Japan High Stash ISP|Japan Yahoo Auction Data Crawling and Price Monitoring

Japan's Yahoo auction to engage in data crawling? Solve the IP problem first

Do the Japanese market partners know that the real-time price data of Yahoo Auction is gold. But a lot of people just get started on the IP ban - just grabbed two days of data, the account directly scrapped. There are a lot of doorways here.The focus is on proxy IP selectionThe Japanese platform is particularly sensitive to domestic access. Ordinary residential proxies look hidden, but encounter high-frequency requests are still exposed, especially Japanese platforms are particularly sensitive to domestic access.

High stash ISP agents are the real deal

Get the right tools for data capture, here are the recommended onesTakanashi Proxy for Local ISP Lines in Japan. Three hardcore advantages of this type of IP:

Focusing on ISP proxies, this kind of IP goes directly to the real user segments of local Japanese broadband operators' lines, such as NTT East Japan and KDDI, which are big players. Server-side detection shows exactly the same network environment characteristics as the average Japanese Internet user.

Practical operation manual (guide to avoiding pitfalls)

Take ipipgo's Japanese ISP proxy as an example, and pay attention to these 4 steps for specific value allocation:

1. Select in the backgroundTokyo or Osaka Node(These two cities have the largest IP pools)
2. Use API to extract new IP before each request, it is recommended to set 5-10 seconds replacement cycle
3. Remember to include the Accept-Language: ja-JP parameter in the request header.
4. controlling the frequency of acquisition.No more than 300 requests per hour from a single IP

Here is a pit to note: do not use more than one proxy service provider at the same time, different IP segments of the access characteristics of the mixed but easy to be recognized. We have tested the continuous use of ipipgo single service, stable run over 15 days did not trigger any wind control.

Special techniques for price monitoring

When staring at competitor price changes, it is recommended to setDynamic Acquisition Strategy::
- 30-minute collection interval during daytime peak hours (10-18 p.m. Tokyo time)
- 2-hour collection interval during nighttime low hours
- Automatically triggers real-time acquisition in case of sudden price changes
This elasticity strategy combined with ipipgo's millisecond IP switching can stretch resource utilization to its fullest without blocking.

Frequently Asked Questions QA

Q: Do I have to use a local proxy in Japan? Is Hong Kong node OK?
A: Never! Japanese platform is particularly sensitive to domestic IP, we measured the Hong Kong node survival is not more than 2 hours, Tokyo machine room IP can be stable to run full 24 hours.

Q: Would it be faster to have more than one collection program on at the same time?
A: Re! Suggest single threading with automatic IP rotation. With ipipgo's concurrency mode, 1 program hangs 500 IPs to switch automatically, which is safer than opening 10 programs.

Q: What should I do if I encounter a CAPTCHA?
A: Immediately stop the current IP request, change to a new IP and then reduce the collection frequency. ipipgo has an intelligent blocking warning function in the background, which will mark the suspicious IP segments in advance.

Finally, a cold knowledge: Japanese platforms update their anti-climbing strategies at 3:00 a.m. every day, and it is recommended that the collection parameters be reset at this point in time. With the right tool plus the right method, data capture this thing is really not difficult to imagine. Conditional recommendations directly on the ipipgo customized program, their technical support can help to adjust the reference, than their own toss to save a lot of heart.
