Introduction
Nestled in the bustling heart of Tokyo, Tokyo Somei Onsen SAKURA offers a serene escape, blending the tranquility of a traditional Japanese hot spring with urban accessibility.
Located in Toshima Ward, this natural onsen is celebrated for its mineral-rich waters, diverse bathing facilities, and elegant ambiance, earning it the nickname “Beauty Hot Spring.” Popularized by YouTuber Ben-san in his “Japan Ramblings” series, SAKURA has become a must-visit for travelers and locals seeking relaxation. This summary highlights its key features, from its therapeutic waters to its comprehensive amenities, making it an ideal stop for a rejuvenating day trip in Tokyo.

It’s an 8-minute walk from Sugamo Station (JR Yamanote Line or Toei Mita Line) or a 10-minute walk from Komagome Station (JR Yamanote Line or Tokyo Metro Namboku Line). For added convenience, a free shuttle bus operates from Sugamo Station’s south exit, with schedules available on the official website (sakura-2005.com). A video guide in English on the website assists international visitors in navigating from Sugamo Station to the shuttle stop, reflecting SAKURA’s commitment to accessibility for global travelers.
Operating Hours and Admission Fees
SAKURA operates daily from 10:00 AM to 11:00 PM, with last entry at 10:30 PM, offering ample time for visitors to unwind. Admission fees vary slightly across sources: adults may pay 1,296–1,800 JPY on weekdays and 1,320–2,130 JPY on weekends, while children (ages 3–11) are charged around 756–880 JPY. Infants under 3 enter free. Due to potential price adjustments, especially post-renovation in August 2025, checking the official website for the latest pricing is recommended to ensure accurate budgeting.
Natural Hot Springs and Bathing Options
The cornerstone of SAKURA’s appeal is its 100% natural hot spring water, sourced from 1,800 meters undergroundwith a flow rate of 500 liters per minute. The water, a sodium-chloride strong salt spring enriched with iodine, boasts a temperature of 48.8°C and is renowned for its skin-beautifying properties, earning the “Beauty Hot Spring” moniker.
The water’s amber hue upon air exposure adds a unique aesthetic, though some pools are filtered to appear clear. SAKURA offers 11 distinct bath types, including amber-colored hot springs, carbonated baths with white foam, open-air baths with starry skies or rock garden settings, and cypress-wood indoor baths. Additional options like jet massage baths and cold plunge pools cater to varied preferences, ensuring a personalized bathing experience.
Rock Bath and Additional Amenities
Beyond hot springs, SAKURA provides a rock bath (ganbanyoku) experience, where guests lie on heated mineral stones to promote sweating and metabolism. Priced at 864–1,320 JPY for 25 minutes (including bathrobe and towel), this service is ideal for those with cold extremities or seeking detoxification.
The facility also features a restaurant (10:30 AM–10:30 PM) serving Japanese banquet meals, Italian, and French cuisine; a relaxation lounge with tatami and sofas; massage and seitai services (10:30 AM–10:20 PM); a hair salon and aesthetic salon (10:30 AM–10:00 PM); and Korean scrub services. Secure lockers ensure safety for valuables, making SAKURA a comprehensive leisure destination.

To maintain a respectful and hygienic environment, SAKURA enforces strict rules. Photography is prohibited, towels must not touch bathwater, and children under 6 or those in diapers are barred from pools. Visitors with tattoos, intoxicated individuals, or women during menstruation may be denied entry.
