Japan Highway Bus Scraper (Kosokubus)

Extracts Japanese intercity highway-bus timetables and fares from Kosokubus.com — Japan's largest bus booking aggregator. Covers Willer Express, all six JR Bus regional subsidiaries (Kanto, Tohoku, Chubu, West, Shikoku, Kyushu), Sakura Kotsu, Keio Bus, Odakyu City Bus, Meitetsu Bus, Kintetsu Bus, Hankyu Bus, and 30+ other operators. Returns structured records per route with seat class, amenities, overnight flag, fares in JPY, and live availability.

Japan Highway Bus Scraper Features

• Search any origin-to-destination prefecture pair using 5-digit prefecture codes (e.g. 00013 for Tokyo, 00027 for Osaka)
• Leave origin/destination blank to crawl all major corridors automatically
• Filter by overnight-only service, seat class (4-row standard, 3-row relax, 2-row executive, Cocoon pod), or female-only seating requirement
• Extracts 26 fields per route including operator name (Japanese + English romaji), all boarding/alighting stops, departure/arrival times, journey duration, fares, amenities, and direct booking URLs
• Cap total results with maxItems to retrieve a quick sample without crawling full corridors
• Runs on residential Japanese proxy for reliable geo-consistent results

Who Uses Japanese Bus Timetable Data?

• Travel aggregators — build or update Japan bus search engines with structured route, fare, and availability data
• Inbound tourism apps — show visitors affordable highway-bus alternatives to Shinkansen, with seat-class breakdowns and overnight options
• JR Pass calculators — surface competing bus fares on covered corridors to help travelers decide whether a pass makes sense
• Transport researchers — map intercity bus networks, track fare changes, or analyse operator coverage by prefecture pair
• Price monitoring tools — alert on fare changes or availability drops for specific corridors

How Japan Highway Bus Scraper Works

1. You supply origin and destination prefecture codes (or leave them blank for major corridors).
2. The scraper fetches the Kosokubus bus-list page for each corridor — a fully server-rendered HTML page listing all routes, no JavaScript needed.
3. Each route card is parsed: operator, stops, seat class, amenities, fares, and availability are extracted and saved as a structured record. Filters (overnight, seat class, female-only) are applied before saving. The scraper stops when maxItems is reached.

FAQ

How many routes can this scraper collect? Kosokubus lists all routes on a single corridor page with no pagination — typically 1 to 20 routes per prefecture pair. Active corridor count across all pairs is estimated at 1,000 to 3,000 routes nationwide. A full multi-corridor run returns proportionally more.

Does it handle all operators? The scraper extracts whichever operators Kosokubus lists for a given corridor. Willer Express, all six JR Bus subsidiaries, Sakura Kotsu, Keio Bus, Odakyu City Bus, Meitetsu Bus, Kintetsu Bus, and Hankyu Bus all appear in typical runs.

How fresh is the data? Timetable data (routes, stops, durations) is static and updated seasonally. Availability (seats remaining) and fares change daily — run the scraper on your schedule to keep those fields current.

What does it cost to run? Each run has a $0.10 start fee plus $0.001 per route record. A 100-route run costs roughly $0.20. A full 1,000-route corpus costs around $1.10.

Why do I need a Japanese residential proxy? Kosokubus returns geo-consistent content to Japanese IPs. Without a JP proxy, some corridors may return empty results or slightly different data. The scraper defaults to Apify residential proxy with country set to Japan.
