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.
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.
Download the software using the following links.

How to Use the topographic data:
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.
