Did all deposits post?	Incoming amounts

Tsukiawase vs Shogou (照合)

You might also hear the term Shogou. While they are often used interchangeably, there is a subtle nuance difference in Japanese business culture:

Comparison Table

Aspect	Shogou (照合)	Tsukiawase (突合せ)
English	Verification	Reconciliation
Type	Often 1-to-1	Often Many-to-Many
Formality	Higher	More everyday
Complexity	Simple check	Complex matching
Example	ID verification	Invoice matching

Visual Analogy

Term	Image	Description
Shogou	🆔 vs 👤	Check if this ID matches this person
Tsukiawase	🧾🧾🧾 vs 📦📦📦	Match these invoices to these deliveries

Tsukiawase implies a grittier, more volume-heavy task than Shogou.

Why is Tsukiawase So Painful?

Problem 1: The “Fuzzy” Issue

Japanese business data is notorious for inconsistencies:

Variation Type	Example A	Example B
Abbreviations	Panasonic Corp.	Panasonic Corporation
Japanese style	株式会社ABC	(株) ABC
Character width	ABC（全角）	ABC（半角）
Spacing	株式会社 ABC	株式会社ABC

To a human, these are obviously the same. To Excel (VLOOKUP), they are completely different, resulting in endless #N/A errors.

Problem 2: Overwhelming Volume

Volume	Visual Check	Accuracy
5 items	Easy	High
50 items	Tedious	Medium
500 items	Exhausting	Low
5,000 items	Impossible	Guaranteed errors

Checking 5 items is fine. Checking 5,000 items visually is impossible without making mistakes. And in accounting, mistakes are not allowed.

Problem 3: Time Pressure

Period	Pressure	Risk
Month-end	High	Overtime
Quarter-end	Very high	Errors increase
Year-end	Extreme	Burnout

Problem 4: Person Dependency

Issue	Impact
Only one person knows	Bottleneck
That person is absent	Work stops
That person leaves	Knowledge lost

Traditional Methods

Method 1: Manual (Ruler and Red Pen)

Pros	Cons
No special skills	Very slow
Reliable process	Exhausting
Audit-friendly	Error-prone when tired

Method 2: Excel Functions

Tool	Limitation
VLOOKUP	Exact match only
Conditional formatting	Still need to review
Pivot tables	Aggregate level only

Problem: Faster than manual, but fragile and requires data cleaning.
