 1.16.0 or later, and OpenVR version is 1.0.9 or later. Operation can be done with Oculus Touch or Vive controller (it can also be operated with game controller).
The Mitaka for VR works by adding a software to the regular version of Mitaka. Install the regular version of Mitaka, version 1.4.1a, and make it ready to use. Then, download the zip file for Mitaka for VR and copy the extracted folder with all files into the Mitaka folder. Keep the folder structure when copying the VR folder. For more details on its operation, please see the Readme_VR_E.txt file in the archive.Caution：
* Mitaka for VR Version 1.4.1a (September 8, 2017 Released)
Tsunehiko Kato (member of the NAOJ 4D2U Group) designed and developed the Mitaka software, including its algorithms for image rendering, data processing, and its Japanese manual. Sorahiko Nukatani (cooperative engineer from RIKEN) worked on the aesthetic design, including title design and color tables.
