Traveling from Saitama to Saku is primarily serviced by the Limited Express Azusa train, which provides an efficient connection between these two locations. The Azusa can reach speeds of up to 130 km/h (81 mph) and typically completes the journey in approximately 2 hours and 30 minutes, making several stops at key stations including Hachioji and Kobuchizawa.
This service offers both Standard and Green Car seating, allowing passengers choices based on comfort and budget. The Limited Express train features amenities such as reserved seating, onboard refreshments, and ample luggage space, catering to both business and leisure travelers.
Though the Azusa does not operate at high-speed train levels, it offers a reliable and scenic route through the mountainous regions of Nagano perfect for enjoying beautiful landscapes along the way. For those seeking a faster route, connecting to the Shinkansen at a nearby station may also be an option, but for a direct experience, the Limited Express Azusa remains a solid choice.
