Overview
Shibukawa (渋川) sits at the geographic center of mainland Japan—hence its nickname "the belly button of Japan." The city is the gateway to Ikaho (伊香保), a beloved hot spring resort town with historic inns, mountain views, and the quirky Heso Matsuri (belly button festival). It is a practical overnight stop between Tokyo and Nikko or Nagano, offering a quieter, cheaper alternative to major tourist hubs.

Before you go
Connectivity
Japan has excellent mobile coverage; major carriers (NTT Docomo, SoftBank, AU) offer prepaid SIMs and pocket WiFi rentals at airports and convenience stores.
Culture
Shibukawa hosts the annual Heso Matsuri (belly button festival), celebrating its location at Japan's geographic centre. Ikaho is also a historic hot spring resort with traditional atmosphere.
Language
English signage is limited; a visitors centre at Shibukawa Station provides maps but with "poor English." Basic Japanese phrases or a translation app is helpful.
Money
Japan is overwhelmingly cash-based in smaller towns. Carry sufficient yen for Ikaho, where many hotels, restaurants, and shops do not accept credit cards.
Transport
Shibukawa Station is a regional rail hub on the Jōetsu Line; the nearest Shinkansen stop is Takasaki (30 min away by local train). Buses to Ikaho depart regularly from the station forecourt.
