Hello from the Chiyoda-ku Mansion Information Center editorial team!

Today, we’re thrilled to share a real estate story that has the attention of high-end investors across Japan — a brand-new luxury hotel by Royal Hotel in the prestigious Arima Onsen area, set to open in February 2028.

Arima Onsen, one of Japan’s “Three Ancient Hot Springs,” continues to be a magnet for domestic and international travelers alike. With inbound tourism surging back to pre-pandemic levels, this is the perfect time for savvy investors to reexamine the area — especially with this new high-end development.

93 Luxury Rooms with Terraces in an 8-Story Building

Announced on June 24, 2025, the project will bring an 8-story luxury resort hotel with 93 guest rooms, each over 40 square meters with a private terrace. It’s a high-spec design aimed at affluent travelers seeking relaxing, slow stays.

The hotel will feature large communal baths, open-air hot springs, and a restaurant showcasing local cuisine cooked live in front of guests — combining healing, gastronomy, and tradition in a luxurious setting.

Why Now? The Perfect Timing for Arima Onsen Investment

This isn’t just another hot spring resort development. The move is backed by several key investment trends:

  • A strong rebound in inbound tourism (back to pre-COVID levels)
  • Increasing travel demand among wealthy and senior domestic travelers
  • Greater interest in the high-profit model of “onsen + real estate development”

Kansai is especially hot right now due to upcoming events like the Expo and IR (Integrated Resort). Among all, Kobe and Arima stand out for their balance of appeal and stability.

Royal Hotel’s Multi-Brand Growth Strategy

Royal Hotel is also launching hotels in Osaka’s Namba and Fukuoka in 2026, targeting younger travelers from Asia. With Arima, they’re now embracing the high-end senior market. This hybrid model — combining luxury ryokan and hotel — aims to set a new standard far beyond the typical business hotel.

For investors, this property offers excellent asset value, with strong potential for both operational income and capital gains.

Why This Project Appeals to Wealthy Investors

  • Limited hotel development potential in Arima means land scarcity and rising value
  • All rooms are spacious (40+ sqm), have terraces, and offer panoramic baths
  • Stable, high-price revenue potential from premium guests

This opportunity is ideal for:

  • Investors seeking co-investment with overseas high-net-worth individuals
  • Those planning for inheritance tax and wealth preservation
  • Buyers interested in rare hotel land in the Arima area
  • Operators exploring mid- to long-term vacation rental (minpaku) or leasing strategies

Conclusion: Arima Onsen is Transforming — Get In Early

The Royal Hotel’s 2028 project promises to redefine Arima Onsen as a next-generation resort. Investors focused on the future of Japan’s tourism and hospitality real estate should act before the grand opening.
