A 5-Day Time Slip to the Showa Era! The Showa Retro Hot Spring Bathhouse Tamagawa Onsen is Packed with Family Events

The day-trip hot spring and "Showa Retro Hot Spring Bathhouse Tamagawa Onsen" (Tokigawa-machi, Hiki-gun, Saitama), operated by Onsen Dojo Inc. (Tokigawa-machi, Hiki-gun, Saitama; CEO Toshiki Yamazaki), will hold a variety of events enjoyable for families over the five days from Saturday, May 2 to Wednesday, May 6, 2026. Events include "Showa Fair Games," "Shobu-yu (Iris Bath)," and "Picture Card Shows."

Tamagawa Onsen's concept is "Showa Retro." With the desire to share the charm of the Showa era with both generations who miss it and those who never knew it, the facility hosts various events. Guests can enjoy nostalgic Showa-era "Picture Card Shows," "Puffed Rice Demonstrations," and "Fair Games." Additionally, to coincide with Children's Day on May 5, "Shobu-yu (Iris Bath)" and a "Bingo Tournament" will be held. We hope families will spend their May Golden Week enjoying both the events and the hot springs.
