Usuda Deep Space Center Exhibition Hall is the public interpretation building beside JAXA’s deep-space communications complex in the mountains of Nagano. Free displays explain how the station’s antennas send commands to and receive scientific data from distant spacecraft; current visitor information also notes a permanent 1/4-scale SLIM lunar-lander model, while the outdoor route includes JAXA’s 5.5-billionths-scale solar-system model and views toward the antennas. JAXA lists exhibition access 10:00–16:00 and winter closure from mid-November to mid-April; contact +81-267-81-1230 to confirm seasonal status before travel. Free parking serves about 12 cars and two large vehicles by arrangement; wheelchairs and strollers can enter, with one free loan wheelchair. Lunch is allowed outside, and only guide or service dogs may enter the exhibition hall. Visitor address: 1831-6 Omagari, Kamiodagiri, Saku City, Nagano Prefecture 384-0306, Japan.
